Understanding Six Sigma fundamentals, project selection, and establishing business case.
The Define phase establishes the foundation of any Lean Six Sigma project. It covers the basics and history of Six Sigma, voice of the customer/business/employee, project selection criteria, building business cases and project charters, developing project metrics, and understanding the Lean enterprise including the seven wastes and 5S methodology.

The Define Phase is the first and foundational stage of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology in Lean Six Sigma. This critical phase establishes the framework for the entire project by clearly identifying the problem, setting objectives, and aligning stakeholder expectations.
During the Define Phase, project teams focus on several key activities. First, they develop a Project Charter, which serves as a formal document outlining the business case, problem statement, project scope, goals, timeline, and team members. This charter acts as a contract between the team and organizational leadership.
The Voice of the Customer (VOC) is captured during this phase to understand customer requirements and expectations. Teams use various tools such as surveys, interviews, and focus groups to gather this valuable input. These customer needs are then translated into Critical to Quality (CTQ) requirements, which are measurable characteristics that must be met to achieve customer satisfaction.
Process mapping is another essential activity, where teams create high-level process maps like SIPOC (Suppliers, Inputs, Process, Outputs, Customers) diagrams. These visual representations help identify process boundaries and key stakeholders involved.
Teams also establish baseline metrics and define what success looks like for the project. Setting SMART goals (Specific, Measurable, Achievable, Relevant, Time-bound) ensures clarity and focus throughout the project lifecycle.
Stakeholder analysis is performed to identify all parties affected by the project and develop appropriate communication strategies. This helps ensure buy-in and support from key decision-makers.
The Define Phase concludes with a tollgate review, where project sponsors evaluate the work completed and approve progression to the Measure Phase. A well-executed Define Phase prevents scope creep, ensures resource alignment, and sets the project on a path toward successful completion. This foundational work is essential for achieving meaningful process improvements and delivering value to both customers and the organization.The Define Phase is the first and foundational stage of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology in Lean Six Sigma.
