HUMAN FACTORS/ERGONOMICS

Definition by the IEA (2000) “Ergonomics (or human factors) is the scientific discipline concerned with the understanding of the interactions among humans and other elements of a system, and the profession that applies theoretical principles, data and methods to design in order to optimize human well-being and overall system performance.”

WHAT IS HIGH-QUALITY ERGONOMICS?

Three core characteristics make us unique:

• Systems approach • Design-driven • Dual outcomes: well-being and performance

ACADEMY OF MANAGEMENT “We often take as given that an organization’s purpose to produce economic value; and, although economic value can often add to social value, sometimes it does not. This disjuncture raises the question of meaningfulness.”

“The meaningfulness of an organization is its expression of purpose, values or worth. It involves a sense of significance that goes beyond material success or profitability; rather, it highlights how organizations can play a larger and more positive role in the world.”

HUMAN FACTORS/ERGONOMICS

Definition for management scholars/practitioners “Ergonomics (or human factors) Human-centered design and management is the scientific discipline concerned with the understanding of the interactions among fit between humans and other elements of a system an organization, and the profession that applies theoretical principles, data and methods to design work and workplaces in order to optimize human well-being and overall system performance.”

MY CONCERN

De management world is interested in the links between work/workplace - wellbeing – performance, but does not see us! We must focus more on performance: 1. Because performance is in our definition 2. For delivering value for management (the ultimate decision makers) 3. By visiting management conferences

WHY IS THEORY IMPORTANT?

“There is nothing as practical as a good theory” (Lewin, 1943) “Bad theories are destroying good practice” (Groshal, 2005)

Lewin, K. (1943). Psychology and the process of group living. Journal of Social Psychology, 17, 113-132 Groshal, S. (2005). Bad management theories are destroying good management practices. Academy of Management Learning and Education, 4(1), 75-91 21

TOWARDS A NECESSITY THEORY OF ERGONOMICS

Managers “must have” ergonomics for high performance

NECESSITY THEORY OF ERGONOMICS

“Must have” = necessary

Ergonomics

Performance

23

CAUSAL THEORY: X  Y ( MEANS “CAUSES”)

X

Y

Sufficient cause: – X produces Y – X is sufficient but not necessary for Y (Additive logic) Necessary cause: – X allows Y – X is necessary but not sufficient for Y (Necessity logic)

“NECESSARY” IN PRACTICE “necessary” wordings in practice : • • • •

“must have” (versus “nice to have”). a “gotta have” “cannot without it” “critical success factor”

25

“NECESSARY” IN ACADEMIA “necessary” wording in academia: • X is needed for Y. • X is critical for Y. • X is crucial for Y. • X is essential for Y. • X is indispensable for Y. • X is a prerequisite for Y. • X is a requirement for Y. • X is condicio sine qua non for Y • X is a pre-condition for Y. • X allows Y. • X makes Y possible • There must be X to have Y. • Y requires X • Without X there cannot be Y

HIV is necessary but not sufficient for AIDS Intelligence is necessary but not sufficient for creativity (Guilford) Creativity is necessary but not sufficient for innovation (Amabile) Senior management commitment is necessary but not sufficient for successful organizational change



Etc. (Goertz’ first law: “for any research area one can find important necessary condition hypotheses.”)

33

NECESSITY THEORY OF ERGONOMICS

• Ergonomics is an “opportuniy enhancing practice” that complements “ability enhancing practices” (Selection and Training) and “motivation enhancing practices” (Leadership) • Each practice (including Ergonomics) is individually necessary for performance • Hence: having not enough Ergonomics is a bottleneck for reaching high performance, which cannot be compensated by the other practices • Hence: Ergonomics is not “nice to have” but “must have” 34

TAKE HOME SUGGESTIONS

1. Include always a performance aspect in all your activities – otherwise it is not ergonomics

2. Go to management conferences to better understand: – the needs, language and interests of managers – the value of ergonomics

3. Consider using necessity logic – to convince others that ergonomics is a “must” – to identify critical aspects that must be present for having desired outcomes

45

TOWARDS A NECESSITY THEORY OF ERGONOMICS

Ergonomics is a “must have” (necessary but not sufficient) for survival of companies and hapiness in the society
