Is vs. Is Not Analysis

Overview

The Is vs. Is Not analysis is a powerful problem-solving tool that makes the team think about the problem in more detail - specifically, what is and is not the problem. It helps the team focus its attention on the problems that the team is facing and not stray to areas that are not important. This tool helps the team focus on what is in and is not in scope.

You can use this tool when you are part of the way through a problem, and you are stuck and unsure what you are trying to solve or having difficulty determining what is important. You can also use this tool when planning a solution to decide what to include and what to exclude from the solution. This analysis documents where, what, when, and who are associated with the problem. This is a good technique to pinpoint a problem and narrow the search for a root cause.

To add the Is vs. Is Not a tool to your worksheet, click on Project and then select Is - Is Not Analysis.
