Root cause analysis (RCA) is a process used to identify the underlying cause of a problem or issue.
It is a key part of quality assurance and is used to identify and address the root cause of a problem, rather than just the symptoms.
This guide will provide an overview of RCA, including how to get started, best practices, and examples.
The first step in RCA is to identify the problem. This can be done by gathering data and information about the issue, such as customer complaints, reports, and feedback.
Once the problem has been identified, the next step is to determine the root cause. This can be done by asking questions such as: What caused the problem? What could have been done differently? What are the underlying factors that led to the issue?
Once the problem has been identified, the next step is to conduct an RCA. This can be done by using a variety of tools and techniques, such as brainstorming, cause and effect diagrams, and the 5 Whys.
Brainstorming is a great way to generate ideas and identify potential causes.
Cause and effect diagrams can help to identify the relationships between different factors that may have contributed to the issue.
The 5 Whys is a technique used to identify the root cause of a problem by asking “why” five times.
When conducting an RCA, it is important to keep the following best practices in mind:
Here are some examples of how RCA can be used in quality assurance:
