What is a root-cause analysis?
Root-cause analysis is a method of problem solving, used to identify the root cause of an issue such as an outage.
Four Steps of Root-Cause Analysis
- Identify the problem.
- Establish timeline from the normal situation up to the time the problem occurred.
- Distinguish between the root cause and other causal factors like using event correlation.
- Create a causal graph between the root cause and the issue.
