THE CONTRIBUTIONS OF TOTAL QUALITYMANAGEMENT TO A THEORY OF

WORK PERFORMANCE

DAVID A. WALDMANConcordia University

Based on recently proposed principles oi total quality management(TQM), a system-focused perspective is considered here with regard tothe determinants oi work performance. The system is seen as an im-portant source oi variance aiiecting periormance both indirectly andinteractively. Moreover, the individual is seen as potentially affectingthe system. Hierarchical level and autonomy are considered as keymoderating variables in understanding individual versus system in-fluences on work performance. Implications are discussed with re-gard to performance management processes in organizations.

Human resources management (HRM) theory and practice have formany years focused on individual differences in the management of per-formance in organizations. Indeed, researchers in areas such as selec-tion, performance appraisal, and compensation have been concernedmainly with decision making based on the assessment of individual dif-ferences. An underlying assumption has been that individuals matter indetermining the variation in work performance. Proponents of total qual-ity management (TQM) have not disputed this assumption. However, theyhave questioned the predominant focus on individuals and, instead, havechosen to emphasize aspects of work systems as being relevant to workperformance (Deming, 1986, 1993; Juran, 1989; Walton, 1986). The implica-tions of a system-oriented perspective are enormous with regard to thetheory, research, and practices of HRM.

Unfortunately, a clear theoretical framework presently does not existto show the connections between aspects of systems and the work per-formance of individuals within those systems. The purpose of this articleis first, to provide such a framework and second, to use this framework togenerate research propositions that focus on the interplay of person andsystem factors. In doing so, an attempt is made to incorporate principlesrecently put forth in the TQM literature.

Elements of TQM

Companies have been concerned with the quality of their productsand their quality-management processes for years. However, only sincethe mid-1980s have organizations paid serious attention to the implemen-tation of TQM. TQM has its origins in manufacturing, where statisticalquality-control measures were first used to reduce product defects. How-ever, TQM has spread to include applications in service industries andgovernment (Brown, 1991; Cohen & Brand, 1993).

TQM has evolved as an approach to quality that it is now character-ized in terms of an integrated, systematic, organizationwide strategy forimproving product and service quality (Dean & Evans, 1994; Tenner &DeToro, 1992). TQM is neither a program nor a specific tool or technique.Rather, TQM may be viewed as a shift in both thinking and organizationalculture (Sashkin & Kiser, 1993).

A review of the literature reveals that TQM encompasses a vast spec-trum of topics and perspectives. A number of individuals associated withthe TQM movement have been highly critical of Western managementpractices. Among these, perhaps the one most strident in his claims hasbeen W. Edwards Deming. Deming (1986) summarized his managementphilosophy around 14 principles he offered as requirements to remaincompetitive in providing products and services. These include manage-ment commitment and leadership, statistical process control, removal ofbarriers to employee participation and control of their own quality, andcontinuous improvement of processes. Juran (1964, 1989) emphasizedplanning and product design, quality audits, and orienting quality man-agement toward both suppliers and customers. Crosby (1979, 1984) fo-cused on such organizational factors as cultural change, training, lead-ership, and the ongoing calculation of quality costs. Important extensionsto the TQM framework have included the development of customer-basedspecifications in the design of a product or process (Taguchi & Clausing,1990) and benchmarking or the measuring of products/services and pro-cesses against those of organizations recognized as leaders (Camp, 1989).Taken together, the following elements appear to be key to TQM:

1. Upper management commitment to place quality as a top priority.2. A broad definition of quality as meeting customers' expectations at the

least cost, which encompasses all phases of the design, production,and delivery of a product/service.

3. The institution of leadership practices oriented toward TQM valuesand vision.

4. The development of a quality culture.5. Involvement and empowerment of all organizational members in co-

operative efforts to achieve quality improvements.6. An orientation toward managing-by-facts, including the prolific use of

scientific and problem-solving techniques such as statistical processcontrol.

The TQM Perspective of Work Performance

Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding connections between total qualityand work performance and the management of such performance. Spe-cifically, Deming built a case that the central problem of management isan incorrect understanding of variation in performance phenomena, in-cluding the work performance of employees. His lament focused on theconfusion between speciai causes and common causes of variation. Spe-cial causes are sporadic in nature; with regard to work performance, theycan include factors unique to the individual worker. These causes wereseen by Deming as being separate from the system in which the individ-ual operates, not commonly affecting other workers. An example might bethat a worker shows truly extraordinary effort significantly beyond theefforts shown by other workers. Conversely, another worker might showvirtually no effort, which places the performance of that individual sig-nificantly below the performance of the others.

However, the sporadic nature of special causes is evident in Dem-ing's proposal that relatively little of the variance in work performance isdue to such causes. In contrast, he proposed that the vast majority ofvariance is due to common causes which, according to Deming, are sys-tem based. Furthermore, managers are responsible for correcting system-based causes of performance. "No amount of care or skill in workmanshipcan overcome fundamental faults in the system" (Deming, 1986: 315). TQMproponents have been quick to criticize performance appraisals that arebased on the assumption that the employee is mainly in control of his orher performance (Deming, 1986; Scherkenbach, 1985; Scholtes, 1987; Wal-ton, 1986).

It is not surprising that Deming would attribute the lion's share ofvariation in work performance to common or system causes. Such reason-ing follows from statistical process control and probability theories thattreat data within plus or minus three standard deviations from a mean asnot being statistically different from that mean. Thus, Deming wouldclaim that a mean performance level simply reflects a system's overallcapability. Variation around that performance level within plus or minusthree standard deviations is system based and random in nature.

Deming neither makes clear the exact nature of the system constructnor the manner in which it is related to performance outcomes. For ex-ample, if most of the variation in work performance is due to systemvariables, are the relationships direct? Does the system affect perfor-mance indirectly by first affecting aspects of individuals? Are there in-teraction effects between the system and the individual in the determina-

tion of performance? Moreover, pofenfial boundary condifions are alludedfo by Deming (1986) buf not made very clear. An example is hierarchicalor managemenf level. Deming suggested that workers work in a system,the creation and perpetuation of which are the responsibilities of man-agement. It would logically follow that for workers, most performancevariation might be due to system factors beyond their control. The situa-tion is not as clear for managers. If managers are responsible for systemdevelopment, is it logical to minimize the contribution of their individualabilities and effort in the determination of their own work performance?Moreover, individual abilities and effort may be similarly relevanf forworkers whose jobs allow for a high degree of autonomy. These issuesare addressed in a later section as a system-focused framework ofwork performance is developed and illustrated by considering TQM con-texts.

Dobbins, Cardy, and Carson (1991) recently considered the implica-tions of TQM system-based approaches on practices and research issuesin HRM. In essence, they contrasted such approaches with the more tra-ditional and still dominant emphasis in HRM on the person orientation.Qne conclusion reached by Dobbins and his colleagues is that HRM re-search would greatly benefit from the development of a fheory of workperformance that carefully delineafes the role of system factors. Such atheory would logically benefit by including concepfs being generafed byTQM proponenfs.

A system-focused approach fo fhe modeling of work performance maybe especially opporfune at this point in time. Prior research attempting topredict work performance behavior has been criticized for being too nar-row in focus and involving too few antecedent variables (Blumberg &Pringle, 1982; Griffin, Welsh, & Moorhead, 1981; Staw, 1977; Waldman &Spangler, 1989). That is, there has been a tendency on the part of re-searchers to use a single theoretical area such as motivation (see Camp-bell & Pritchard, 1976) as the basis for modeling work performance. How-ever, it may be more beneficial for theorists and researchers to work froman integrative perspective involving multiple theories (Colarelli, Dean, &Konstans, 1987; Staw, 1984; Waldman & Spangler, 1989).

As stated by Blumberg and Pringle (1982: 561), "unfortunately, thefocus has been on a few trees, and there has been little or no attempt toshow how these trees form the interrelated patterns that are the forest."Blumberg and Pringle (1982) attempted to integrate various perspectivesand models of work performance determinants. A primary focus of fheBlumberg and Pringle model was to explicitly include opportunity facfors,or environmenfal influences beyond an individual's control, as determi-nants of performance. Indeed, fhey were critical of prior approaches to themodeling of work performance that tended to treat opportunity factors asspurious in nature or unnecessary in terms of operationalization and mea-surement in research (Cummings & Schwab, 1973; Dachler & Mobley,1973; Porter & Lawler, 1968). That is, early models of work performance

Page 5: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

514 Academy of Management Review July

fended to focus on individual ability and motivation determinants, andopportunity factors were treated as somewhat extraneous. Even more re-cently, Campbell (1990: 707), in attempting to model work performance,omitted opportunity factors and simply assumed that they could "be heldconstant (experimentally, statistically, or judgmentally)." Despite the fre-quent lack of direct theoretical attention to opportunity factors, researchhas shown how variables outside of the individual can be linked to workperformance. Generally concentrating on phenomena in an individual'simmediate work environment, researchers have included the role of lead-ership processes (Bass, 1985; Yukl, 1989), job design (Hackman & Qldham,1980), person/system fit (Chatman, 1989; Q'Reilly, Chatman, & Caldwell,1991; Schneider, 1985), and situational constraints (Johns, 1991; Peters &O'Connor, 1980). More will be said about each of these sources of influ-ence in following sections.

When conceptualizing the determinants of work performance, it maybe especially beneficial to include concepts and ideas being put forth byTQM proponents such as Deming and Juran. To do so might lead to thetype of transformational effect in theory building described by Bacharach(1989). That is, TQM may force the reevaluation and reconceptualizationof existing models of work performance. Whetten (1989) suggested thatsuch a transformational effect results from borrowing perspectives froman area or line of thinking substantially disparate from traditional ration-ales and theories. With regard to work performance and its management,traditional approaches have been mainly psychological in nature with anemphasis on the individual. As noted previously, TQM is predicated onstatistical concepts of variation, and its proponents approach such issuesas work performance by targeting system-based causes of variation(Deming, 1986; Juran, 1989; Sashkin & Kiser, 1993).

WORK PERFORMANCE AND SYSTEMS

Work Performance

Work performance is defined here as behavior associated with theaccomplishment of expected, specified, or formal role requirements onthe part of individual organizational members (Campbell, 1990). Thus,work performance includes in-role behavior that can be contingently tiedto rewards. As such, attempts have been made to distinguish it from otherforms of performance such as organizational citizenship behavior (QCB).OCB has been viewed as discretionary, not formally recognized by orga-nizational reward systems, and more geared toward enhancing groupand organizational effectiveness (Moorman & Blakely, 1993; Organ, 1988).

In a TQM context, it may be difficult to separate work performancefrom OCB. For example, Bushe (1988) described a total quality culture interms of norms, values, and reward procedures that emphasize holisticbehavior oriented toward cooperation with fellow organizational mem-bers. Work performance in such a culture would tend to be defined

Page 6: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 515

broadly to include accomplishing tasks and taking initiatives above andbeyond the call of duty, and sharing information with and helping co-workers. Moorman and Blakely (1993) included such behaviors under therubric of OCB. Yet, in a TQM context, these behaviors might be bothexpected and formally rewarded (Bushe, 1988; Scholtes, 1988).

Some support for this notion can be seen in the work of Blackburn andRosen (1993). In describing the performance appraisal and reward sys-tems of Malcolm Baldrige National Quality Award winners, anecdotaldata were reported showing how such organizations tend to emphasizedimensions such as engaging in continuous improvement initiatives andcontributions to teamwork. Thus, it would appear that organizations iden-tified as representative of TQM may be defining, measuring, and reward-ing work performance in terms that have been previously conceived asOCB. That is.

Proposition 1: As organizations achieve gieatei degreesof TQM implementation, theie will be an increasing ten-dency to define, assess, and iewaid woik performancein terms of OCBs oriented toward the continuous im-provement of the group or organization.

SystemsA key assumption of the model I propose is that system factors play a

pivotal role in the determination of observed levels of work performance.Dobbins and colleagues recently attempted to relate TQM to HRM theoryand practice (Carson, Cardy, & Dobbins, 1991; Dobbins et al., 1991). Theyprovided a sharp separation of person and system factors without con-sidering possible linkages between these two sets of factors. Person fac-tors pertain to differences between individuals in terms of ability or mo-tivation, and these have been well addressed by researchers in the areaof industrial psychology (e.g., Campbell, 1990). Such factors have beenshown to account for as much as 28 percent of the variance in work per-formance measures (Hunter & Hunter, 1984). Carson and colleagues (1991)also acknowledged the relevance of system factors that were defined toinclude existing work processes and technological constraints. However,they questioned Deming's (1986) estimate of the importance of such factorsin determining work performance. The problem is that even though he didnot offer a specific typology, Deming (1986) did suggest that system fac-tors go beyond work processes and technology. Specifically, he noted that"few people in industry know what constitutes a system. Many peoplethink of machinery and data processing when I mention system. Few ofthem know that recruitment, training, supervision, and aids to productionworkers are part of the system" (Deming, 1986: 366).

Similar to Deming (1986, 1993), a broad perspective of what consti-tutes a performance system is taken here. In line with general systemstheory, a system is defined as a network of interacting units and pro-cesses intended to realize some purpose (Ashforth, 1992; Miller, 1971).

Page 7: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

516 Academy of Management Review July

Processes endogenous to the system are conceived in terms of a widerange of interpersonal, organizational, and technical factors. Similar per-spectives have been taken by other management theorists (e.g., Blum-berg & Pringle, 1982; Lofquist & Dawis, 1969; Peters & O'Connor, 1980;Peters, O'Connor, & Eulberg, 1985).

Broad conceptions of systems and their impact on human behaviorare not uncommon. For example, sociotechnical systems theory empha-sizes the interplay of both social and technical aspects of a work systemand that both must be optimized to achieve performance effectiveness inorganizations (Cherns, 1976; Trist, Higgin, Murray, & Pollock, 1963).Homans (1950) discussed the sociology of work groups by carefully con-sidering physical, technical, and social influences on performance andother behavioral phenomena.

An important issue with regard to systems involves the manner inwhich system factors may affect variation in individual work perfor-mance. As noted previously, Deming (1986) argued that system factors arehighly influencial in determining performance variation within an orga-nization. However, the system could potentially be viewed as a constant,affecting each individual within that system equally. It would then followthat any observed variation in performance must be due to person-basedfactors.

I take a somewhat different perspective of systems and work perfor-mance variation. My viewpoint, in line with that of Dobbins and his col-leagues (1991), is that work performance may be influenced by four pos-sible categories of factors: (1) systematic system, (2) random system, (3)person, and (4) person/system interaction. However, performance varia-tion within a system will only result from the latter three categories.Systematic system factors are those that affect individuals equally. Forexample, employees on a manufacturing line use the same automatedprocess, and their performance is affected equally by that process. Thiscategory cannot explain variations in individual performance.

In contrast, random system factors affect employees differentially.The term random implies the uncontrollable and, therefore, the dismiss-able. However, Deming (1986) and Juran (1989) described how such factorsmay be controllable and, therefore, important. For example, individualsmust deal with variations in raw materials, environmental conditions,tool wear, leadership, supervision, and job design. Dobbins and col-leagues (1991: 11) provided an example of a sales representative who isfortunate enough to be assigned to an especially "hot" sales territory, ascompared to other sales representatives who are not so fortunate. In asystem that is not under control, random system factors can, indeed, playa large role in determining variation in individual performances. For asystem that is under control, variation would be decreased, as would theimpact of such factors on individual performance. In sum, conceptualiz-ing the system in terms of both systematic and random factors is consis-tent with the work of Deming (1986). For Deming, systematic factors

Page 8: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 517

determined the mean level of performance among individuals, whereasrandom factors accounted for most of the variance.

Person factors represent a third category that affects work perfor-mance. As noted previously, these factors have been preeminent in HRM,as well as in some attempts to model the determinants of work perfor-mance (e.g., Campbell, 1990). People also may interact with the system toform the fourth category. Even if a system is invariant, people may reactto it differentially because of their different abilities, values, expecta-tions, and so on. For example, some people may perform better on atraditional assembly-line process with autocratic management, whereasothers respond better to team-oriented assembly methods and high in-volvement of management.

Authors such as Blumberg and Pringle (1982) as well as Deming (1986)have conceived system factors to include processes both internal andexternal to an organization. The present conceptualization restricts thesystem to a consideration of only internal processes. The discussion be-low of potential reciprocal influences between the person and systemnecessitates such boundaries. It may be unlikely, and indeed unreason-able, to assume that organizational members can have a significant im-pact on system processes that are external to an organization. In addition,a temporal boundary is placed on the concept of system in the model thatfollows. That is, system factors are restricted to processes that are rela-tively current or ongoing in an individual's work context. For example,unlike Deming (1986), recruitment and selection processes are excludedfrom consideration as system factors. A temporal boundary is necessaryto avoid producing a model that would lead to overattributing perfor-mance behavior to the system.

It is important to note that system processes and factors exist at mul-tiple levels within an organization. Thus, a system factor can be organi-zationwide, affecting the performance of all individuals within that orga-nization. As an example, using the category of random system factors, anorganization as a whole may provide an inconsistent degree of training toindividual members, thus creating performance variance. Alternatively,a system factor can emanate from a subsystem within that system andapply only to those individuals within the subsystem. An example of howvariance may be increased at a subsystem level is when there is incon-sistent availability of tools or other raw materials for individuals within aproduction department. Inconsistent leadership or supervision practicesconstitute another example of a source of random variation within a sub-system (i.e., group).

Figure 1 provides a model of the determinants of work performancethat is based mainly on the previous discussion of system influences. Thecurrent model represents a significant addition to the literature for tworeasons. First, prior attempts to treat system sources of variation as errorsor nuisances to be controlled can no longer be regarded as viable in thestudy of work performance (cf. Campbell, 1990). The present approach

explicitly considers system factors. Second, prior theorists have eitherfailed to take into account linkages between person and system factors(e.g., Dobbins et al., 1991) or have not been clear with regard to the natureof such linkages (e.g., Blumberg & Pringle, 1982). Blumberg and Pringle's(1982) model can be viewed as largely representative of current thinkingwith regard to the modeling of work performance. However, their ap-proach did not go far enough in delineating connections between personand system factors, or the manner in which they may interact in deter-mining work performance. Chatman (1989) stated that truly interactivemodels should take into account the reciprocal effects of persons on sit-uations and situations on persons.

A MODEL OF WORK PERFORMANCE

In general terms. Figure 1 portrays how person/system linkages areessential in attempting to understand how the system is relevant to thedetermination of work performance. As compared to prior theory (e.g.,Blumberg & Pringle, 1982), the current approach attempts to provide anin-depth consideration of the reciprocal influence between person andsystem factors. System factors encompass two sets of constructs: (a) per-son enhancers and (b) system constraints and demands. Person enhanc-ers within a system are viewed as influencing aspects of the individual'sability and motivation. System constraints and demands interact with theperson in terms of person/system fit in the determination of performance.The individual also is seen as potentially affecting system constraints

and demands, especially at higher management levels and in jobs thatallow for more autonomy. Hierarchical level and autonomy are furtherportrayed as moderating relationships between person factors and workperformance and between system constraints and demands and workperformance. Finally, the current model and associated propositions at-tempt to glean contributions from, and provide applications toward,evolving TQM concepts. It should be noted that the propositions thatfollow should be viewed as examples of those that can be derived fromthe current framework.

Person Enhancers

Person enhancers are shown in Figure 1 as a category of systemfactors that affect performance indirectly by first influencing aspects ofthe individual. In line with earlier models of work performance (e.g..Porter & Lawler, 1968; Vroom, 1964), individual factors are conceptualizedin Figure 1 in terms of work-relevant knowledge, skills, and abilities andmotivation. Person enhancers are proposed to involve aspects of HR sys-tems, leadership processes, and job design that may develop and moti-vate individuals. It should be noted that these categories of enhancers arenot meant to be exhaustive of the factors in a work system that mightaffect the knowledge, skills, and abilities and motivation of individuals.However, they are included here because of the emphasis placed on themin TQM literature in terms of contributing to the systematic and randomsystem-based performance variation described previously.

Knowledge, skills, and abilities. TQM proponents have been partic-ularly vocal in their plea for system-generated activities oriented towardthe continuous training and development of organizational members(Brown, 1991; Deming, 1986; Juran, 1989; Walton, 1986). For an increasingnumber of jobs, such activities will have to be planned on a continuousbasis over a person's working lifespan if work-relevant competencies areto be ensured. This situation is accentuated by the fact that jobs andrequired skills appear to be changing at ever increasing rates (Dobbins etal., 1991).

A number of parallels can be drawn regarding literature aboutworker obsolescence. Fossum, Arvey, Paradise, and Robbins (1986) de-fined obsoiescence as a longitudinal process characterized by a growingincongruence between an individual's knowledge, skills, and abilitiesand the current demands and requirements of his or her work. Relevant tothe obsolescence process, evidence has shown how prolonged exposureto unchallenging or routine work and nonwork activities may contributeto reduced cognitive ability (Avolio & Waldman, 1990; Denney, 1982). TQMproponents have been quick to point out that work-related competenciescan best be maintained over time by continuous training and develop-ment activities not only in technical aspects of the job, but also withregard to quality-related knowledge and skills (Deming, 1986; Juran,1989).

520 Academy of Management Review July

Motivation. Person enhancers also may have an impact on work per-formance by first affecting aspects of motivation. Motivation is defined interms of the direction, intensity, and persistence of individual effort(Campbell & Pritchard, 1976; Kanfer, 1990). Motivation is obviously a verybroad concept that cannot be fully considered here in terms of its rela-tionship with work performance. The current purpose is to limit the dis-cussion to aspects of motivation that may be particularly influenced byperson enhancers within a system and especially to illustrate relevantTQM perspectives and implications. These aspects include self-efficacyand instrumentality beliefs, goal setting, values, and internal (i.e., in-trinsic) motivation. Proposed system factors emphasized by TQM propo-nents as affecting motivation include (a) reward system and leadershipprocesses and (b) job design.

The degree to which an individual obtains the outcomes expectedfrom a certain level of performance will influence that person's futureperformance-outcome instrumentalities and, thus, future motivation(Gist, 1987). For example, if an individual originally believed that a cer-tain level of performance would result in a specific pay bonus, and thepay bonus actually materialized after that performance was achieved,future performance-bonus beliefs would be strengthened. Based on workinvolving procedural justice issues (e.g., Folger & Konovsky, 1989), suchcognitive contingencies also should depend on the extent to which theindividual perceives that his or her performance level is fairly evaluated.Research has confirmed the motivational impact of contingent reinforce-ment practices (Komaki, 1986; Luthans, Paul, & Baker, 1981; Podsakoff,Todor, & Skov, 1982).

Leadership has been conceived as an influence process whereby theleader seeks to have an impact on followers' beliefs and values, therebyresulting in subsequent behavior changes (e.g., performance improve-ment) (Yukl, 1989). Transactional forms of leadership follow from contin-gent reinforcement theory and have been predominant in the literature(House & Mitchell, 1974; Podsakoff et al., 1982). Such leadership stresses(a) a clarification of follower roles and goals and (b) the ways in whichfavorable outcomes will follow from the successful accomplishment ofroles and goals. As such, transactional leadership should be effective instrengthening follower performance-outcome instrumentalities as well astheir acceptance and commitment to goals (Locke, Latham, & Erez, 1988).However, transactional leadership also may encourage the type of short-term, individually based goal setting for which TQM proponents havebeen especially critical. For example, management by objectives hasbeen criticized for encouraging short-term individual performance, poten-tially to the detriment of group-level goals and continuous improvement(Deming, 1986; Walton, 1986).

Transformational leadership is a somewhat different paradigm thathas stressed the enhancement of self-efficacy beliefs and ideological val-ues on the part of followers. By showing confidence in followers and

helping them to work through individual problems or self-doubt, trans-formational leaders are able to raise the self-efficacy of followers (Bass,1985; Eden, 1984; Gist, 1987). Such self-doubts may be especially prevalentin organizations attempting to implement TQM through continuous pro-cess improvement. Scholtes (1988) reported that individuals frequentlyencounter intransigent processes and well-established bureaucracy intheir attempts to engage in continuous process improvement. Scholtessuggested that empathetic, facilitative leadership behavior is essential toensure persistent efforts.

Transformational leadership processes also have the potential to en-hance followers' work-oriented values to be in line with those of thegreater group or organization (Burns, 1978; Conger & Kanungo, 1987). Sev-eral processes are likely to be operating when a leader stimulates thetransformation of values. First, the leader may demonstrate high degreesof confidence and moral conviction in the righteousness of his or her ownvalues (House, 1977). Second, a clear and appealing vision is espoused,thus generating enthusiasm for certain value-laden or ideological goals(Conger & Kanungo, 1987; Tichy & Devanna, 1986). Finally, the leaderserves as a role model for the value system. Bass (1985) described theoutcomes of transformational leadership in terms of extra effort and per-formance beyond expectations on the part of followers.

Such forms of leadership appear to be very much in line with the typeof leadership to which TQM proponents have frequently referred in theirpleas to managers (Deming, 1986; Juran, 1989; Sashkin & Kiser, 1993). Forexample, managers have been exhorted by Deming (1986: 24) to have a"constancy of purpose." In other words, Deming is proposing that man-agers should pursue diligently the long-term goal of remaining compet-itive through continuous improvement processes. They also should com-municate an appealing vision emphasizing continuous improvement,teamwork, and customer service in order to inspire followers. Moreover,managers can act as role models by taking a personal interest in activi-ties geared toward improving processes and customer relationships. Insum, transformational leadership can be viewed as the mechanism bywhich managers may shape individuals' self-efficacies and values to per-form in such a way as to benefit teamwork to achieve group goals and thecontinuous improvement of processes (Waldman, 1993). It remains, how-ever, unclear as to whether transformational leadership should be con-sidered a systematic subsystem variable, as opposed to a random sub-system variable. Some theorists have considered its potential to have auniformly positive effect on performance within a group, which is in linewith the notion of systematic subsystem influence (Bass, 1985; Burns,1978). However, research has shown that the display of such leadershiptends to vary within a group, thus aligning it more with random sub-system variation (Yammarino & Bass, 1990). Taken as a whole, it is ex-pected that

Proposition 2: Trans/ormafionai leadership will sfimu-late foUowei self-efficacies and woik values orientedtoward teamwork and the continuous improvement ofwork processes.

Job design represents an additional form of person enhancer within asystem that can affect motivation and can be linked to concepts evolvingfrom TQM. A classic approach to job design was put forth by Hackmanand Oldham (1980) in terms of job characteristics theory. Along similarlines as the current model, Hackman and Oldham maintained distinc-tions between person factors and system factors. A key system factorinvolved characteristics of jobs. Hackman and Oldham described severalimplementing principles for job design, at least three of which are quiterelevant to TQM. The principle of establishing client relationships in-volves giving employees direct communication and responsibility formanaging relationships with clients, presumably including those eitherinternal or external to the organization. As an example, Jacob (1993) re-cently described Johnson & Johnson's efforts to allow workers the oppor-tunity to visit special booths in production facilities where they could hearquestions and complaints directly from outside customers through an 800telephone line.

Hackman and Oldham (1980) included the task of deciding when andhow to check on the quality of work produced as an example of verticalloading. This notion was repeated in their consideration of ways of open-ing feedback channels. As noted by Hackman and Oldham, jobs tradi-tionally have been designed such that quality checks on products or ser-vices are done by individuals other than those actually responsible for thework. As a number of writers in the TQM literature have insinuated, suchforms of job design do not encourage organizationwide ownership ofquality problems or teamwork to improve quality (Dean & Evans, 1994;Deming, 1986; Tenner & DeToro, 1992). Hackman and Oldham suggestedthat allowing workers to control their own quality also would serve toincrease direct feedback provided by the job. In sum, it appears that jobdesign geared toward quality might encourage performance beyond in-role requirements and, ultimately, should result in more involved em-ployees who attempt to work with others to assure quality improvement(Sashkin & Kiser, 1993). It should be noted that job design would be seenas a systematic system factor when applied evenly across individualswithin a system. In contrast, job design is a random system variable whenapplied unevenly (i.e., when job characteristics are not the same acrossindividuals).

Williams and Bunker (1993) recently proposed a revised version of thejob-characteristics model more in line with the general model of workperformance portrayed in Figure 1. They noted that work performance hasnot been consistently predicted by prior research on job characteristics

Page 14: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 523

(cf. Fried & Ferris, 1987). Three reasons may account for this inconsis-tency. First, changes in job design are not likely to improve in-role per-formance unless the new procedures and methods are at least as efficientas the old ones (Katzell & Thompson, 1990). Second, when a job is high onjob characteristics, individuals may devote more time to precision or de-tails, thus enhancing work quality at the expense of work quantity. Yet,organizations often emphasize quantity in their measures of work perfor-mance. Third, similar to earlier possibilities suggested by Hackman andQldham (1976), Williams and Bunker (1993) viewed behavioral outcomessuch as work performance to be more causally remote from job charac-teristics, as compared to attitudinal outcomes. They proposed that jobcharacteristics and associated psychological states influence the attitu-dinal outcome of internal work motivation, which, in turn, influencesextra role performance defined mainly in terms of QCBs. Thus, the inter-nal work motivation achieved through enriched work may cause individ-uals to go beyond in-role requirements to engage in the types of extra-rolebehaviors stressed by TQM. That is.

Proposition 3: Internal work motivation derived from en-riched work will lead to extra-role performance behav-ior, including engaging in teamwork and continuousimprovement activities.

System Constraints and Fit

A number of authors have described how various factors can serve asconstraints on work performance behavior (Davis-Blake & Pfeffer, 1989;Johns, 1991; Peters & Q'Connor, 1980; Peters et al., 1985). Such constraintsmay limit the extent to which individual qualities are able to affect per-formance behavior. As conceived here, system constraints and demandsrefer to characteristics of technological and work processes, as well asorganizational policies, structure, and culture. Bowen, Ledford, andNathan (1991) described how bureacratic structures and policies also canserve to constrain variation in work performance. Davis-Blake and Pfeffer(1989) argued that situational effects were probably more important thanindependent dispositional qualities in terms of influencing an individu-al's attitudes and behavior in organizations. They specifically noted thatorganizational settings are strong situations that have a large impact onindividual attitudes and behavior, thereby limiting the extent of distinctdispositional effects (i.e., effects that can be conceived independently ofthe situation). Empirical support for the notion that inhibiting situationalconstraints can lead to lower work performance has been obtained for avariety of material resources and physical work-environment variables(Kim & Campagna, 1981; Steel & Mento, 1986; Sundstrom, Burt, & Kamp,1980).

Figure 1 portrays aspects of system constraints and demands inter-acting with aspects of the person in the determination of performance.

Page 15: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

524 Academy of Management Review July

These processes were introduced previously as person/system interactionfactors and can be viewed in terms of fit. Schneider (1985) considered theimportance of congruence or fit of the person to the setting but suggestedthat no taxonomies existed for specifying relevant research in the area.Lofquist and Dawis (1969) proposed a theory of work adjustment based onthe concept of correspondence between the person and work environ-ment. Correspondence was defined in terms of the mutual fulfillment ofrequirements on the part of both the person and the environment. Lofquistand Dawis (1969: 46) suggested that to ensure maximum "satisfactoriness"or performance, both work-related abilities and personality characteris-tics should be matched to stimulus conditions established by an organi-zational context.

Chatman (1989) introduced a conceptualization of person/system fitthat follows from the Lofquist and Dawis (1969) approach. Person/systemfit possibilities were considered with regard to two aspects of systemfactors: (a) work and job demands and (b) organizational culture. Theformer possibility includes the notion that individuals may need to bematched to work and occupational requirements in terms of knowledge,skills, and abilities. Hunter (1980) provided a classification of job types forwhich cognitive abilities, as opposed to psychomotor abilities, are morerelevant to the determination of work performance. Work involving com-plex cognitive activities requires a high degree of general cognitive abil-ities; work involving manual activities requires more psychomotor abili-ties.

Patterns of an individual's motives also may differentially predictwork performance, depending upon the job and its demands. Motives arerelatively stable individual needs that drive behavior such as work per-formance (McClelland, 1985). McClelland's work has focused on need forachievement, need for power, and need for affiliation. Some initial re-search has shown how optimal motive patterns may vary for differenttypes of managers. In general management positions, effective individ-uals have been shown to be high on need for power and relatively low onneeds for affiliation and achievement (Cornelius & Lane, 1984; McClel-land & Boyatzis, 1982). Such results suggest that general managementrequires persuasiveness and the desire to assert influence and exercisecontrol over others. In contrast, technical managerial positions, such asthose found in R&D, may require individuals with a high need for achieve-ment attained through personal persistence (Varga, 1975).

Despite these beginnings, additional research is necessary to pro-vide a broader understanding of motive fit requirements. For example, itis not clear as to the appropriate motive pattern for managers in a TQM-oriented organization. Perhaps the motive pattern for general manage-ment positions described would still be largely appropriate. However, ina TQM context, it may be particularly important for managers to possessa high degree of socialized power or activity inhibition (McClelland,1985). That is, managers in such a context would need to use their power

1994 Waldman 525

to empower others and to further organizational goals, rather than theirown personal goals. The importance of employee empowerment in a TQMcontext has been discussed at length by Sashkin and Kiser (1993). Theirarguments center around the need for employees in TQM settings to feelempowered to take initiatives and appropriate actions to solve quality-related problems. In general.

Proposition 4: Individual motive patterns will interactwith job demands and organizational context in the de-termination of work performance.

Chatman (1989) also focused on the importance of person/system fit interms of the congruence between the cultural norms and values of anorganization and comparable norms and values of persons within thatorganization. For the present discussion, organizational culture can beviewed as a form of system constraint or demand that may interact withthe person in the determination of performance. Chatman (1989) describedhow person/organizational culture fit could be achieved in several ways.These include individuals gravitating toward organizations with normsand values congruent with their own, organizations selecting congruentindividuals, and socialization processes to ensure congruence. Bowenand colleagues (1991) proposed that selection processes should be moregeared toward attempting to fit individuals with organizations, ratherthan the traditional focus on specifically defined jobs. In line with thework of Chatman (1989), an important category of fit variables consideredby Bowen and colleagues (1991) included values and beliefs.

Other authors (O'Reilly et al., 1991) provided some evidence support-ing the importance of person/organizational culture fit in terms of predict-ing such outcomes as commitment and turnover. It is not established atthis point as to how such fit might affect actual work performance. How-ever, Chatman (1989) proposed that person/organizational culture fitwould be positively related to the type of extra-role performance behaviordescribed previously. She argued that individuals who share organiza-tional values would be "more likely to contribute to the firm in construc-tive ways" (Chatman, 1989: 343).

Because TQM organizations may be especially conducive to extra-role performance behavior, person/organizational culture fit and workperformance might be best understood in the context of TQM. Culture inTQM organizations has been referred to largely in terms of problem-solving and change orientations. Specifically, these orientations includepredominant norms and values that emphasize taking steps to learnabout problems and make appropriate changes, sharing information tofacilitate cooperative or teamwork efforts to deal with problems bothwithin and between groups, developing employees to deal with prob-lems, and having a customer-focused orientation (Bushe, 1988; Dean &Evans, 1994; Sashkin & Kiser, 1993). With regard to predicting individuals'work performance, a TQM organization logically would be on better foot-

Page 17: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

526 Academy of Management Review July

ing by having employees whose own norms and values are in line withthat organization's culture. At the individual level, such norms and val-ues include flexibility, the desire to leam and solve problems, and a teamorientation (Bowen et al., 1991; Dobbins, Cardy, & Carson, 1993). Similarto a team orientation, Moorman and Blakely (1993) stressed coUectivistvalues as opposed to individualism. Without such norms or values, it isnot likely that the individual will adjust to the TQM organization, and heor she would eventually be a candidate for turnover (Chatman, 1989). Ingeneral.

Proposition 5; Work performance will be maximizedwhen the norms and values of individuals are congruentwith the cultural norms and values of the organization.

The Effect of the Person on the System

An issue that has been largely ignored by prior conceptualizations ofwork performance is the effect of the person on the system. Figure 1 showshow the person can influence the system, especially at higher manage-ment levels and when work is designed in terms of autonomy. Prior the-orists have been adamant in their plea to researchers to consider recip-rocal influences between persons and the system, not just the effects ofthe latter. For example, Homans (1950) criticized sociologists for not con-sidering the effects of individuals on groups and society. Lofquist andDawis (1969) suggested that individuals may attempt to change their workenvironments to be more correspondent with their own personalities.Chatman (1989) noted growing evidence of how people are able to changesituations.

Schneider (1985) strongly suggested the importance of managers ineffecting change in organization system functioning and design. Suchthinking has been echoed by a number of other authors. For example,Hambrick and Mason's (1984) upper echelons perspective was basedmainly on the notion that strategic choices and change are reflective oftop-managers' values and cognitive bases.

Katz and Kahn (1978) suggested the importance of maintaining a sys-tem perspective. They specifically described how it is possible, indeedessential, for higher level managers to engage in the "subordination ofstructure" (Katz & Kahn, 1978: 543). Subordination of structure entails theorigination of new structures and policies (i.e., asserting freedom fromexisting structures or policies when necessary to improve social or tech-nical systems). The notion of leadership as a mechanism to embed orga-nizational culture is germane to Katz and Kahn's (1978) arguments. Schein(1990) argued that there tends to be constant pressures on an organiza-tion's culture to evolve and change. Leaders of organizations may be ableto perceive elements of culture that are dysfunctional and then take stepsto change or re-create them.

Such concepts as the subordination of structure and culture creation

Page 18: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 527

appear to be most relevant at higher management levels (Katz & Kahn,1978). Increasingly, at lower levels, power and system-imposed con-straints may not allow individuals enough freedom to seriously affect thesystem. Ashour and Johns (1983) included in their list of constraints a lackof control over formal incentives, larger spans of control, and standard-ized work processes. Mintzberg (1983) also discussed the moderating ef-fect of hierarchical level on managers' abilities to make changes in thesystem. Top-level executives were seen as most capable of making sig-nificant changes because of their broad sources of power and influence.The control over top executives was viewed by Mintzberg (1983) as beingsomewhat diffuse in that external factors and constituencies tend to beill-defined, thus allowing leeway to make adjustments in the internalsystem. Conversely, lower level managers find it more difficult to makesignificant changes in the system because of bureaucratic control pro-cesses that limit their actions. Mintzberg (1983) and Donaldson and Lorsch(1983) also described a number of scenerios whereby external factors andconstituencies can put constraints on top executives. However, externallyimposed sources of influence should not be confused with lack of choice.That is, despite the importance of such influences on executive actionsand decision making, executives are mainly free to choose variouscourses of action that can include significant changes to the internalsystem (Donaldson & Lorsch, 1983; Hambrick & Finkelstein, 1987; Mint-zberg, 1983; Stewart, 1982).

The previous arguments are consistent with Deming's (1986) reason-ing about systems that may, at first glance, appear to be somewhat par-adoxical in nature. That is, Deming proposed that organizational mem-bers are mainly captured and constrained by system processes;nevertheless, managers (who are also organizational members) are re-sponsible for creating and shaping systems. A dichotomy based on hier-archy seems to be suggested by Deming, whereby managers at higherorganizational levels are increasingly able to have an impact on or toformulate systems.

As compared to hierarchical level, degree of autonomy may be amore comprehensive concept in reference to persons' abilities to influencea system. Thus, as previously discussed, autonomy may not only act as aperson enhancer to increase internal work motivation, it also may serve tomoderate the extent to which individuals are able to significantly influ-ence a system. Autonomy may be defined as the degree of freedom ordiscretion a person has over the task domain regarding activities such asdetermining procedures and scheduling (Ashforth, 1990; Hackman & Old-ham, 1980).

The effect of autonomy on system change may best be understood byconsidering its opposite, powerlessness, which has been defined in termsof a lack of autonomy (Ashforth, 1989). The end result of powerlessnesshas been described by Ashforth (1990: 30) as a state of "organizationallyinduced helplessness." It may be viewed as a syndrome whereby, because

Page 19: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

528 Academy of Management Review July

of a chronic lack of autonomy, the individual displays feelings of help-lessness and reduced job and organizational involvement (Ashforth, 1989;Martinko & Gardner, 1982). In sum, the individual develops the cognitionof being unable to affect organizational outcomes.

Work designed on the basis of autonomy can enable feelings of free-dom and power to effect change in the system. Lofquist and Dawis (1969)described how flexibility in a work environment enables individuals to tryto change it to increase their work adjustment. Professional occupationssuch as university professor generally are conceived in terms of auton-omy. Other occupations such as those involving manufacturing or routineclerical operations have more commonly been seen as lacking autonomy.However, Adler (1993) provided a case example of how workers at theNUMMI automobile manufacturing facility in California have been ableto make a number of significant changes to the work system. Adler con-cluded that these changes stem largely from the enhanced power andautonomy afforded to the workers in the NUMMI system. In total, thesearguments and findings suggest that

Proposition 6; The person will have a greater potential tohave an impact on system change at increasing hierar-chical levels of management and when work is de-signed with a higher degree of autonomy.

Hierarchical Level/Autonomy and Work Performance

The moderating effects of hierarchical level and autonomy on workperformance also follow from the prior discussion. Dobbins and col-leagues (1991) noted that even a system-based approach to work perfor-mance should include the increasing importance of person factors athigher management levels, independent of the system. That is, at higherlevels, the performance of managers is due more to inherent abilities andmotivation. Hambrick and Finkelstein (1987) defined managerial qualityas due in part from their ability and motivation to effectively enact dis-cretion. Specific managerial characteristics involved in enacting discre-tion may include such factors as cognitive complexity and aspirationlevel.

Autonomous job design also implies that work performance willmainly be a function of person factors. Autonomy enables individuals todemonstrate their own efforts and initiatives, as opposed to being subjectto constraints or demands imposed by the system (Hackman & Oldham,1980). It is interesting to note that the high degree of weight attributed byDeming (1986) to system factors may have been due in large part to pre-vailing norms in industry. That is, work traditionally has been designedlacking autonomy. Perhaps if the trend shifts toward more autonomy injob design, TQM proponents may give less credence to random system-based performance variation. In total.

Page 20: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 529

Proposition 7: Person factors will outweigh system con-straints and demands in the determination of work per-formance at increasing hierarchical levels of manage-ment and when work is designed with a higher degreeof autonomy.

RESEARCH ISSUES AND IMPLICATIONS

A number of research issues can be drawn from fhe above discussion.According fo Figure 1, fhe causal modeling of work performance shouldinclude bofh person and sysfem facfors and also consider the nafure oflinkages befween fhem. Increasingly, such research is being affempted(e.g., Schmidf, Hunter, & Outerbridge, 1986), although failure to includekey variables and their interrelationships could lead to spurious results(James, Mulaik, & Brett, 1982).

Subparts of the model also might be tested. For example, methodol-ogies such as those represented by the organizational culture profile(Chatman, 1989; O'Reilly et al., 1991) could be used to determine whetherperson/organization fit, in terms of norms and values, leads to enhancedwork performance in a TQM context. Although the instrument used byO'Reilly and colleagues (1991) included a number of items relevant toTQM, perhaps future research could particularly focus on TQM contexts.Along similar lines, Dobbins et al. (1993) provided an interesting exampleof how job-analysis methods could be used to develop behavioral inci-dents reflective of important values in TQM settings. Such methods couldresult ultimately in better selection and training procedures in organiza-tions attempting to implement TQM. Indeed, Levine (1993) provided anexample of a certified public accounting firm's attempt to use an instru-ment to screen for employees who could adapt to the firm's ongoing TQMimplementation.

Interesting leadership research is suggested by the present model.Bass (1985) originally proposed that transformational leadership wouldresult in extra effort and performance beyond expectations, although lit-tle research has directly tested this notion. In line with the prior discus-sion, a TQM organization might provide an excellent setting to examinethe effects of transformational leadership because such a context wouldtend to rely on work performance characterized by extra-role behavior.Research could help determine whether transformational leadershipdrives extra-role values and behaviors in TQM settings.

The present model implies that persons can affect the nature of sys-tem constraints and demands at increasing hierarchical levels in an or-ganization and when work is designed for autonomy. Questions remainas to what aspects of systems might be affected. For example, althoughthe notion of a system manager has been espoused in TQM literature, itis not clear as to what system features can be realistically changed bymanagers in organizations, especially at lower hierarchical levels. Tech-

Page 21: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

530 Academy of Management Review July

nological and bureaucratic constraints imposed at higher levels may pre-vent lower level managers from making any real changes to the system(Hammer & Turk, 1987; Mintzberg, 1983). Nevertheless, Ashour and Johns(1983) noted a degree of discretion on the part of lower level managers,especially with regard to workflow pacing and division of labor amongsubordinates. It is possible that a greater degree of TQM implementationin an organization serves to allow even lower level managers the oppor-tunity to make significant system changes. In short, research to sort outwhen and how managers can act as system change agents would bebeneficial.

Individual- and Unit-Level Work Performance

Linkages between individual- and unit-level work performance areimplied by the present discussion and should be the focus of future re-search. Although a separate consideration of unit-level performance isbeyond the scope of this article, it nevertheless has been seen as animportant topic in TQM literature (e.g., Deming, 1986; Sashkin & Kiser,1993; Scholtes, 1987). Schneider (1985) was careful to point out in his con-sideration of levels-of-analysis issues that the performance of individualscannot be simply summed to form the performance of a group or organi-zation, especially over time. He used the example of how even if it isknown that an individual incentive program leads to higher rates of in-dividual productivity, it does not necessarily mean that an organizationthat uses the program systemwide will be more productive. Staw (1986)also was quick to note possible discontinuities between individualisticversus more collectivistic approaches to motivation.

An individual incentive program represents an approach to the man-agement of performance that assumes that by enhancing individual taskperformance, the performance of the greater unit or organization subse-quently will be enhanced. TQM proponents have been critical of the useof individual incentive programs and related practices such as individu-alized goal setting (e.g., management by objectives) for at least two rea-sons. First, individuals may attempt to set or negotiate less challenginggoals to obtain rewards. Second, and perhaps more important from aTQM perspective, people tend to set goals that stress only short-termproductivity or short-term financial outcomes. Thus, because of self-interests, goals are pursued at the expense of the type of teamwork andcontinuous improvement efforts necessary to improve work systems andprocesses (Kerr, 1975; Scholtes, 1987, 1988). As noted by Deming (1986),traditional performance appraisal and associated reward mechanismsreward people who do well within the system. However, such proceduresaccomplish little in an attempt to improve the system. These are poten-tially growing problems because of the increasing interrelatedness ofindividuals' work activities and the need on the part of organizations tocontinuously improve to maintain their competitiveness.

It could be that the effectiveness of individual incentive procedures

Page 22: THE CONTRIBUTIONS OF TOTAL QUALITY …...The TQM Perspective of Work Performance Among the TQM proponents, the work of Deming (1982, 1986) is per-haps most relevant to understanding

1994 Waldman 531

may depend mainly on hierarchical level and autonomy. That is, thecurrent model implies that for higher level managers and for work thatinvolves more autonomy, person factors will tend to outweigh systemconstraints and demands in the determination of performance. Thus, forexample, the work performance of higher level managers might benefitfrom individualized incentive plans because such managers are not asconstrained in the utilization of their own person factors (cf. Abowd,1990). Conversely, lower level managers and those in unautonomous jobsmight be more constrained and not personally able to control their ownperformance as much as system factors do. They might, over time, be-come discouraged by incentive procedures that attempt to link the mea-surement of their performance to individualized rewards. As Deming(1986) suggested, they would tend to view the incentive plan as a lotteryand either attempt to manipulate it or eventually become victims of or-ganizationally induced helplessness (Ashforth, 1990). In the absence ofresearch, the above comparison must remain speculative.

Finally, a key to understanding linkages between individual- andunit-level performance may be found in extra-role behaviors. My discus-sion has included extra-roie behaviors within the construct of work per-formance. In a TQM context, extra-role performance may result in betterteamwork and cooperative efforts to continuously improve unit function-ing. As a result, I would expect that extra-role performance on the part ofindividuals would be associated with unit-level performance measures,especially over time. Research is necessary to test such possibilities.

Conclusion

This article attempts to incorporate TQM concepts and proposals intoa system-focused approach toward modeling work performance. Proposi-tions have been put forth that may help to further the understanding ofprocesses leading to the maximization of work performance. Various lit-eratures, including writings in TQM, have been integrated in an attemptto show the necessity and implications of dealing with system phenom-ena. In sum, the system has been viewed here as affecting performanceby indirectly enhancing aspects of the person, interacting with the personin terms of person/system fit, and constraining performance at lower hi-erarchical levels and in jobs lacking autonomy.

At the same time, person factors can have an impact on the nature ofsystems and work performance, especially at increasing hierarchical lev-els of organizations and in jobs characterized by autonomy. Thus, I havefocused on how and why both person and system factors must be consid-ered simultaneously when modeling the determinants of performance.Perhaps greater theoretical and empirical attention to the combined ef-fects of person and system factors would help management researchers todevelop a better understanding of performance issues. In doing so, man-agement theory and research might become more applicable to organi-zations in terms of helping them to enhance their performance.
