Introduction

Negotiations are a critical aspect of modern life. From the board room to the family room, from local courts of justice to international tribunals, thousands of negotiations take place every day. Yet, many peo- ple see negotiations as a difIicult and painful process that they would like to avoid. While there are some new approaches, such as principled negotiation, that have been developed to improve the negotiation process, and theoretical frameworks like Evolution- ary Systems Design are available to guide in the structuring of negotiation problems, we are still early in our efforts to support negotiations with modern information technologies. This paper discusses the theoretical and practical compatibility of the princi- pled negotiation approach with the ESD framework and the use of computer-based group support systems

(GSS) as an attempt to move forward in improving negotiations.

The basic negotiation situation

Negotiation is a social process for resolving dis- putes, dealing with conflicts and managing differ- ences between people. Negotiation is distinct from other methods of dispute resolution in that it com- monly involves a face-to-face interaction between the parties in contention under conditions of some stress and duress. Not all meetings, however, can be char- acterized as a negotiation per se.

A meeting is characterized as a negotiation situation when differences in perceptions of the ends (goals) and means (methods/approaches) to the solu- tion of an issue leads to conflict and disputes. A negotiation situation is characterized by the bar- gaining process which is a complex pattern of sin- gular and joint actions such as requests, exchanges, questioning or challenges that goes through known stages of development.(Gulliver [ 11).

The basic observable target behaviors of interest in a negotiation are exchange transactions (offering and taking), evaluation (cognitive and affective), problem-solving, position taking, concession mak- ing and compromising, communicating ( talking, gesturing, signaling), face saving and relationship making. These are the range of visible behaviors that are part of the underlying processes of motiva- tion, decision making, communications, perception, and learning. The social sciences literatures have well documented the importance of these funda- mental behaviors in the initiation, development and completion of a negotiation (Rubin and Brown [2], Bazerman and Neale [3], Lewicki et al. [4]).

Motivated interdependence is a fundamental reason why people meet in a negotiation. Parties to a negotiation experience some degree of interde- pendence of needs. Whatever the sources and driv- ing factors, interdependence is founded on needs, real and perceived, such that one or both parties are seen to have something the other party needs to achieve an important goal.

In this theoretical scheme then, parties to a ne- gotiation meet to create the conditions and terms under which they can exchange various parts of their puzzles. For these reasons, they need to exchange information, clarifj~ understandings, offer compro- mises and make commitments -- essentially agree to the terms of the exchange. Motivating needs thus are the fundamental “engine” that drives a negotia- tion. Without them, there is no reason to meet and negotiate.

one’s negotiation situation brings about uncomfort- able reality testing that people do not always like. Fifth and last, people find negotiations difficult be- cause it is intense and difficult work. One has to be attentive at all times, maintain high levels of focus on content as well as process issues, often manage a team which may itself be in conflict, monitor the progress of the discussion, remember key details about standing agreements, be constantly analytical about the problem and the politics of the agreement, put in very long hours, deal with foreign languages, cultures and translators, o.ften be deprived of sleep, food and companionship and have to endure difficult conditions both in the negotiations as well as in liv- ing conditions.

Principled negotiation

Why negotiations are inherently difficult

Given the fact that negotiation is learned over a life time of repeated interactions, that it is a ubiqui- tous process and daily occurrence in most lives, one would think people would become comfortable and skilled at it. Curiously, the author’s dozen year ex- perience teaching negotiations to executives and business students shows the opposite tends to be true. Experiential evidence shows that people report ne- gotiations to be an inherently uncomfortable interac- tion with others. People tend to experience discom- fort, tension, higher levels of stress and often have fearful expectations about the process and outcomes of a negotiation meeting. What this suggests is that people have learned how to negotiate badly. In any case, they often find the processes and its outcome to be dissatisfying experiences. This dissatisfaction is the whole basis on which the principled and ethi- cal negotiation models are based. (Fisher, Ury, and Patton, [5]; Rusk [6])

Since negotiation is a human activity, there is great complexity in the subtle and overt behaviors that people exhibit in a negotiation. For these rea- sons, it is dficult to identify or claim a single method of negotiation to serve all people in all situations. People are too complex and interesting to be subject to such a mechanistic search for the “one best way to negotiate.” Human experience in early industry tried that “best way” optimal management philosophy only to discover that such idealist ap- proaches made no sense (Taylor [7]). People were not like machines, conditions were always changing, and problems were more and more difficult to solve. The same is true for negotiations. There is not “one best way to negotiate.” Halwever, this does not mean that any approach to negotiation is a good as any other, or that the negotiation process cannot be im- proved.

There are several good reasons for not liking to negotiate. First, the other party, their interests and style may not be known and there may be much am- biguity and uncertainty in the upcoming meeting. Secondly, since negotiation is about resolving differ- ences, conflict is an inherent part of the process. A third issue involves the question of identity and reputation. People’s egos are often tied into a nego- tiations and they fear losing face , looking “dumb”, losing self-esteem and confidence, or that their reputations will be hurt. A fourth issue that makes negotiation inherently difficult has to do with “reality testing.” Negotiation forces analysis of one’s situation, options, choices and the like. Clarifying

Recent developments in negotiation theory and practice have identified “principled negotiation” as an effective and improved way of resolving disputes (Fisher, Ury and Patton [5], Rusk, [[6]). This ap- proach is based on long ,practitioner experience in the law field and is presented essentially as a substi- tute for costly litigation methods to resolve disputes. The Fisher, Ury, and Patton book is a product of the Harvard Negotiation Project that is a major source of thinking, practical theorizing, and training in prin- cipled negotiation. The simplicity of the model and its parsimonious argume:nt have made it a major new approach to negotiations for a wide variety of negotiation situations. The following commentary is based on the principled negotiation model.

Principled negotiation is an approach that rests on three pillars. First, it argues that traditional ways of resolving disputes no longer work well for

239

people because they are more costly, tiresome, an- noying and not leading to good outcomes and serv- iceable agreements. This is especially true of law where litigation is very costly.

The second pillar argues that positional bar- gaining is the reason that negotiating the traditional way does not work. The traditional “give and take” approach is problematic for several reasons: people tend to lock into self-oriented defensive positions, either “hard’ or “soft,” leaving them less open to reasonable compromise. Because the outcomes are usually win-lose, they set up motives of retribution in return meetings. The resulting agreements are often unsatisfactory because they may be seen as unfair and therefore can be unstable. Positional bargaining is essentially adversarial; the main modes of behav- ior are pressure and threat oriented. Relationships are seen as more utilitarian and can be sacrificed for bargaining gain. Positional bargaining sends mixed messages about wanting to make agreements yet using approaches that seem to contradict original intentions. The result of positional bargaining then is generally lower levels of satisfaction with the process, structure and outcome of a negotiation.

The third and final pillar offers a the way to avoid positional bargaining by a strategy of “changing the game” to a more principled method that is designed to avoid the costs of positional bar- gaining. The principled approach fundamentally follows an integrative bargaining philosophy that has been identified early in the literature of problem solving (Lewicki et al. [4]; Filley, [S]). It is a ra- tional argument oriented approach that emphasizes reaching agreements on the merits of the arguments presented in bargaining and not by the perceived “rightness” of one’s case. It will yield to arguments that are “meritorious” but not yield to pressure. In this sense it is assertive in style insisting on the use of clear principles to establish the validity of a de- mand or a concession.

Four basic tenets of principled negotiation

The principled negotiation method rests on four tenets that aim to “change the game.” These points result from the authors’ experiences with negotia- tions, and are essentially recommendations that are behavioral in nature. Principled negotiation seeks to modify certain behavioral proclivities of people that lead to positional bargaining. The four tenets of the principled approach are to: (1) separate the people

porn the problem; (2) focus on interests and not po- sitions; (3) invent options for mutual gain; and (4)

insist on using objective criteria. An elaboration of these four principles follows.

Separating the people from the problems rests on the idea that participants have two fundamental interests in a negotiation: the issues or problems that need solving and the relationship between the par- ties. Often in the bargaining sessions, people make comments, or offer opinions and the like that can be seen as “attacks on a person.” Personal attacks, in- tentional or not, tend to force people on the defensive and back into positions. The relationship can be- come entangled with the problems. However main- taining a working relationship is critical to solving the problems. Relationship is the means to the ends of solving the issues of substance. Thus it is im- portant to create and keep a relationship going no matter how difficult the issues are. So the advice is to separate the relationship from the substantive is- sues and deal directiy with people problems when they arise. The skills for working with this first principle are human relations with a clear under- standing of conflict and emotions, the issues of per- ceptions and the importance of clear unambiguous communications.

The second tenet is to focus on interests and not positions. The theory here is that people tend to come to a negotiation with their own working theory of the situation. However, specific goals or positions may only serve immediate needs but do not serve the more fundamental interests that underlie peoples’ goals. Interests are founded in the concern for pro- tecting key principles and values. Desires, concerns, fears, and needs underlie the specific positions par- ties take. In addition, interests are multiple and not singular. Thus, there are possibilities for finding commonalties as a way to begin bargaining. Princi- pled negotiation maintains that behind opposed po- sitions there often lie shared and compatible interests as well as conflicting one. The challenge is to create a process that allows for the direct discovery and articulation of interests as the basis for the negotia- tion.

The third tenet of inventing options for mutual gain counters the tendency in positional bargaining of seeing only one or a few solutions to problems, that are usually the ones the positional bargainer suggests. The problem of limited options results from several behavioral tendencies: premature judgments before all the information is in; not lis- tening to the full story and reacting to selected is- sues; beliefs in and searches for a single “right” an- swer; assuming win-lose positions; restricting the sharing of information because of the belief that it leads to a loss of power; believing that the other

party’s problems are “their problems, not ours”; ego issues of wanting and demanding credit for the authorship of ideas (e.g. - if it is not my idea, I am not interested in it).

To avoid the problems of limited options that lead to positional bargaining, the principled method suggests that the invention of options should be separated from the act of judging the merits and choosing options. Further, the options should be creatively expanded so that many options are on the table and that single option solutions appear to be limiting and less realistic. Once the options are identified, defined and clarified, they can be re- viewed for commonalties where mutual gain can be had. The idea is to create an open atmosphere where the parties are not afraid to break frameworks and old habits in the search for novel, creative and better solutions to issues,

The last tenet of insisting on using objective criteria counters the positional bargaining tendency to force and insist on self-serving and willful criteria. The major fear behind all negotiations is the fear of “being taken.” People feel vulnerable and exposed when they have no basis for establishing the legiti- macy of the demand or offer of their negotiating partner. If criteria are accepted, individuals become more flexible in accepting different options and creative variations on solutions. Feeling cheated, on the other hand, leads to attitudes and actions that destabilize an agreement. If a person feels taken, they will withdraw from the working relationship because they do not consider the agreement as a le- gitimate one based on fair criteria. If the criteria are arrived at by an agreed upon process, then neither party will feel cheated and the bargaining process can proceed more smoothly. In the absence of objec- tive criteria, the negotiation proceeds on the basis of mistrust and willful forcing of issues. Thus the challenge here is to insist on ways of discovering and creating criteria for decision making that are jointly arrived at and are accepted as objective and therefore legitimate.

We can see then that principled negotiation is a philosophy and approach to negotiations that is co- herent, simple in expression and direct. Its compati- bility with ESD and GSS will be seen both in philo- sophical values and underlying assumptions about effective decision making, as well as in a reasonable application of GSS technology tools to the four ten- ets.

Evolutionary systems design Evolutionary systems design (Shakun [9-131) is

a modeling framework for policy making as a nego- tiation process, and negotiation as a policy making process. In Evolutionary Systems Design @SD), the viewpoint is taken that fundamentally reality is de- fined by relations between sets of elements, not sim- ply the sets of elements themselves (Shakun [9], Chapter 1). In ESD, the sets of elements consist of 1) vaZues or broadly stated desires; 2) operational goals, or concrete expressions of these values; 3) decisions, actions, or controls taken to achieve these goals; 4) criteria based on goals for evaluating the effectiveness of decisions; 5) individual preferences defined on criteria; and 6) coalition or group prefer- ences defined on individual preferences.

The relationship between these sets of ele- ments can be represented a:s two evolving hierarchies of relations. The Hierarchy 1 relation is a frame- work for evolving or defining the general problem in the sense of defining values to be delivered to group members in the form of operational goal variables by exercising control variables. The Hierarchy 2 rela- tion is a framework for finding a solution (the levels or particular values of the control and goal variables) to the evolved general problem at any stage. For a detailed discussion of ESD., see Shakun [9].

Group support systems The 1980’s saw the Idevelopment of computer

systems that aimed “to improve the process of group decision making by removing communication barri- ers, providing techniques for structuring decision analysis, and systematically directing the pattern, timing, or content of discussion” DeSanctis & Gal- lupe [ 151. While these systems were initially called Group Decision Support Systems (GDSS), many authors are now using the shorter name Group Sup- port Systems (GSS). Jessup and Valacich [16] use the term in the title of their recent book, and define GSS as “ . . .computer-based information systems used to support intellectual collaborative work.”

Other researchers interested in specifically sup- porting negotiation processes called their systems Negotiation Support Systems, or NSS. They see NSS as “...a special class of group support systems which emphasize bargaining, consensus seeking and conllict resolution” (Bui, Jelassi, & Shakun [17]). Recently, some authors have begun to argue that while negotiations may have some unique charac- teristics, all group processes contain elements of co- operation and conflict in varying degrees, and a

comprehensive support system must include tools several other aspects. In Table 1 below, some com- and techniques to support both these elements (Lewis mon GSS software modules are described, based on & Shakun [ 181; Lewis & Shakun [19]). This paper the Meeting Works TM package (tool module names argues that one approach to negotiations, principled are shown in italics). For thorough descriptions of negotiation, is especially compatible with the use of GSS packages, see Bostrom, Watson, & Kinney [20], GSS tools. and Jessup & Valacich [ 161.

GSS software

While there are significant differences between Key GSS Characteristics

the available GSS software packages, they also share many key features. They may differ in the specific modules included, the design of the user interface, the ability to create and use meeting agendas or scripts, the relative emphasis on oral discussion, and

In order to understand the impact a GSS may have on a negotiation, it may be helpful to describe a few key attributes that characterize most GSS. These are summarized in Table 2.

Table I: Typical GSS tools

Script Writer and Chauffeur

A GSS package needs tools to prepare for and manage meetings. This includes sup- port for defining the meeting procedures (ScriptWriter), and controlling execution of these tools during a meeting, as well as managing information about meeting partici- pants (Chauffeur).

Generate These tools generally allow for simultaneous and anonymous generation of written text. Typically, as participants enter ideas at their workstations and send these through the network to the chauffeur station, the ideas are collected on a list and then displayed at the front of the room through a video projector of some kind.

Organize These tools help a group systematically process raw lists of ideas, typically those created during a Generate step. Each step (discussing and reaching a common under- standing of the ideas, editing and rewording ideas, and organizing the ideas by grouping, sequencing, and building levels of analysis) is itself a complex task.

Evaluate Tool modules typically include voting, selecting, ranking, and rating using various numeric scales. One important feature is the preservation of participant anonymity. While the group will see detailed summaries of the results of an evaluation, the author of any specific rating or comment is not disclosed. This can result in more candid evalua- tions representing the true feelings of the group members.

Cross-Impact

Analysis:

There are times when a group needs to systematically examine the interaction of two sets of elements. For example, a group may want to consider the impacts from several alternative policies on a set of stakeholders. This module supports this kind of task.

MultipIe Criteria Analysis:

This tool allows the group to evaluate several alternatives at a time using explicit criteria. The participants can individually assign weights to each criterion to indicate their relative importance. Then, each participant rates how well each alternative meets each criterion. The software integrates individual evaluations into master tables and graphs that summarizes the results.

Table 2: Key characteristics of GSS

Problem vs. personal focus:

Anonymity:

Meeting structure:

Powerful evaluation tools:

Parallel input:

Documentation of the process:

GSS sessions typically take a problem solving approach to group tasks, rather than focusing on personalities, political power, or social relationships. Activities in a typical GSS session would include generating ideas, editing and organizing lists, ex- ploring relationships between ideas, and evaluating ideas.

Virtually all GSS tools include anonymity at various stages in the process. This is especially true for idea generation, and idea evaluation. T:his feature helps separate ideas from the persons who contribute them.

While many manual meetings lack any clear structure at all, the use of GSS tools automatically brings some structure to a group process. Th’e use of a GSS approach also tends to encourage a more careful consideration of the d.esign of a meeting, since tools must be chosen, and the relationship between steps defined.

GSS software typically includes the ability to rapidly combine evaluation data from the individual participants, and to present summary results in tables and graphs. This allows groups to use complex techniques such as multiple criteria analysis that would not likely be used without the computer support.

When entering ideas or evaluations, a GSS will typically allow the participants to all work at the same time, on their own computers. This allows the group to over- come production blocking that occurs when participants must wait for one speaker to finish before another can begin (as occurs in most unsupporhed groups).

A typical GSS tool can quickly print out a variety of reports documenting what has occurred in the meeting. Thus, participants have immediate written records in their own words, rather thank minutes filtered by someone else and distributed days or weeks later.

GSS consistency with principled negotia- tion

Now that we have described principled negotia- tion, ESD, and GSS separately, we can more directly address the issue of how ESD and GSS is consistent with, and supports principled negotiation. To do this we will refer back to the four major tenets described earlier.

viewpoints and interests in working side-by-side to find a rational solution to a common problem. When relatively high levels of conflict are expected, we have tended to think that these rational problem solving techniques are not as appropriate, but the proponents of principled negotiation tell us that problem solving approaches are highly relevant.

The anonymity feature of a GSS can have a strong impact on separating the people from the problem. In a typical ide,a generation session, par- ticipants privately enter their ideas at their own workstations. In one common approach, a master group list can be viewed Ion a shared screen at the front of the room (which becomes the “single text” for the discussion). Participants may be told that when they send their ideas to the shared list, they are making a gift of their idea to the group, and it is no longer their sole property. The shared screen creates a sort of neutral zone where parties are encouraged to be “hard on the problem” but by clearly separating ideas from the contributors, negotiators can still be “soft on the people.” It becomes possible to discuss and deal with the ideas on their merits, and greatly reduce the tendency to skew judgments based on knowledge of authorship, and to get involved with personal agendas and conflicts.

Separate the people from the problem

There are a number of ways a GSS approach is consistent with separating the people from the prob- lem. Group Support Systems were initially devel- oped to help solve problems and/or make decisions, and are at their core a problem-centered technology in the broadest sense. While it is not impossible that the tools could be used to address issues of personal relationships, virtually all the cases published to date describe meetings that center on the processing of problem/decision elements -- symptoms, underlying causes, goals, obstacles, solutions, criteria, etc. By agreeing to use a GSS, a group has already opened themselves to take more of a problem solving ap- proach than an adversarial approach. The raison d’etre of a GSS is to assist participants with differing

Fisher, Ury and Patton [5], pg. 32-36) empha- size the importance of clear communications when trying to separate the people from the problem. A GSS allows a group to capture important ideas in writing, rather than depending on oral communica- tions, which may introduce problems of speaking and hearing correctly, and participants “talking over” one another. With the writing approach of a GSS environment, a participant can take the time to carefully edit a statement before submitting it. They have a cooling off period where they can read their idea and ask “do I really mean this” before sending it on to the shared screen. With the use of networked computers, all participants can essentially “talk at once” as they type their ideas. Some GSS software, like MeetingWorks, includes tools that support the joint editing of a list of ideas, which can help clarify and reword the ideas on an initial list. The overall effect may well be to improve the accuracy of com- munications in the group and increase the chance of reaching an appropriate negotiated settlement.

used to generate interests by asking the question “why do you want that?” The generate tool could be used to allow the participants to type in their answer to this question for each of the original positions they submitted. This has the effect of making the rea- soning structure explicit and open to discussion. Thus, the GSS makes it easier to develop an organ- ized list of interests for each of the parties. In addi-. tion, one of the evaluation tools could be used for participants to indicate the relative importance of their various interests (e.g., “I am strongly interested in maintaining career flexibility, but only mildly interested in achieving recognition from my peers”) .

Invent options for mutual gain

Most GSS developers recommend the use of a trained facilitator to help run sessions. One of the main reasons this person is needed is to handle the “people problems” that occur in group meetings. For example, Clawson, Bostrom, & Anson [21] worked with 50 facilitators to identify critical facilitator be- haviors in computer-supported environments such as: . actively builds rapport and relationships . creates an open, positive environment . manages conflict and negative emotion . encourages and supports multiple perspectives

For this part of the principled negotiation proc- ess, Fisher, Ury, and Patton recommend using vari- ous brainstorm techniques ([5], pg. 60-68). Idea generation is one of the things a GSS supports best. While GSS tools make it very easy for a group to quickly develop lists of options, it would be the re- sponsibility of the facilitator to correctly frame the question so that appropriate options were generated, options that do result in mutual gain. This leads to the separation of option creation from the evaluation of options, which is an import principle advocated by Fisher, Ury, and Patton. The anonymity of the gen- eration process, along with the parallel production of ideas, and the automatic recording of ideas are ad- vantages the GSS approach has over a manual brain- storm session.

Insist on using objective criteria

Thus, the use of a process facilitator is fully con- sistent with the recommendation that in principled negotiation, one should “separate the relationship from the substance; deal directly with the people problem” (Fisher, Ury, and Patton [5], pg. 21).

Focus on interests, not positions

GSS tools do not in themselves provide a focus on interests rather than positions in negotiations. However, GSS tools can be helpful in achieving this focus by they way they are used. For example, a mediator could use an idea generation tool to ask the parties to list what they hope to gain from the nego- tiation. The initial answers are likely to consist of detailed positions rather than general principles and interests. The mediator could proceed to discuss the difference between general interests and detailed positions. Then, as recommended by Fisher, Ury, and Patton ([5], pg. 44) the list of positions could be

This is a critical aspect of principled negotia- tion. Indeed, according to Fisher, Ury, and Patton “the more you bring standards of fairness, efficiency, or scientific merit to bear on your particular prob- lem, the more likely you are to produce a final pack- age that is wise and fair” ([5], pg. 83). The use of objective criteria in selecting solution options in a negotiation resonates especially well with the ap- proach of multiple criteria analysis, which is in- cluded in some GSS software as described elsewhere (Lewis & Shalom [IS]). In the this approach, crite- ria are explicitly defined; in this case based on the parties’ interests identified earlier. The criteria are weighted to indicate relative importance, and then used to evaluate the solution options generated in the previous step. While this can be a complex and cumbersome technique that takes too long in a man- ual setting, the use of computers and GSS makes it relatively easy and certainly fast. A GSS also pro- vides sophisticated summaries and analysis of re-

sults, making it easy to understand which options are preferred, and why, and where there is agreement and disagreement. The results can serve as a basis for re-structuring the negotiation, and the further invention and/or consolidation of options.

Quality of decision

Potential additional benefits of GSS Besides the overall compatibility of GSS with

principled negotiation, there are other important reasons that it may be useful to adopt a GSS ap- proach to negotiations. In 15 years of research on GSS, a number of general benefits have been identi- fied which may also be realized in negotiation ses- sions. Some of the more significant include the fol- lowing.

As has been true for other variables, the results are different for field and lab studies. Of sixteen lab studies, most showed no significant difference (ten of the sixteen), while five showed GSS to result in a better decision, and one showed the manual method to result in a better decision. However, in seven out of eight field studies, GSS groups produced better decisions than manual groups, and in the eighth case, there was no significant difference (Pervan [22]). For negotiations to be truly successful, the parties must feel that a good and fair agreement was reached. If GSS can help improve the quality of the decisions, it may be easier to successfully conclude the negotiation.

User satisfaction Equality of participation

Pervan [22] has summarized the results of 37 lab and field studies that measured user satisfaction. Nineteen out of twenty-one field studies showed user satisfaction to be higher for GSS, and in the other two cases there was no significant difference. In no case was user satisfaction lower for GSS. He found that the results for lab studies were quite mixed. Across the three types of satisfaction, nine out of 16 lab studies showed no difference between user satis- faction for GSS or non-GSS, while four were more positive for GSS and three were less positive. The strong showing in field studies may indicate that negotiators could find greater satisfaction from par- ticipating parties if they were able to use GSS tools.

One of the supposed impacts of GSS use is that more of the participants will actually contribute to the meeting, and that it is l~ess likely that the meeting will be dominated by a few members. Of the six studies that compared GSS to manual meetings on this dimension, four reported greater equality of par- ticipation in GSS sessions, while two reported no significant difference (Pervan [22]). If parties to a negotiation are to “buy in” to the result, they must feel that their concerns were taken into account. By encouraging more equal participation in the nego- tiation process, a GSS may improve commitment to the result.

Meeting effectiveness GSS and evolutionaqy systems design

Pervan [22] summarizes seventeen studies that measured perceived effectiveness, where sixteen studies were in the field and one in the lab. Of these seventeen studies, fifteen reported greater effective- ness for GSS meetings, while two showed no signifi- cant difference. No study reported lower effective- ness for GSS sessions. Again, if negotiatiors are hoping to increase the effectiveness of their sessions, GSS might be a significant help.

Meeting efficiency

Meeting efficiency is concerned with time and cost savings that might accrue from the use of a GSS. All ten of the studies that measured efficiency concluded that GSS groups were more efficient than non-GSS groups (Pervan [22]). Many negotiations are felt to drag on and take an inordinate amount of time. GSS may help groups get through the nego- tiation process faster.

The issue of the integration of a theoretical framework like ESD and a GSS like MeetingWorks has been discussed thoroughly in Lewis & Shakun, 1996. To summarize briefly, while a growing body of research now exists indicating that the use of a GSS may help overcome some of the known prob- lems with group decision making, so far there are few examples of GSS’s that implement strong con- ceptual frameworks. Whib: ESD provides an appro- priate theoretical framework for negotiations, a GSS like MeetingWorks can slerve to operationalize the ESD concepts. Without the support of a GSS, it can be complex and time-consuming to follow the ESD framework. Conceptual frameworks that lack support tools to implement their concepts may never be used. On the other hand, using GSS toolkits without guiding frameworks can generate a great deal of activity without addressing the problem or decision in a systematic or effective manner. It is hoped that the combination of conceptual framework and GSS

may allow groups to use more sophisticated ap- proaches to group problem solving and decision making, without overwhelming the participants with the difficulty and complexity of the process, as might happen with a manual approach. The combination of a theoretical framework like Evolutionary Systems Design and a GSS like MeetingWorks may provide a powerful new approach for improving the quality both of the group process and the final negotiated settlement.

Principled negotiation and evolutionary systems design

While ESD is a theoretical framework with firm roots in operations research and decision science, principled negotiation is an approach or set of be- havioral recommendations based on practitioner ex- perience with actual negotiation situations. How- ever, the two are quite compatible and lead to similar approaches to negotiations despite superficial differ- ences that appear to be primarily semantic in nature. The relationship can be examined by reference to the four components to the principled negotiation ap- proach.

Separate the people from the problem

Both ESD and principled negotiation approach negotiations from a problem solving perspective. ESD provides a conceptual framework that can be used to support negotiation problem evolution and solution. The general approach is to structure the negotiation problem in such a way that is may be possible to find a single solution that has the highest utility for all parties. Where conflict is present, i.e. where no single solution has the highest utility for all parties, ESD advocates techniques for expansion of the goal target and the feasible set of solution al- ternatives. Clearly, ESD distinguishes the problem from the people and relationships involved, and tends to keep the focus of concern on the problem.

Focus on interests and not positions

As discussed earlier, interests involve the key principles and values of the parties to a negotiation, including their desires, concerns, fears, and needs. A position is really one possible way to deliver a set of interests to the parties - one possible negotiation solution. Specific positions may seem to serve im- mediate needs, but do not necessarily serve the more fundamental interests that underlie peoples’ goals.

In the ESD framework, Hierarchy 1 focuses on representing a negotiation problem in terms of the

Proceedings of the 29th Annual Hawaii International Conference on System Sciences - 1996

relationship between values, goal variables, and control variables. This initial focus on values and goal variables in ESD is the equivalent of focusing on interests in principled negotiation. In Hierarchy 2, specific levels are defined for sets of control and goal variables; each such set can be considered a position. It is important to note that these positions are not considered until the construction of Hierar- chy 1 has been completed.

ESD goes beyond the enumeration of values and goal variables as described in principled negotiation, and looks at their relationship, and well at their fur- ther relationship to control variables. So, in the ESD approach, the participants would be asked to define the fundamental values they are trying to. achieve through the negotiation, and then to move on to more specific goals and possible controls that might deliver the values. ESD provides a clearly and com- pletely elaborated framework that can be used to structure the negotiation problem. This has the ef- fect of keeping participants from prematurely lock- ing in on positions, as is advocated in principled negotiation.

Invent options for mutual gain

ESD encourages the invention of options by a process of problem evolution and restructuring. Once the initial set of values, goal variables, and control variables have been identified, heuristics can be used to generate potential solution options. For example, participants can be systematically prompted with questions such as “given the set of values and goals that have already been identified, are there any other control variables that could de- liver any of the values?” Another way of generating options would be to focus on the levels of the con- trols. Participants could produced new options by generating internally consistent sets of control vari- ables with their levels specified.

Insist on using objective criteria

The use of objective criteria is an explicit part of the ESD framework. More specifically, a multiple criteria decision making (MCDM) approach is advo- cated for most negotiation situations. Hierarchy 2 includes the definition of criteria and the goals/criteria relationship as an integral part of the ESD process. Even social-emotional aspects of a negotiation can be included in the ESD approach (Faure, Le Dong, and Shakun [23]).

The relationships between principled negotia- tion, evolutionary systems design, and Meeting- Works GSS are summarized in the following table:

Example of GSS support for negotiation Lewis & Shakun [18], have described a hypo-

thetical meeting script or agenda that implemented the ESD framework using MeetingWorks. Here we will describe how this script is consistent with the tenets of principled negotiation, resulting in a syn- ergy between ESD, GSS, and. principled negotiation. The case assumes that a company is contemplating a

purchase of a fleet of automobiles for use by their sales stafI in the field. The group includes repre- sentatives from purchasing, sales, maintenance, the legal department, etc. They do not initially agree on the appropriate vehicle tal be purchased, and must negotiate an agreement. The script outline (slightly modified) is as follows:

Consistency with tenet #l

The first tenet of principled negotiation involves separating the people from the problem. In the ex- ample case, this is done by focusing the session on the structure and content of the fleet purchase prob- lem, rather than on the persons involved in the ne- gotiation. In addition, several steps make use of the anonymity feature of MeetingWorks for idea gen- eration (A. I., A.3, A.7) and evaluation (B.2). The steps that involve discussing and organizing the written ideas (A.2, A.4, A.8) use the Organize tool to improve the communications between the parties, and keep the focus on the problem rather than the participants. A skill GSS facilitator will also be helpful in handling issues of personal relationship during the session.

Consistency with tenet #2

The second tenet of principled negotiation holds that to be successful, a negotiation should focus on the interests of the parties, and not on their positions. In our case example, it is immediately seen that the underlying interests, or values, of the participants are the starting point for the negotiation, and that posi- tions (in this case support for specific vehicles) are not addressed until much later. If participants do come to a meeting with firm positions already de- fined, the facilitator could easily modify the script to incorporate some advice given by Fisher, Ury, and Patton [5]. In such an event, two questions would be posed to the group “why do you support the purchase of a specific vehicle - what do you gain from it?” and “why do you oppose the purchase of other vehicles - what do you lose?’ The Generate tool would be used to gather the responses, which will generally be in the form of the interests underlying the various posi- tions, and will help re-focus the group.

Consistency with tenet #3

The third tenet of principled negotiation rec- ommends that groups invent options for mutual gain. In the fleet purchase case, this would be interpreted to mean the group should cast a wide net when looking for vehicles to purchase, as well as other aspects such as the various options that could be in- cluded with a particular vehicle (like power steering, air conditioning, anti-lock brakes, air bags, etc.). It could also include alternative financing schemes, differing maintenance schedules. various insurance policies, additional uses for the vehicles, and any other factor that might have an impact on the inter- ests of the parties involved in the purchase.

The example meeting agenda includes this kind of activity in steps A.5 and A.9 where participants use the Cross-Impact tool to identify instances where a member might object to a certain value being de- livered by a given goal, or a goal being delivered by a certain alternative. This has the effect of identify- ing items where there are strong objection (no mu- tual gain), and encouraging the generation of addi- tional goals and/or alternatives (controls) to try and deliver the underlying value (interest). In addition, step A.7 and A.8 are specifically designed to encour- age the generation of a whole number of options (alternative vehicles), rather than just the few that participants might have brought with them at the beginning of the meeting.

Consistency with tenet #4

Tenet four recommends the use of objective cri- teria. This is an essential part of ESD, and is sup- ported by several Meet&Works tools. In our ex- ample case, there is a progression from values (quite broad and abstract), through goals (more specific and concrete), and finally to criteria (correctly for- mulated for use in evaluation). The development and application of the criteria is the major focus of Hierarchy 2, as seen in steps B.l and B.2. The cen- tral purpose of the Multiple Criteria Analysis tool is to support the use of criteria in evaluating various options, rather than a contest of wills and power. This can be a complex and difficult task to handle manually, but the computer can quickly and easily combine the inputs of multiple participants using multiple criteria to evaluate multiple options.

Conclusion

We have argued that the negotiation process is an important but difficult group activity that is in need of improvement and support. Principled nego- tiation is one approach to improving the negotiation process, and Evolutionary Systems Design is a pow- erful framework for structuring the negotiation situation. Group Support Systems, such as Meet- ingWorks appear to be compatible with the fiame- work of ESD and the four basic tenets of principled negotiation, and may offer several key benefits in- cluding improved user satisfaction, increased effi- ciency and effectiveness, better quality settlements, and more equal participation in the negotiation proc- ess.

However, it will now be important to move be- yond the theoretical arguments for compatibility and potential benefits to actual tests of these ideas. We

would hope that GSS researchers and practitioners would collaborate with mediators and others inter- ested in principled negotiation to conduct field stud- ies that can determine whether these potential bene- tits will in fact be realized. There are sure to be im- portant limitations and barriers to the use of GSS for

negotiations. We need to know what these are so that we may discover ways in which group support systems can be expanded or modified to better sup- port negotiation situations.
