16 What is feedback?

17 How should useful feedback be handled?

18 Which source can provide feedback on a proposed solution?

19 What is continuous improvement?

20 Which activity supports continuous improvement?

21 A team is designing a mobile service to help patients schedule appointments. Which workflow representation would best clarify the sequence of user actions and system responses?

22 A workflow contains five approval stages, but most requests require only two. What is the most appropriate initial design response?

23 In a solution-development workflow, what is the main purpose of defining inputs and outputs for each activity?

24 A team notices that work frequently waits between research and prototyping. Which workflow improvement is most likely to address the problem?

25 A team wants to determine whether users can understand a new dashboard without assistance. Which validation method is most suitable?

26 A prototype receives positive comments from five team members, but none are target users. What is the main limitation of this validation?

27 A team is choosing between two onboarding designs and wants evidence about which one leads to more completed registrations. Which method is most appropriate?

28 A proposed solution appears desirable but requires expensive infrastructure. Which validation method should be prioritized before full development?

29 A survey shows that 80% of respondents like a proposed feature, but interviews reveal that many would not use it regularly. What should the team conclude?

30 A team tests a prototype with a fictional user profile that does not represent the intended audience. What is the most likely consequence?

31 During a usability test, nearly every participant fails at the same navigation step. What should the team do first?

32 Why should a testing team define success criteria before running a test?

33 A prototype passes functional checks but users take twice as long as expected to complete the main task. What does this result indicate?

34 A team has limited time and identifies ten possible improvements. Which approach best supports iterative refinement?

35 A team changes the interface, pricing, and target audience at the same time before retesting. Why is this approach problematic?

36 After each prototype cycle, a team records the change made, the evidence supporting it, and the observed result. What is the main benefit?

37 Users suggest adding many features, but several suggestions conflict with the primary goal of the product. How should the team respond?

38 A stakeholder requests a change based on one unusual incident, while repeated user tests show a different pattern. What is the best response?

39 Which practice helps prevent feedback from becoming a list of disconnected opinions?

40 A service meets its launch targets, but monthly data shows a gradual decline in successful task completion. What should the team do?

41 A team is designing a workflow for resolving customer billing disputes. Cases vary greatly in complexity, but every case must receive a compliance review. Which workflow structure best balances efficiency and control?

42 A proposed workflow reduces average completion time but increases handoffs from three to nine. Which analysis is most important before adoption?

43 In a workflow, activities A and B can occur in parallel, but activity C requires both outputs. If A takes 4 minutes and B takes 7 minutes, excluding coordination overhead, what is the minimum duration from starting A and B to completing C?

44 A service workflow has a high rate of rework because users submit incomplete information. Which redesign is most likely to address the root cause rather than its symptoms?

45 A prototype claims to reduce medication errors. Which validation design provides the strongest evidence while limiting confounding from differences between clinical units?

46 A validation study reports a statistically significant improvement, but the effect is smaller than the minimum benefit stakeholders consider worthwhile. What is the best interpretation?

47 A team validates a workflow only with expert users and observes excellent performance. Which threat remains most serious?

48 A team wants to validate whether a proposed intake process serves users with intermittent internet access. Which method is most appropriate initially?

49 A workflow passes every individual component test but fails when two automated services update the same record simultaneously. Which testing gap does this reveal?

50 A test suite shows 98% pass rate, but all failed tests concern a low-frequency safety exception. What should the team do first?

51 A workflow test produces inconsistent results because an external data service changes during each run. Which improvement most directly increases test reliability?

52 A new workflow improves average throughput but causes severe delays for the smallest 5% of cases. Which test metric best exposes this problem?

53 During iterative refinement, users request five changes, but engineering capacity permits only two. Which selection rule is most defensible?

54 A team makes several simultaneous workflow changes and observes improved outcomes. Why is this iteration difficult to learn from?

55 A refined solution performs better in a pilot but worsens after full deployment because users develop workarounds. Which refinement practice would best reduce this risk?

56 Users report that a workflow is confusing, but their proposed fix would increase compliance risk. What should the design team do?

57 Feedback comes primarily from highly engaged users, while less engaged users rarely respond. Which approach best reduces participation bias?

58 A stakeholder requests a feature that benefits one department but increases delays for all others. Which evidence should guide the decision?

59 A continuous-improvement program repeatedly optimizes processing speed, but customer complaints increase. Which corrective principle is most appropriate?

60 A workflow's performance improves for several months, then declines as demand and user behavior change. Which improvement mechanism is most robust?
