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?
