Specific problem and objective statements are critical to Six Sigma project success. Being as specific as possible sets up appropriate expectations on what is in-scope and what is out-of-scope
Creating strong problem statements lays a stable foundation that you can based on to create clear and specific Goals and Objectives, gives the team a beacon when they get overwhelmed with information, and reduces the chance of scope creep and misunderstanding.
Six Sigma projects are not everlasting initiatives, though the culture of improvement comes from Six Sigma is. This means your individual project needs a specific, challenging, but attainable goal. Once that goal is met, the project is concluded and you begin looking for a new problem to improve upon.
Scope creep occurs when teams look to make infinite perfections on a process, attempt to reach unrealistic goals, or begin to reach for processes or problems that are out of the original scope.
