What is the first phase of the Lean Six Sigma process?

The first phase of the Lean Six Sigma process is the Define phase. This phase is crucial because it sets the groundwork for the entire improvement project. During the Define phase, the focus is on identifying the problem that needs to be addressed, understanding the needs of the customers, and defining the project goals. This includes creating a clear project charter that outlines the problem statement, the objectives of the project, and the scope.

By establishing a comprehensive understanding of the issue at hand and the expectations of stakeholders, the Define phase ensures that all team members are aligned and that the subsequent phases—Measure, Analyze, Improve, and Control—are built on a solid foundation. This clarity is vital as it helps guide the team through the process and ultimately drives successful outcomes. Without a well-defined problem and objectives, any improvements made later in the process may be misguided or ineffective.
