Guide to Root Cause Analysis for PMI-ACP
What is Root Cause Analysis?
Root Cause Analysis (RCA) is a technique used to identify the underlying reason or 'root cause' of a problem or issue. It forms an integral part of problem-detection and resolution, especially within the realms of project management.
Why is Root Cause Analysis important?
In the PMI-ACP exam, understanding the concept of RCA is essential as it helps in not just identifying the symptoms of a problem, but also in discovering the fundamental issue causing those symptoms which, when dealt with, can prevent the problem from recurring.
How does Root Cause Analysis work?
Root Cause Analysis works by drilling down from the effect to the cause, using such techniques as '5 Why Analysis', 'Fishbone (Ishikawa) Diagram', or 'Fault Tree Analysis'. The ultimate goal is to identify the lowest-level cause that can be fixed, hence preventing the problem from happening again.
Exam Tips: Answering Questions on Root Cause Analysis
When answering questions on RCA in an exam, remember:
- Understand the difference between cause and effect.
- Check if the question is asking for immediate cause or root cause. In other words, look for the cause that, if fixed, will prevent the problem from recurring.
- Review the RCA techniques briefly and understand the basic principles behind each one. This will allow you to answer the questions more accurately.
- Don't rush. Carefully read and identify the key requirements of the question before giving your answer.
