Common Errors in Root Cause Analysis
Samir Desai
4 common errors in Root Cause Analysis (RCA):
1)
Scope: the scope of exercise is either too wide or too vague, for example delay in fabrication is chosen as the problem subjected to RCA rather than availability of manpower/material/design etc. This results in too many paths to follow.
2)
Formation of Team: often the people directly involved in the area of RCA are the only ones participating in the RCA. This leads to the tendency of you scratch my back, I'll scratch yours. It also results in barriers to bring in any fresh / innovative approach to problem solving.
3)
Data: RCA may be based on invalid data. The data provided to the team is accepted without much fuss, because to get valid data may end up in a supposed 'mission impossible'.
4)
Conviction: sometimes members are disheartened and dejected from the very first move, because they believe that no matter what the out come is going to be, there will be hardly any implementation efforts towards the corrective actions that will be suggested.
