In the Five-Why Method, which question focuses on measurable terms to assess the operability of preventive strategies?

• A. Why is there a lack of data?
• B. Why, in measurable terms, are the preventive strategies or newly developed solutions operable or inoperable?
• C. Why does the problem exist?
• D. Why do we need to change today?

Answer: (B)

The question tests turning proposed preventive actions into measurable criteria to judge whether they can actually be carried out. The best choice asks in measurable terms whether the preventive strategies or new solutions are operable or inoperable, which means you’re evaluating feasibility with concrete data, metrics, or thresholds. This helps ensure that the actions aren’t just theoretically sound but practically implementable and testable.

Lack of data is related to whether data exists to support analysis, but it doesn’t specifically address whether the preventive actions themselves can be executed and sustained. Asking why the problem exists focuses on root cause, not on whether solutions can be implemented. Asking why we need to change today centers on urgency or motivation, not on the practicality or measurability of the preventive measures.
