1. Evidence-Based Management
Teaching Managers to Make Better Decisions
Denise M. Rousseau
H.J. Heinz II University Professor of Organizational Behavior

2. What is Evidence-Based Management?
EBMgt is the practice of making organizational
decisions based upon conscientious use of
1. Science-based principles & knowledge
2. Valid & relevant facts
3. Critical thinking aided by decision supports
4. Ethical considerations (i.e., effects on stakeholders)

3. Why Should We and Our Students
Care about EBMgt?
 Better Decisions by Using Practices that Work (and
avoiding those that don’t!)
 Defensible Decisions that Stand Up to Scrutiny (using
best evidence and best process)
 Developing Expertise throughout a Career
(experience can be a poor teacher--bad habits!)
20 years of valid experience is different than 1 year of experience
repeated 20 times!

4. What does EBMgt Look Like?

5. Evidence-based Piloting?

6. 1. Use of Scientific Findings
 Chesley Sullenberger, USAIR pilot, has been a
visiting scholar at UC Berkeley’s Collaborative
for Catastrophic Risk Management since 2007
 Does research on how to make decisions to
maintain safety despite technological
complexity and crisis conditions

7. 2. Reliance on Reliable and Valid
Organizational Facts
 Has written and analyzed aviation accident
reports for over 20 years

8. 3. Mindful Decision Making:
Becoming Decision Aware
 Used Decision Aids to Support Good Decision: As Sully
considered what decision to make that day, he had his
copilot review and follow all checklists on board
relevant to crash landings
 Formal Education to Prime His Skills: Sully is a graduate
of the U.S. Air Force Academy and holds masters
degrees from both Purdue University in Industrial
Psychology and the University of Northern Colorado in
Public Administration

9. 4. Ethics and Responsibility to
Stakeholders
 The last person to leave the plane, Chesley
Sullenberger twice walked the plane’s aisle to
check all passengers were off
 Sully’s last act onboard was to grab the
passenger list. Used on-shore to verify rescue
of all passengers and crew

10. In Sullenberger’s Own Words…
“One way of looking at this might be that
for 42 years, I've been making small,
regular deposits in this bank of experience,
education and training.
And on January 15, the balance was sufficient
so that I could make a very large withdrawal.”

11. How Is Sullenberger’s Example
Relevant to Your Own Leadership
Development?

12. EBMgt is a means to
improve decision quality.
It’s a career, not a course.

13. The Zeitgeist
 Evidence-based practice movements abound in
medicine, education, and public policy
 Management research from psychology, engineering,
operations research (ETC.) yields 1000s of studies
annually
 Internet (scholar.google.com) gives ready access
 Innovative companies now hiring “chief evidence
officers”
 Public demands accountability (quality decisions that
are defensible)

14. EBMgt Overcomes Limits of Unaided Decisions
 Bounded Rationality  Critical Thinking
 The Small Numbers  Decision Supports
Problem of Individual
Experience  Research
• Large Ns > individual
 Prone to See Patterns experience
Even in Random Data • Controls reduce bias
The “Human” Problem Evidence-Based Practice

15. Three approaches
Push: teaching management principles based
upon a convergent body of research.
Pull: teaching students how to find, appraise
and apply the evidence from research and
their own organizations.
Process: focus on the context, steps in
decision making and ethics

16. Five Good EBMgt Habits
1. Get evidence into the conversation
2. Teach/Learn Evidence in Manager’s Area of
Practice
2a Teach/Learn Use of Scientific Evidence
2b Use Reliable and Valid Business
3. Learn to Gather Evidence
4. Become “Decision Aware”
5. Reflect on decision’s ethical implications

17. Five Good EBMgt Habits
#1 Get evidence into the conversation
Regularly ask “what’s the evidence…?”
Illustration- Discuss with your seatmates…
What’s a practice in your organization that you suspect might
not be NOT evidence-based?

18. Five Good EBMgt Habits
#2 Teach/Learn Evidence in Manager’s
Area of Practice
 Focus on Action Principles Where Science is Clear
(On-going Practice of A Professional Manager)
 Focus on Business Facts based on valid metrics
relevant to your decisions
(On-going Practice of Responsible & Transparent
Organization)

19. What is evidence?
 Evidence is not the same as „proof‟ or „hard facts‟
 ... can be
- so strong that no one doubts its correctness, or
- so weak that it is hardly convincing at all

20. Don’t confuse
 Evidence of effect (do!)
 Evidence of no effect (don‟t!)
 No evidence of effect (research!)

21. Five Good EBMgt Habits
#2a Teach/Learn Use of Scientific Evidence
 Focus on Action Principles Where Science is Clear
 Rely on Science-based Sources
 Example: Locke’s Handbook of Organizational Behavior
(access electronic copy for free)
 Peer-reviewed research, especially meta-analyses
Reduce dysfunctional variations in practice
Build effective routines, procedures, checklists

22. Five Good EBMgt Habits
#2a Teach/Learn Use of Scientific Evidence
Best Scientific Evidence is
 based on large N (sample size of
people/organizations)
 well-controlled studies with comparison groups
&/or longitudinal data
 peer-reviewed

23. Peer Reviewed Journals

24. Five Good EBMgt Habits
#2b Use Reliable and Valid Business Facts
Best Business Facts are
 large numbers sampled relative to population
(not single or isolated cases, e.g. %sales/# sales calls)
 linked to context (season, location, #users, etc.)
 provide key indicators for business decisions

25. Five Good EBMgt Habits
Illustration--Discuss with your seatmates…
 What indicators does your organization most
commonly use to make important decisions?
 Are these the “best business facts” you need to
make these decisions?
 What indicators would be more useful, if you
could get them??

26. Help Learner How to Interpret Business Facts
 # Medication errors in Unit 1 were 200% greater in 2011 than Unit 2’s. Is patient
safety worse in Unit 1? Depends on number of unsafe incidents divided by #
patients or # procedures—needs a control.
 Mike has w/10 subordinates & 20% turnover while Kim has 55 employees & 10%
turnover. Is retention better in one? Hard to determine. Small N’s have greater
bias and are more variable.
 McDonald’s stores average 300+% turnover/year. Does Mickey D. have a problem?
Depends on industry comparison and business strategy.
 Company A managers focus decisions on monthly cost, downtime and revenues.
Company B managers focus on service quality, employee retention and
profitability by customer category. So what? B’s more diverse performance
criteria can promote attention to longer-term and growth-oriented outcomes.
A’s narrower economic focus can promote shorter-term thinking.

27. Five Good EBMgt Habits
#3 Learn to Gather Evidence
 Structure and pose a managerial question
 Search for best available evidence (check out Google
Scholar or CEBMa website)
 Critically appraise information found
 Apply relevant case information to decision
 Write down the decision made, assumptions, and
expected outcomes
 Evaluate outcomes over time

28. Five Good EBMgt Habits
Gathering Evidence is a 5-step approach
1. Formulate an answerable question (PICOC)
2. Search for the best available evidence
3. Critical appraise the quality of the found evidence
4. Integrate the evidence with managerial expertise
and organizational concerns and apply
5. Monitor and evaluate the results

29. Getting the (Scientific) Evidence
What kind of evidence are we looking for?
 Studies with a design that best answers your
question
 Studies with the highest level of evidence

30. Levels of internal validity

31. Which study for which question?
Explanation

32. Levels of internal validity
It is shown that …
It is likely that …
There are signs
that …
Experts are of the
opinion that …

33. Practice Searching for Evidence
Using “Google Scholar”
Learning through play !
 Try all buttons
 Make lots of mistakes
 Have fun!
 Just do it!

34. Five Good EBMgt Habits
#4 Become “Decision Aware”
 Identify different kinds of decisions learners
face? What kinds of different approaches are
used to them? Why?
 How can you determine whether you made a
“good decision” when you cannot know the
outcome? (The answer to this question is what is
known as “decision quality”)

35. Five Good EBMgt Habits
“Decision Awareness” Promotes Decision Quality
 To manage decisions, know what decisions must be
made.
 Map out decisions that affect key outcomes.
 Who is responsible? (Are they prepared?)
 What information is required? (Will it be available when
needed?)

36. Five Good EBMgt Habits
Awareness Calls Attention to Decision Process.
Proper Processes Improve Decision Quality
 What is the process for making the decision?
 Different processes work better…
- for routine decisions (create validated checklists and action plans)
- for decisions with known unknowns (systematic sequence of
considerations)
- for decisions with unknown unknowns (pilot-tests and trial/
experiment)
 Decisions have an “aftermath” and a “pre-math” that a
good manager actively manages. Is the decision well-
managed? Help make it so.

37. Using Evidence Well Requires Your
Own Critical Judgment

38. Five Good EBMgt Habits
#5 Reflect on Decision’s Ethical
Implications
 Who are stakeholders for this decision?
 Possible effects?
 How might the decision be altered to optimize positive
stakeholder effects and reduce negative?

39. Five Good EBMgt Habits
Scientific Principles for Effective Teaching
 Set learning goals (2-5)
 Pre-test: where does learner stand on learning goal before course
 Build opportunities for practicing those learnings throughout
course (curriculum)
 Post-test: Measure progress on each learning goal and provide
feedback
 Feedback & Redesign: Use feedback to make course more
effective over time

Appendix: How to conduct a CAT

43. CAT: Critically Appraised Topic

44. CAT: Critically Appraised Topic
A Critically Appraised Topic (CAT) is a structured, short (3
pages max) summary of evidence on a topic of interest,
usually focused around a practical problem or question.
A CAT is like a “quick and dirty” version of a systematic
review, summarizing the best available research evidence on
a topic. Usually more than one study is included in a CAT.
Examples: http://www.cebma.org/presentations/

45. CAT: structure
1) Question (PICOC)
2) Background / context
3) Search strategy
4) Results / evidence summary
5) Comments (limitations)
6) Conclusion
7) Practical relevance
8) References

46. Asking the Right Question?

47. Asking the Right Question?
 Does team-building work?
 Does leadership development training work?
 Does management development improve the
performance of managers?
 Does employee participation prevent
resistance to change?
 Is 360 degree feedback effective?

Snowball method Building blocks method

61. Snowball method
Starting from one book or article, you search
for other literature on the same topic.
 Snowballing to older publications by finding out which
publications were used by the author (see bibliography of
book or article).
 Snowballing to more recent publications by finding out
how often that book or article has been
cited by other authors (see Web of
Knowledge or Google Scholar).
