cause-effect-chain-analysis

TRIZ Cause and Effect Chain Analysis (CECA) and Root Cause Analysis (RCA) — guides users through structured causal analysis to identify root causes, key disadvantages, and the contradictions behind them. Use this skill when the user mentions 'CECA', 'cause and effect chain', 'Ursache-Wirkungs-Analyse', 'Ursache-Wirkungs-Kette', 'root cause analysis', 'RCA', or wants to investigate why an engineering problem occurs, trace defects to their root causes, or derive contradictions from causal chains. For a failure investigation whose goal is an investigation plan, corrective actions and a final report rather than contradictions, use the root-cause-analysis skill instead.
