Root Cause Corrective Action (RCCA) Overview
Corrective action (CA) is to remove the root cause and prevent a problem from ever happening again. The corrective action should correspond to the root cause identified earlier in order to eliminate the real root cause and prevent recurrence of the problem. Method such as brainstorming is recommended as it can help to select
