HENRY FORD HEALTH SYSTEM 2
Introduction
Malcolm Baldrige National Quality Award winner of 2011, Henry Ford Health System
(HFHS) is an integrated and comprehensive health care system that offers large variety of
services. Headquartered in Detroit, Michigan, HFHS was established by Henry Ford, the auto
pioneer, in 1915. Initially it was Henry Ford Hospital (HFH) that expanded gradually to include
primary care units, wellness facility, retail shops, insurance agency and so on. There are
currently 140 sites and nine Business Units (BUs) of HFHS serving entire southeast Michigan. It
is a non-profit organization and offers uncompensated care to many. Highly qualified physicians
and specialists offer their services in HFHS.
HFHS is highly influenced by Deming principles of quality management. Dr. Deming
gave fourteen points for improving organizational and management system. He believed in
continuous improvement and quality outcomes. Some of his points are highly practiced in many
businesses including HFHS whereas some are not currently applied in HFHS.
This paper focuses on operational and management principles of HFHS. It will further
compare and contrast the HFHS’s principles with Deming’s principles. This paper will explore
Deming’s two principles with which HFHS is doing well; two of his principles that HFHS finds
difficult to implement, and three of his principles whose application in HFHS can effectively
improve it as an organization.
HENRY FORD HEALTH SYSTEM 3
Henry Ford Health System – A Comprehensive and Integrated Health System
In 1915, Henry Ford established not-for-profit Henry Ford Hospital (HFH) in Detroit,
Michigan. He encouraged research and education for continuous increase in employees’
knowledge and systems innovation. He innovatively divided HFH in two departments, inpatient
(IP) and outpatient (OP) but under single management. Gradually, HFH expanded to Henry Ford
Health System (HFHS) by integrating with three different departments. First department, Health
Alliance Plan (HAP) that offers low cost and high quality insurance plan; second is Behavioral
Health Services (BHS) that offers psychological services and care to patients; and third,
Community Care Services (CCS) that provides dialysis, hospice and retail services (Henry Ford
Health System [HFHS], 2011). Apart from the flagship HFH in Detroit, HFHS includes four
more hospitals, Henry Ford Macomb Hospital (HFMH) and HFMH- Warren Campus (HFMH-
WC) situated in Macomb; Henry Ford Wyandotte Hospital (HFWH) in Wyandotte; and Henry
Ford West Bloomfield Hospital (HFWBH) in Bloomfield that served southeast Michigan
(HFHS, 2011). This set of new hospitals was a mixture of organic and acquired properties.
HFHS has a separate department, Henry Ford Medical Group (HFMG) constituting 30
ambulatory services and 41 specialists (HFHS, 2011). Therefore, HFHS is a total of nine
different Business Units (BUs) that are distributed across 140 sites of southeast Michigan with
the workforce of more than 31,000 (HFHS, 2011) and an earning of annual revenue, $4.22
billion in 2010; net income, $21.5 million; and uncompensated care, $210 million (Connelly,
2012, p. 38). HFHS went a long way to increase its revenue from $2.1 billion in 2000 to $4.2
billion in 2010.
In Michigan, one of the most economically depressed states of the nation, HFHS
competes with many other health systems and insurance companies. Its market share is
HENRY FORD HEALTH SYSTEM 4
diversified because of its diversified service offerings. It holds 17.5% of IP (inpatient) market
share in tri-county regions of south east Michigan whereas its OP (outpatient) market share is
19% in the tri-county region. Its IP market share in entire southeast Michigan is 15.4% (HFHS,
2011). HFHS’s target markets are patients of hospitals and primary care, and purchasers of
health insurance (HAP) products.
HFHS was successful in crucial task of aligning mission, vision and values (MVV)
together with one single motive of giving its customers, The Henry Ford Experience (THFE)
(Connelly, 2012, p. 37). Its “mission is to improve human life through excellence in science and
art of health care and healing”. Vision is “to transform lives and communities through health and
wellness-one person at a time”. Values are “we serve our patients and communities through our
actions that always demonstrate. Each patient first, respect for people, high performance,
learning and continuous improvement, and social conscience” (HFHS, 2011). The MVV
(Mission, Vision and values) are supported by core competencies of HFHS. These core
competencies include “innovation, care coordination and collaboration/partnering” (HFHS,
2011). MVV are well coordinated with core competencies of HFHS through the support of seven
strategic pillars that include people, service, quality and safety, growth, research and education,
community, and finance. The information flow across all the pillars, progress measurement in
each pillar and strategic planning according to the progress are very well coordinated.
Changes in MVV and strategic initiatives in seven-pillar framework are under the
authority of Senior Leadership (SL). It is continuously involved with patient survey processes,
market research, focus groups, local and national benchmarking and research to understand the
customer needs and to influence potential customers (HFHS, 2011, p. 14). It studies specific
trends in complaints or suggestions and accordingly drafts Models For Improvement (MFI). It is
HENRY FORD HEALTH SYSTEM 5
also considering Baldrige Principle assessment since 2007 for designing strategic initiatives.
HFHS satisfies Baldrige criteria and also many of the requirements of Deming principles.
Is HFHS is doing well with improving every process and adopting new philosophies?
Dr. Deming, the TQM’s mentor, illustrated his fifth principle of management as
“Improve every process”. His perception was to improve every process of production and service
forever, and to continuously search for problems in every process. He believed that productivity
and efficiency of a process are inversely proportional to its cost; hence, with increased
productivity one can achieve decreased cost. Management should monitor this proportionality
and assign realistic goals instead of relying on arbitrary numbers and anecdotal data (Neave,
1990, p. 177).
HFHS constantly improves upon its processes of strategic planning, organizational
structure, performance improvement system, and models of improvement. It has designed a
robust culture inculcating “can-do” spirit among its employees and giving its customers a unique
“The Henry Ford Experience” (Henry Ford Financial Management [HFM], 2012, p. 37). One of
the seven-pillar framework of HFHS institution is “Quality and Safety”. HFHS has won many
awards for safety and quality, among them the recent ones are “Thomson Top 10 U.S., Quality
and Efficiency” award in 2009 and “Malcolm Baldrige Award for Quality” in 2011 (HFHS,
2011, p. 45). HFHS is one of the only four Baldrige award recipients in U.S. It is awarded a total
of $26.2 million from federal government along with other four healthcare institutes of Michigan
to complete the projects that will reduce health care cost and increase quality (Greene, June 15,
2012). HFHS robustly follows Deming’s illustrated quality chain reaction model (Fig. 1) for
reducing cost and improving quality. The CFO and Executive VP of HFHS, James Connelly
HENRY FORD HEALTH SYSTEM 6
believes, "Small changes make a big difference. In this environment, you have to watch your unit
cost carefully, which we have done"(HFM, 2012). HFHS is continuously chasing cost-effective
treatments and techniques with increased quality service for remaining competitive in the most
economically challenged state of U.S. Innovative techniques and treatment are invented but only
put into action after clinically testing it and doing proper market research (HFHS, 2011).
In HFHS, improvement decisions are solely based on comparative and competitive data
such as surveys; recommendations and complaints of patients; research and innovation
(incorporated in HFHS only after achieving success in its simulation centers), and focus groups.
Surveys are collected in person, via emails, phones, mails, and social media from patients and
customers. In order to make sure that patients are experiencing “The Henry Ford Experience”
(THFE), nurses invigilate the wards of hospitals on hourly basis to assure that none of the
patients has any complaints or difficulties (HFHS, 2011).
Major issues or complaints are discussed bimonthly with Senior Leadership (SL) in
“Employee Advisory Groups” meetings. Then they are presented in board meetings, which are
held every month. The Henry Ford Leadership System analyze all the data collection, feedbacks
and current trends and threats in the market and accordingly come to some changes in goals
leading to improve and enhance quality of service. The SL team has designed employee
engagement strategies; Lasting Impressions Framework; THFE reference pocket cards;
standardized service recovery (HEART- Hear, Empathize, Apologize, Respond and Thanks)
approach for its improvement in customer loyalty (HFHS, 2011).
Apart from improving every process, HFHS is doing well in adopting new philosophies
and creating innovations. Dr. Deming proves his second principle of management, “Adopt the
new philosophy”, by explaining how this world is changing and adopting with better
HENRY FORD HEALTH SYSTEM 7
performance and services. For sustainable success, change in system is very necessary, constant
improvement in process leading to increase in productivity and efficiency whereas decrease in
throughput time, lead time, setup time, or cost will always prove beneficial to the company. He
emphasizes on breaking the traditional barriers of “unwillingness to change, fear of failure and
unknown, people measuring productivity than improving it, etc.” and creating innovations for
betterment of society (Neave, 1990, p. 173).
HFHS’s one of the three core competencies is innovation therefore, breaking all the
barriers; it has placed many exemplary innovations in the field of health care. HFHS does
inventions and innovations for increasing productivity and efficiency. In 1998, HFH was the
first in state to offer genetic detection of breast cancer. In 2007, it has established 12,000 square
foot medical simulation center that allows physicians and students to enhance and test their
clinical skills in risk free environment. (HFM, 2012, p. 38). HFHS was the early adopter of EMR
(Electronic Medical Record), which is successfully leveraged presently by entire health care
industry. It was the first “mentor” hospital in nation-wide harm reduction campaign. Henry Ford
Medical Group (HFMG) performed the first robotic removal of cancerous prostate gland, which
revolutionized the prostate cancer treatment globally (HFHS, 2011). In 2011, HFHS collaborated
with Wayne State University Engineering studies and Detroit College of Creative studies in
order to establish the Henry Ford Health System Innovative Institute (HFHS-II) for research and
innovation in the field of health care (“Henry Ford”, n.d.). HFHS-II is working with Detroit
College and Wayne State University on projects of cancer detecting bra and miniature heart
pump (Miller, 2011). In the same year, HFHS won John M. Eisenberg patient safety and quality
award in innovation. It is one of the two hospitals that received Eisenberg award this year
(Angell, March 19, 2012).
HENRY FORD HEALTH SYSTEM 8
Several years ago, Henry Ford Hospital (HFH) implemented an innovative strategy of
inviting patients from other hospitals for transplantations and other critical surgeries. This
strategy proved very successful to HFH. It is one of its kinds to give its patients retreat like
experience in hospitals for agile healing and recovering process. Considering patients
convenience, it follows few new techniques of survey collection, like emails, social media, and
phone calls. Maximum of the HFHS hospitals take surveys in person by an innovative
mechanism that offers its patients to convey their complaints/compliments electronically via
televisions in their rooms, hospital leadership immediately respond to this feedback (HFHS,
2011). Henry Ford Health System is excelling in following some of the key principles of
Deming, such as improving every process and adopting new philosophies but it is difficult for
HFHS to incorporate “Permit pride of workmanship” and “Institute leadership”.
Why HFHS is finding it difficult to implement “Permit pride of workmanship” and
“Institute leadership”?
HFHS is not implementing Deming’s twelfth point, “Permit pride of workmanship”, in
its organizational structure. According to Deming, pride of workmanship should be given to
every worker by removing incentives and annual reviews because money will not encourage
them to do more work or rather do more quality work but instead it will make their growth
stagnant. Deming believes that performance appraisal is a bar to innovation because workers
pursue it as, if they are paid to do their instructed job then why will they contribute or create any
change or improvement in their work or the results of their work (Neave, 1990).
On the contrary, HFHS has mid-year performance reviews in July and annual
performance reviews in January. Compensation and rewards are aligned with the employee and
organizational performance. There are specific budgets allocated to different Business Units
HENRY FORD HEALTH SYSTEM 9
(BUs) depending on their performance on the goals of annual operating income targets. No
performance appraisals if the operating income targets are not met. The annual reviews have a
significant impact on base salaries and the employees are also compensated with bonus.
Depending on the employees’ designation various awards and compensations are given. Few
awards include Annual Incentive Plan (AIP) payment, Group Performance Award (GPA),
Employee of the Month awards, Celebration of Performance Milestone, Quality Expo Awards,
etc. Connelly, the CFO of the HFHS affirms that they have participated in pay-for-performance
initiatives that had significantly increased the employees’ performances (HFM, 2012). Today’s
competitive world and economic downturn are the key reasons for implicating incentive
programs because such programs establishes healthy competition in the company itself and also
tremendously encourages the employees to work hard and put their best efforts. Culminating
such programs might lead to increase in employee attrition.
Another key principle that HFHS has difficulty in adopting is Deming’s seventh
principle, “Institute Leadership”. Deming’s perception is that managers or supervisors’ job is not
merely supervision but they should help their team member to work efficiently. They should
provide special assistance to employees who require it; and take key decisions of improving
quality and enhancing employees’ work efforts. Their priority task is not to meet the goals or
prepare agendas but to find and solve key issues hindering quality of service or productivity of
employees. Managers and supervisor should take the ownership and accountability of the
defects, poor performance, and poor implication of techniques. Managers should appoint
employees on various projects depending their skill set, ability and interest in pursuing the
defined task (Neave, 1990).
HENRY FORD HEALTH SYSTEM 10
On the other hand, HFHS follows the preaching of John Kotter, a voice of Western
management style. He stated that leadership is about developing mission, vision and strategies
and appointing individuals that makes this vision and mission come true. According to him,
decision making of any change is an eight step long process that should be taken care by higher-
ranking leaders and not by managers. This eight step process include creating a sense of urgency,
putting together a team, creating a clear vision for the change, communicating this vision clearly
to the employees, encourage the team to make act on this vision, produce short-term results to
give them credibility, build momentum to act on new challenging problems, and adopt new
organizational culture (“World of Quality”, 2010).
In HFHS, managers play a role of middle management and higher authority takes
decisions. Managers’ task is to supervise the ongoing projects, conduct reviews of weekly
performance in staff meetings, emphasize on the decided goals of achievement and report their
higher authority about any change required or any issue to be resolved. There is a separate
division of decision making which includes 24-member system Board of Trustees (BOT) and
Senior Leadership (SL) team/ Performance Council (PC), which includes C-suites executives.
This division is accountable for mergers, acquisitions, mission, vision and values. They are also
responsible for strategic planning, new projects, and any change in goals and performance of the
employees. Management presents any major defect, change or issue during monthly meeting
with PC. If under ownership of PC, the issue is resolved or else BOT further considers it. In case
of emergency assistance, employees, volunteers, physicians and trainees can directly contact the
CEO of HFHS, Nancy Schlichting, via email (eNancy). She is available 24/7 for emergency
assistance. The patients can also communicate directly with her via television if they have any
issues or complaints. In case of change in policies, health care acts, mission, vision or goals of
HENRY FORD HEALTH SYSTEM 11
any team; the CEO posts a blog every week on the website (HFHS, 2011). New projects are
thoroughly studied by PC and BOT, they appoint a team for working on this process, creates a
clear vision and goals and the rest of the process is followed according to the Kotter’s eight-step
process (“World of Quality”, 2010). HFHS’s incentive program and leadership organization
proved to be successful according to the CFO and CEO of HFHS but there are few key areas
where HFHS should robustly implement some of the Deming principles.
Which three areas require implementing Deming principles for beneficial outcomes?
The first principle of Deming, “Constancy of purpose” illustrates constant improvement
of quality and service to help men live better mentally and materially. He encourages creating
long-term profitability plans, investing in right areas, improving constantly in goals to remain
competitive, sustaining in business and enhancing profitability (Neave, 1990).
In HFHS, the sustainability and profitability qualities of Deming’s principle are lacking.
Its net income dropped 64% in 2011, from $60.1 million in 2010 to $21.5 million in 2011
(Herman, April 6, 2012). It has millions of dollars invested in ongoing innovation projects and in
expansions of healthcare fields but with $21.5 million dollar net income, the CFO of HFHS is
finding difficult to carry out these projects. It has recently received grant from federal
government under the health reform act. This grant will be utilized in the ongoing projects but it
will not be sufficient for the completion of all the projects. In addition, the uncompensated care
(Fig. 2) is constantly increasing every year hence, it becomes a responsibility of HFHS to
successfully overcome this challenge for its sustainability in the healthcare market. Its IP market
share is 17.5% in the tri-county area and 15.4% in al southeast Michigan. Its four major
competitors also range from 10.5%-17.5% of IP market share in tri-county regions. Competition
is very crucial in healthcare and HFHS has to find the reasons for its less performance on the
HENRY FORD HEALTH SYSTEM 12
scale of market share. It has to increase annual revenues in order to expand HFHS’s profitability
and to assist un- and under insured people with uncompensated treatment.
There are nine Business Units (BU) of HFHS (Table. 1) and among them two BUs are
significantly underperforming in revenue generation. The HFMH- Warren campus, offering 203
beds provision, is generating 2 % of revenues. Another unit is BHS, which includes 7 clinics and
150 beds; and offers behavioral health services, generate 1 % of the revenues. On the other hand,
the flagship HFH accounts for 18 % of revenue and offers 803 beds. HFH lacks private rooms
and demonstrates a crowded environment, which significantly reduces customer satisfaction
(Fig. 3). HFHS should analyze the rationale behind such notable disparity among revenue
generations. If required it can reduce some clinics from BHS and invest its finance and the
working employees in HFH for gaining momentum in increasing customer satisfaction.
Current updates of HFHS illustrates that it is increasing efficiently in the direction of
overall improvement of HFHS as well as the society. It has closed its Warren Campus hospital
on March 31 after $70 million dollar loss in last five years. It has decided to establish a
rehabilitation center in the place of Warren hospital because market research indicates the
requirement of rehab in that area (“Henry Ford Macomb”, January 17, 2012). HFHS will open
its 32nd outpatient medical center in Bloomfield hills for the convenience of its customers
residing in Bloomfield. A substantial growth of this medical center in next five years is
forecasted by HFHS (Greene, February 06, 2012). HFHS has signed a merger agreement with
Detroit Institute of Ophthalmology (DIO) for enhancing research education in the field of
Ophthalmology by expanding DIO support services for visually impaired and blind
(PRNewswire, June 18, 2012). Therefore, considerable growth in market share is expected from
HENRY FORD HEALTH SYSTEM 13
HFHS by following Deming’s principle of constancy of purpose for profitability and
sustainability.
Deming’s sixth principle, “Institute training on job”, emphasizes on increasing skills of
employees required for the occupation and not their knowledge or education. Training is an
ongoing process that is required for the employees to learn skills for operating modern tools and
techniques. While training employees, leader must take into consideration various aspects of
teaching so that employees can easily learn and remember without extra efforts. Finance is a
major barrier for companies to institute training (Neave, 1990) but for HFHS, lack of proper
training resulted in violation of disability act, fine of $70,000, and requirement of mandatory
training for employees.
Gamble (February 06, 2012) reported that HFHS has settled a complaint with department
of Justice for the allegation that it failed to provide sign language interpreters to a deaf patient
and his deaf family. It has violated Disability Act and therefore, it will have to compensate this
violation by paying $70,000 to the family who issued this complaint; and by training the hospital
staff on the requirement of ADA, adopt specific policies and procedure to ensure assistance to
deaf and hard-of-hearing patients, appoint a corporate ADA administrator and ADA facilitators
at each hospital of HFHS.
Research shows that there is significant increase in employee turnover rates. Hospitals,
retail services and homecare services experience highest turnover in 2010. The Henry Ford
Medical Group (HFMG) physician engagement is 30-40% for overall satisfaction and that for
quality and care is 50%. It has increased constantly since 2004 but yet it is not satisfactory
(HFHS, 2011). High employee turnover and less employee engagement are two big challenges
for HFHS to incorporate training session. HFHS has to take some critical measures to reduce
HENRY FORD HEALTH SYSTEM 14
employee turnover, increase employee engagement especially of physicians, and to institute
proper training for communication skills and auxiliary services.
Deming’s eighth point, “Drive out fear”, describes about encouraging two-way
communication to enhance open communication between leaders and employees. It is important
to create an open and fearless environment in order to receive comments and compliments from
employees and their ideas for improvement (Neave, 1990).
In HFHS, two-way communication is encouraged but employees seem to be still not open
in their meetings with leaders. Open culture is required to receive innovative ideas from the
employees because they understand their customers better than leaders. Employees’ ideas should
be encouraged and appreciated. For improvement in this area, HFHS has started communication
training for leaders (HFHS, 2011). This will boost up their communication skills with their
employees and in return will boost the morale of employees to give their comments. Anonymous
surveys also can be a good option for encouraging employees to give their honest feedback and
improvement on ideas.
Conclusion
Henry Ford Health System is performing excellent in the field of healthcare and it will
continue to do so for upcoming many years. Its competitive advantages cover, not compromising
on quality and introducing innovative technologies for treatment and other purposes. It will have
to focus more on the marketing aspects in order to spread awareness about its core competencies
and to influence potential customers. Strategic and skillful planning for increasing revenue
generation and market share is required to strengthen the empire of HFHS.
