What are the key steps in performing a 5-Why analysis to determine the root cause of recurring generator overheating issues?

The 5-Why analysis is a simple yet powerful problem-solving technique used to identify the root cause of a problem by repeatedly asking "Why?" Typically, asking "Why?" five times is sufficient to drill down to the core issue. To perform a 5-Why analysis for recurring generator overheating issues, the key steps are as follows: First, clearly define the problem: State the overheating issue precisely, including the specific generator, the operating conditions when overheating occurs, and the frequency of the problem. For instance, "Generator #3 stator winding overheats at loads above 80....
