Voice of the customer, business case, project charter, project management tools, and analytical tools.
The Define phase establishes project foundations through Voice of the Customer analysis (customer identification, data collection, requirements definition using CTQ trees, QFD, SIPOC, and Kano model), building business cases and problem statements, developing project scope with SMART goals, and establishing performance measurements. It includes project management tools (Gantt charts, toll-gate reviews, WBS, RACI) and analytical tools used throughout DMAIC (affinity diagrams, tree diagrams, matrix diagrams, prioritization matrices, activity network diagrams, PDPC, and interrelationship digraphs).

The Define Phase is the first critical stage in a Lean Six Sigma Black Belt project, establishing the foundation for success. During this phase, the project team clearly articulates the business problem, project objectives, and desired outcomes. The primary goals include identifying customer requirements, understanding the current process, and establishing baseline metrics. Key activities involve developing a project charter that documents the business case, scope, timeline, and resource allocation. The team conducts stakeholder analysis to identify those affected by or contributing to the project. Voice of Customer (VoC) analysis is performed to capture customer needs and expectations, which are then translated into Critical-to-Quality (CTQ) characteristics. A high-level process map is created to visualize the current state and identify potential problem areas. The Define Phase also establishes project metrics, including the baseline performance and target improvement goals, typically measured using DMAIC methodology. Financial impact is assessed to justify project investment and establish success criteria. The team identifies project boundaries, constraints, and assumptions. Additionally, a communication plan is developed to keep stakeholders informed throughout the project lifecycle. Success in the Define Phase requires strong leadership sponsorship and cross-functional team collaboration. The Black Belt must ensure all team members understand the project's strategic importance and their roles. This phase typically concludes with a gate review where leadership approves proceeding to the Measure Phase. A well-executed Define Phase prevents scope creep, ensures organizational alignment, and significantly increases the probability of project success by establishing clear direction and measurable objectives.The Define Phase is the first critical stage in a Lean Six Sigma Black Belt project, establishing the foundation for success.
