Root Cause Analysis

"Root cause analysis (RCA) is a method of problem-solving that tries to identify the root causes of faults or problems. RCA practice tries to solve problems by attempting to identify and correct the root causes of events, as opposed to simply addressing their symptoms. Focusing correction on root causes has the goal of preventing problem recurrence.


This is an example of a pump failure that leads to the unexpected shutdown of the pump. Doing RCA analysis by using the WHY TREE tool, in every step of analysis we asking why to find out the possible causes of that, normally we found 2-3 plausible causes. After evaluating and analysing those cases, we eliminate the causes on the basis of our evaluation and practical study and continue the process with the possible causes.
It is concluded at the end that the root cause of the problem is the misalignment during installation. After going deep into the problem asking WHY? The misalignment was not adequate we come to the problems that need to correct:
1. It is found that the tool and equipment used are inadequate, as there is a lack of annual equipment review and inspection.
2. There is also a lack of training for the person who is executing the alignment job.
3. Too much work pressure and less time lead to a decrease in the quality of the alignment process.


1. Proper inspection and review plan must be taken into account. It must include reviewing the tools and calibration process after a period of time ( 6 months or a year)
2. Training classes must be organized to train the manpower to follow the alignment steps incorrect way.
3. Job planning must be done to ensure that the right amount of time is given to execute a job (not less not much)
