RCA (Root Cause Analysis)
Root Cause Analysis (RCA) digs beneath symptoms to uncover the systemic drivers of quality issues. The goal is to prevent recurrence, not just to correct the immediate effect.
Popular RCA techniques
Teams combine tools such as the 5 Whys, Ishikawa diagrams, and fault tree analysis to reveal process weaknesses. Selecting the right technique depends on the complexity of the issue.
Linking RCA to action
Documenting RCA in KaizenQ
Within KaizenQ, inspectors and engineers record investigation notes, attach photos, and assign follow-up tasks. The shared history builds institutional knowledge for future problem solving.
Key takeaways
- RCA gets to the source of recurring issues.
- Findings should always link to corrective and preventive actions.
- Centralised documentation accelerates future investigations.
