CPM Analytical Decision Frameworks 2 — Questions and Answers
Question 1: A manager uses a decision matrix to evaluate three vendor options across five weighted criteria. What is the PRIMARY advantage of this approach over intuitive selection?
- It eliminates the need for stakeholder input
- It provides a systematic, transparent comparison that reduces cognitive bias (Correct answer)
- It guarantees the lowest-cost option will be selected
- It speeds up the decision by removing deliberation
Correct answer: It provides a systematic, transparent comparison that reduces cognitive bias
A weighted decision matrix structures multi-criteria comparisons transparently, reducing the influence of bias or personal preference on the outcome.
Question 2: In root cause analysis, the '5 Whys' technique is BEST suited for situations where:
- Multiple independent problems exist simultaneously
- A single chain of causation underlies the problem (Correct answer)
- Statistical data is unavailable
- The problem involves external stakeholders only
Correct answer: A single chain of causation underlies the problem
The 5 Whys works best when a problem has a single linear cause-and-effect chain rather than multiple interacting root causes.
Question 3: Which analytical tool is MOST appropriate when a manager needs to understand how changes in sales volume affect profitability under different cost assumptions?
- Gantt chart
- Sensitivity analysis (Correct answer)
- Affinity diagram
- RACI matrix
Correct answer: Sensitivity analysis
Sensitivity analysis tests how outcomes change when key variables like sales volume or cost assumptions are altered, revealing profitability risk.
Question 4: A manager applying bounded rationality theory recognizes that decision-makers typically:
- Process all available information before deciding
- Seek the optimal solution given unlimited cognitive resources
- Settle for a satisfactory solution due to cognitive and time limits (Correct answer)
- Delegate decisions to avoid personal accountability
Correct answer: Settle for a satisfactory solution due to cognitive and time limits
Herbert Simon's bounded rationality concept holds that decision-makers 'satisfice'—choosing a good-enough option—rather than optimizing, due to cognitive limits.
Question 5: During a strategic planning session, a manager draws a fishbone (Ishikawa) diagram. Which of the following BEST describes its purpose?
- Mapping project timelines and dependencies
- Categorizing potential causes of a problem for systematic analysis (Correct answer)
- Prioritizing tasks by urgency and importance
- Displaying financial variance between actual and budgeted costs
Correct answer: Categorizing potential causes of a problem for systematic analysis
A fishbone diagram visually organizes potential causes of a problem into categories (e.g., people, process, equipment), enabling structured root cause analysis.
Question 6: When constructing a payoff matrix for a competitive decision, a manager lists outcomes for each combination of own strategies and competitor responses. This approach is drawn from:
- Linear programming
- Game theory (Correct answer)
- Six Sigma DMAIC
- Force field analysis
Correct answer: Game theory
Game theory uses payoff matrices to model strategic interactions where the outcome of one party's decision depends on the choices of others.
Question 7: A manager reviewing a Pareto chart finds that 3 out of 15 defect types account for 78% of all defects. The CORRECT analytical conclusion is:
- All 15 defect types require equal remediation resources
- Eliminating those 3 defect types will likely yield the greatest quality improvement (Correct answer)
- The remaining 12 defects are negligible and can be ignored permanently
- The data sample is too small to draw any conclusions
Correct answer: Eliminating those 3 defect types will likely yield the greatest quality improvement
The Pareto principle (80/20 rule) indicates that concentrating improvement efforts on the vital few defect types will produce the most significant quality gains.
