What is CAR (Causal Analysis and Resolution)?
The basic purpose of the CAR is to analyze all the problems, defects, and good practices/positive triggers in projects, perform a root cause analysis of the similar, identify respective corrective and preventive actions and track these to closure. The merits of CAR are that root causes are scientifically identified and their corrective and preventive actions are carried out. The CAR needs to be performed at project initiation, all phase and project ends and on a monthly basis. The Fishbone diagram is one of the ways you can do CAR.
