An item-by-item acceptance checklist used before submitting a countermeasure. RCCM itself has three coexisting versions — 9 questions (REV4), 11 questions (REV6.3 body), and 10 questions (REV6.3 appendix) — differing in whether the Pareto step is split into two questions (tier-one and tier-two) and whether a point-of-impact 5-Why question is included.
In detail
The Countermeasure Checklist is an item-by-item acceptance checklist used before submitting a countermeasure. RCCM itself has three coexisting versions — 9 questions (REV4), 11 questions (REV6.3 body), and 10 questions (REV6.3 appendix). The 11-question version splits the Pareto step into a tier-one "where" question and a tier-two point-of-impact question, and adds a point-of-impact 5-Why question. It addresses the problem of inconsistent countermeasure quality and lack of unified acceptance standards, ensuring each countermeasure is systematically verified. Unlike general checklists, it emphasizes linkage with PD, root cause analysis, and quantification of countermeasure impact. The output is a list of accepted countermeasures.
Example in practice
A certain department developed countermeasures for customer complaints. Before submission, they used a countermeasure checklist to verify each item. They found that the countermeasures were not clearly linked to PD goals and lacked quantified impact. After revision, the countermeasures became more specific and measurable, and implementation results were significant. The checklist avoided the waste of ineffective countermeasures.
