In the Measure phase, you discovered what’s really happening in your process. Now you need to identify why it’s happening, and determine the root cause(s). You need to manage by fact, though, so you must verify and validate your ideas about possible suspects. Jumping to conclusions is all too easy.

Carrying out the Analyze phase properly helps you determine the right solution(s) when you get to the Improve phase. Clearly, the extent of analysis required varies depending on the scope and nature of the problem you’re tackling, and, indeed, what your Measure activities have identified. Essentially, though, you’re analyzing the process and the data that the process produces.

Checking the possible causes of your problem using concrete data to verify your ideas is crucial. You may find the “usual suspects” aren’t guilty at all! Identifying and removing the root causes of a problem prevents it happening again.
