Six Sigma: DEFINE – Tools, Charts and Diagrams

In the Define phase of Lean Six Sigma, the focus is on clearly defining the problem or opportunity for improvement and setting project goals and objectives. Various charts, diagrams, and tools are used to establish a common understanding of the project scope, objectives, and key metrics. Here are some commonly used ones:

  1. Project Charter: A document that outlines the purpose, scope, objectives, stakeholders, and deliverables of the Lean Six Sigma project. The project charter serves as a roadmap for the project team and provides formal authorization to proceed with the improvement initiative.
  2. SIPOC Diagram: SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. A SIPOC diagram provides a high-level overview of the process being analyzed, its inputs and outputs, and the key stakeholders involved. SIPOC diagrams help ensure that the project team has a clear understanding of the process boundaries and scope.
  3. Stakeholder Analysis: A technique used to identify and prioritize stakeholders who are affected by or have an interest in the outcome of the project. Stakeholder analysis helps ensure that the needs and expectations of all stakeholders are considered throughout the project.
  4. Voice of the Customer (VOC) Analysis: Techniques used to capture, analyze, and prioritize customer requirements and expectations. VOC analysis helps ensure that the project focuses on addressing customer needs and delivering value to the end-user.
  5. Problem Statement: A concise description of the problem or opportunity for improvement that the project aims to address. The problem statement should clearly define the scope of the project, the impact of the problem on the business or customers, and the desired outcomes.
  6. SMART Goals: SMART stands for Specific, Measurable, Achievable, Relevant, and Time-bound. SMART goals help ensure that project objectives are clear, achievable, and aligned with the overall strategic goals of the organization.
  7. Process Mapping (or Flowcharting): Visual representations of the steps in a process, used to identify inputs, outputs, activities, and decision points. Process maps help the project team understand the current state of the process and identify areas for improvement.
  8. Pareto Analysis: A technique used to prioritize problems or issues based on their frequency or impact. Pareto analysis helps focus improvement efforts on the most significant factors contributing to the problem.
  9. Team Charter: A document that outlines the purpose, goals, roles, responsibilities, and operating norms of the project team. The team charter helps ensure that team members are aligned and committed to achieving project success.

These charts, diagrams, and tools help establish a clear understanding of the problem or opportunity for improvement, define project goals and objectives, and set the stage for success in subsequent phases of the Lean Six Sigma methodology.
