A Root cause is a factor which hinders the smooth flow of the process and that causes the issue. The reoccurrence of the same issue over a period of time causes the problem.
So Root cause analysis is a collective term that describes a wide range of approaches, tools, and techniques used to uncover causes of the problems.
History of RCA
Root cause analysis (RCA) arose in the 1950s as a formal study by NASA to tackle the problems to its origins in the highly complex arena of rocket design, development and launch.
- RCA provides systematic process to examine the problems to the root causes, rather than rely on own or stakeholder’s assumption.
- RCA does not provide temporary quick solution, rather it take time to analyze but provide the permanent solution.
- RCA ensures the Quality Process and stakeholder’s satisfaction.
This technique has quite challenges as well, like
- Lack of knowledge of the people involved in finding the root cause.
- Lack of support from concerning personnel or team to find the answer to the question framed.
- Identify the problem(s) outcome from the process.
- Identify the stakeholders associated with the process.
- Assessment of the problem(s)by using various techniques like interviews, focus groups, and document or record reviews—to collect information on the causal factors leading to the problem.
- Identify the root causes of the problem by RCA technique like Fish-bone Diagram, Cause-and-effect Diagram.
- Take corrective Action and documented.
