What is the Root Cause Analysis process?
Root Cause Analysis (RCA) is the process of investigating the root cause of an unexpected event or defects in a process or end product. This process aims to identify the root cause instead of treating the symptoms or even the intermediate causes.
Root Cause Analysis is not only applied to problems or unexpected issues that were found during a specific operation. However, RCA can also be applied to look for the root os a positive outcome.
How is Root Cause Analysis implemented?
Root Cause Analysis (RCA) helps workers finding the cause of a problem, looking for its origin, and ensure it is not repeated.
The RCA process can be defined in a small list of steps:
- Identify the problem clearly.
- Establish a timeline from the normal situation up to when the problem occurred.
- Distinguish between the root cause and other causal factors.
- Establish a causal graph between the root cause and the problem.
Each one of the 4 steps demands a specific inside procedure. Root Causes for a specific event are not always easy to find. Therefore, ensuring good tools to support workers on these operations is key to success.
