12. Evidence based management: What is it? 1. Some background

15. Evidence-based practice Central Premise: Decisions should be based on a combination of critical thinking and the ‘best available evidence‘.

16. Evidence? findings from scientific research, organizational facts & figures, benchmarking, best practices, professional experience 16

17. All managers base their decisions on ‘evidence’ 17

18. But…many managers pay little or no attention to the quality of the evidence they base their decisions on 18

19. Trust me, 20 years of management experience 19

20. SO... 20

21. Teach managers how to critically evaluate the trustworthiness of evidence from multiple sources and help them find ‘the best available’ evidence and help them find ‘the best available’ evidence

22. An example

26. Maslow, A.H. "A Theory of Human Motivation” An example

28. Professional experience and judgment Organizational data, facts and figures Stakeholders’ values and concerns Scientific research findings Ask Acquire Appraise Aggregate Apply Assess An example

29. Professional experience and judgment

30. Maslow, A.H. (1943). "A Theory of Human Motivation," Psychological Review 50(4) Wahba, M. A., & Bridwell, L. G. (1976). Maslow reconsidered: A review of research on the need hierarchy theory. Organizational Behavior and Human Performance, 15(2) Scientific research findings

31. How evidence-based are we (managers)? “I’ve never thought I need more evidence before making a decision; I know what needs to be done, we get on with it and we get results.”

32. 1. Incompetent people benefit more from feedback than highly competent people. 2. Task conflict improves work group performance while relational conflict harms it. 3. Encouraging employees to participate in decision making is more effective for improving organizational performance than setting performance goals. True (likely) or false (not likely)?

33. How evidence-based are we?  959 (US) + 626 (Dutch) HR professionals  35 statements, based on an extensive body of evidence  true / false / uncertain HR Professionals' beliefs about effective human resource practices: correspondence between research and practice, (Rynes et al, 2002, Sanders et al 2008)

34. Outcome: not better than random chance

35. EBP: Teach managers how to critically evaluate the trustworthiness of evidence from multiple sources and help them find ‘the best available’ evidence and help them find ‘the best available’ evidence

36. 2. Teaching EBP: Learning principles

37. Discuss with your neighbours: When it comes to teaching, what are important learning principles? 60595857565453525150494847464544434241403938373635343332313029282726252423222120191817161514131211109876543210

38. Learning principles 1.The brain needs time to get used to new things. Longer periods in between practice sessions lead to a longer overall retention. 2.Training program should include opportunities for practice, linked to real world situations. 3.The human brain seeks comfort in what it knows and is familiar with; addressing / confronting prior knowledge increases understanding (start from where the students are)

39. Learning principles 4.Higher order thinking only happens when people work on questions / problems / issues themselves. 5.Learning from failure is important for learning. Speculating and predicting before finding the correct answers helps people become adaptive learners / experts.

40. Teaching EBP =  Small groups  Problem based  Real life cases EBP starts with a practical question, not with an academic answer

41. 3. Teaching EBP: Curriculum

42.  Limitations of human judgment & common forms of cognitive bias  Retrieving & critically assessing experiential evidence  Retrieving & critically assessing organizational evidence (qualitative & quantitative)  Searching in research databases  Efficiently reading research articles  Critically appraising evidence from research  Weighing and aggregating evidence from multiple sources  Incorporating evidence into the decision making process  Different types of decisions and decision-making processes  Assessing the outcome of decisions made EBP: Curriculum

43. Professional experience and judgment Organizational data, facts and figures Stakeholders’ values and concerns Scientific research findings Ask Acquire Appraise Aggregate Apply Assess

44.  A critical and reflective attitude  Skills to distinguish trustworthy from less trustworthy evidence.  Thinking in terms of probabilities EBP: outcome

45. CAT: Critically Appraised Topic

46. A critically appraised topic (CAT) is a structured, short (2 – 5 pages max) summary of evidence on a topic of interest, focused around a practical problem or question..

47. CAT: structure 1) Background / context 2) Question (PICOC) 3) Search strategy 4) Results / evidence summary 5) Findings 6) Limitations 7) Recommendation

48. CAT: 3 hits 1. Small group (2-3), scientific evidence, list of topics 2. Individual, scientific evidence & theory, own topic 3. Individual, evidence from multiple sources, real life question / issue

49. CAT: examples  Is there a valid and reliable way to measure the productivity of knowledge workers?  To what extent will leadership training improve the effectiveness of leaders (e.g. managers, executives), what are the characteristics of effective leadership training programs?  What research evaluating the effects of 360-degree has been published in peer-reviewed scholarly journals in the past 10 years? Which of the variables that are expected to have an impact on the effectiveness of 360-degree feedback are most widely studied and what is known of their effect?

56. Discuss with your neighbours: What are the most common cognitive biases in management? (give an example) 60595857565453525150494847464544434241403938373635343332313029282726252423222120191817161514131211109876543210

57. We are predisposed to selectively search for or interpret information in ways that confirms our existing beliefs, expectations and assumptions, and ignore information to the contrary. In other words, we “see what we want to see” Confirmation bias

58. The amount of information increases faster than our ability to process it. Increase of information

60. War on Talent

62. 1. Pattern recognition 2. Confirmation-bias 3. Small numbers fallacy 4. Outcome bias 5. Halo effect 6. Authority-bias 7. Groupthink 8. Availability bias Biases

63. Assignment One of your best friends is trader on the stock exchange. He enthusiastically tells you he has analyzed a large number of financial and economic data and that he has discovered an interesting phenomenon: "The position of the Dow Jones index multiplied by the price of oil is two days ahead of the gold price!" In other words, if both the Dow Jones and the oil price go up, the price of gold will rise within a day.  Bias?  Critical questions?

64. We are predisposed to see order, pattern and causal relations in the world. Patternicity: The tendency to find meaningful patterns in both meaningful and meaningless noise. Bias: pattern recognition

65. Assignment Most people will prefer doctor B  Why? Bias?  Critical questions? doctor A doctor B Last operation: patient died on the operating table Last operation: patient recovered faster than expected

66. Outcome bias We are inclined to evaluate the quality of a decision (intervention, method) on the basis of its outcome. Bias: Outcome bias

67. The Asch Experiment

68. Nasa, Challenger

69. Groupthink: Groupthink is a psychological phenomenon that occurs within a group of people, in which the desire for harmony or conformity in the group results in an incorrect or irrational decision Bias: Groupthink

70. Bounded rationality System 1  Fast  Intuitive, associative  heuristics & biases System 2  Slow (lazy)  Deliberate, ‘reasoning’  Rational

71. Bounded rationality limbic system and brainstem (system 1) neo cortex (system 2)

73.  Critical attitude  ASK  Critically appraisal: research findings  Organizational evidence Teaching EBP: examples

80. Postgraduate Course Logic model

81. Postgraduate Course A logic model spells out the process by which a problem or intervention is expected to produce certain outcomes. In making expectations (its logic) explicit, a logic model helps identify the kind of evidence needed. Logic model

82.  Critical attitude  ASK  Critically appraisal: research findings  Organizational evidence 4. Teaching EBP: examples

86. Critical appraisal Always start with a practical question: -does it work? -how many employees …? -how do employees feel about …? How could we find out?

87. 87

88. Critical appraisal Amanda Burls: “I never tell them anything about randomization or blinding, I just ask: “How are you going to know? How would you test this if I would give you a half million dollars to test it?” And when they come up with a suggestion I say, “Alright, can you think of any reason you got the results showing it works, while in fact it doesn’t.” And they say, “Well, it could be this, it could be that” And then I say, “Ok, then redesign your study so it can’t be this,” and what they come up with are precisely those things: randomization and blinding.”

89. How trustworthy is this study?  Two studies, different designs  Studies with methodological flaws  Best available evidence (so what now?)  Online course! Critical appraisal
