What are the best practices for scoping and defining a Lean Six Sigma project?

1 Understand the problem

The first step in any Lean Six Sigma project is to clearly understand the problem that needs to be solved. You should gather data and information from various sources, such as customer feedback, process maps, performance metrics, and stakeholder interviews. You should also use tools such as the SIPOC diagram (Supplier, Input, Process, Output, Customer) and the fishbone diagram (also known as the Ishikawa or cause-and-effect diagram) to identify the scope and root causes of the problem.

2 Define the goal

Once you have a clear understanding of the problem, you should define the goal of the project. What are the expected outcomes and benefits for the client and the customers? How will you measure and track the progress and success of the project? You should use the SMART criteria (Specific, Measurable, Achievable, Relevant, and Time-bound) to set a realistic and meaningful goal. You should also align the goal with the client's vision, mission, and strategy.

3 Form the team

A Lean Six Sigma project requires a cross-functional team of experts and stakeholders who can contribute to the analysis, design, and implementation of the solution. You should select the team members based on their skills, knowledge, experience, and availability. You should also assign roles and responsibilities to each team member, such as the project sponsor, the champion, the green belt, the black belt, and the team members. You should also establish the communication and collaboration channels and tools for the team.

4 Develop the charter

The final step in scoping and defining a Lean Six Sigma project is to develop the project charter. This is a document that summarizes the key elements of the project, such as the problem statement, the goal statement, the scope, the team, the timeline, the budget, the risks, and the assumptions. The project charter serves as a contract and a guide for the project team and the client. It should be approved and signed by the project sponsor and the champion before moving to the next phase of the project.
