When to Undertake RCA

1. Cause and Effect analysis (Ishikawa Diagram
or (C-E Analysis
) helps in finding possible causes by using Brainstorming
2. Pareto Analysis
helps in getting to the problems that have maximum impact as most likely candidates for RCA from C-E Analysis.
3. Controllability is one more factor which should be considered before going deep in RCA because factors which depend on envirnment and difficult to control may not be useful after RCA.
4. Another factor to be considered is knowledge level and instrumentation or such enabling factors whose absence may severely hamper chances of success in RCA.
