What is RCA?

RCA : RCA is a method of problem solving and tries to identify the root causes of the problem or event

Different type of approaches of RCA:Safety based RCAProcess based RCAProduction based RCAFailure based RCASystem based RCA

General Principles of RCA

RCA must be performed Systematically. Problem will be having more than one root

cause. Purpose of identifying all solutions to the

problem. Analysis should be in a sequence of events. Root causes identification is depends on the

way in which the problem is defined.

Tracing a problem to its origin

Fixing symptoms of the problem : Problem will occur again and again

We need to follow RCA Determine what happened? Determine why it happened? What to do to reduce the likelihood that it will

happen again?Basic types of causes Physical causes Human causes Organizational causes

RCA Process

The process will be in 5 stepsStep 1 : Define the problem What do you see happening? What are the specific symptoms?Step 2: Collect Data What proof do you have that the problem

exists? How long has the problem existed? What is the impact of the problem?

RCA Process

Step 3: Identify possible causal factors What sequence of events leads to the

problem? What conditions allow the problem to occur? What other problems surround the

occurrence of the central problem?Step 4: Identify the root causes Why the causal factor does exist? What is the real reason the problem

occurred?

RCA Process

Step 5: Recommended and Implement Solutions What can you do to prevent the problem from

happening again? How will the solution be implemented? Who will be responsible for it? What are the risks of implementing the solution?
