✍️ Sample RCA Questions & Answers
1. Which RCA technique is particularly useful when causes are interrelated and cannot be explained by a single linear chain?
Causal Loop Diagrams model complex systems where causes and effects form feedback loops, making them ideal for interrelated systemic problems.
2. What is Root Cause Analysis?
Root Cause Analysis (RCA) is a systematic process for identifying the fundamental reasons for the occurrence of a problem or undesirable event. Its primary goal is to go beyond the immediate symptoms to discover the underlying causes, so that effective corrective actions can be implemented to prevent recurrence.
3. What is a 'poka-yoke' device used for in RCA prevention strategies?
Poka-yoke (mistake-proofing) devices are design features that make it impossible or very difficult for errors to occur, removing reliance on human vigilance.
4. What is a 'corrective action review board' (CARB) in the context of organizational RCA management?
A CARB is an internal management forum that provides oversight of corrective actions, ensuring they are appropriate, adequately resourced, and completed on time.
5. What is a 'corrective action closure criterion' in RCA?
Closure criteria define specific, measurable evidence (such as zero recurrences over 30 days) that must be demonstrated before a corrective action is formally closed.
6. What is the primary purpose of an RCA report?
An RCA report communicates what was found, why the problem occurred, and what actions will prevent recurrence, serving both organizational learning and accountability.
