Define is one of the five DMAIC phases in Six Sigma that a project must go through. In the Define phase, the problem statement is defined in a project charter.

DMAIC
The DMAIC roadmap is a structured approach in 5 phases for executing Lean Six Sigma projects. Its goal is to optimize an existing process.
The DMAIC roadmap is the most crucial success factor in Lean Six Sigma. The five phases build systematically upon each other and provide a clear guiding framework.
CTQ
In Six Sigma, CTQs (short for Critical-to-Quality) are understood as critical quality attributes necessary to achieve high-quality processes, products, or services that meet customer needs. CTQs are measurable characteristics that ensure customer satisfaction. To identify them, an analysis of the Voice of Customer (VoC) is required. This analysis helps identify customer requirements that are not inherently measurable, which are then translated into CTQs. EA useful tool for making these requirements measurable and specific is the CTQ tree, which represents customer desires as a tree diagram, allowing for a more precise categorization.
Cause and Effect Matrix
The Cause and Effect Matrix, also known as the C&E Matrix, is a tool from Lean Six Sigma used to represent and prioritize multiple influencing factors on a defect (effect).
7 Quality Tools
The 7 quality tools are used for capturing, organizing, visualizing, and analyzing processes and their errors with the goal of identifying, assessing, and deriving corrective actions for problems. The 7 quality tools (Q7) include: (1) Error/Data Collection List – Helps in recognizing patterns and regularities. (2) Quality Control Chart – Used for visualizing the processes being examined. (3) Histogram – Represents data distributions. (4) Pareto Chart – Used for analyzing and prioritizing errors. (5) Brainstorming – A creative technique for generating ideas. (6) Ishikawa Diagram (Cause-and-Effect Diagram) – Used for problem analysis. (7) Correlation Diagram – Helps in identifying dependencies. The tools 1 through 3 are used for problem identification, while tools 4 through 7 are employed for problem analysis.
Voice of Business (VOB)
Voice of Business (VOB) is a tool used to translate verbal statements from all areas of your company about the process causing the issues into measurable core causes. These statements often relate to financial or strategic aspects such as revenue, costs, and delivery times. A VOB must always be present.
Voice of Process (VOP)
The Voice of Process (VOP) is a tool for translating verbal statements from the process into measurable core causes. All statements in the Voice of Process should be measurable in the Define phase of the project before moving into the Measure phase. VOP is a key element in the process model =().
Enterprise Alignment
This two-day workshop focuses on the leadership principles at the top level of the Shingo Model™—the purpose of the organization. Through practical on-site experiences at a host company, you will build on the knowledge and experiences from the DISCOVER EXCELLENCE workshop. Participants will dive deeper into the Shingo Model™ by focusing on the principles identified in the “Enterprise Alignment” dimension. To be successful, organizations must develop management systems that align behavior with principles. This alignment should be simple, comprehensive, actionable, and standardized. Creating value for the customer is ultimately achieved through the effective alignment of every value stream within an organization. The ENTERPRISE ALIGNMENT workshop continues the discussion on defining ideal behaviors and the systems that drive them.

Continuous Improvement
This two- or three-day workshop at a host company delves into the principles of continuous improvement. Building on the experiences from the DISCOVER EXCELLENCE workshop, you will learn five leadership principles and be empowered to clearly define value from your customers’ perspective. This workshop is particularly suitable for employees in the areas of Continuous Improvement (CI), Lean Management, and Six Sigma, as well as project managers and/or leaders. The group will continue discussions on ideal behaviors, purpose, and behavioral benchmarks. Participants will gain a deeper understanding of the Shingo Model™ by focusing on the “Continuous Improvement” dimension and its identified principles.
Content:
- Seek perfection
- Think scientifically
- Focus on process
- Ensure quality at the source
- See flow and pull as value
- Company assessment
Build Excellence
In this two-day final workshop, the insights and experiences from the previous five Shingo workshops are deepened. The BUILD EXCELLENCE workshop demonstrates the integrative application of systems that guide behavior toward the ideal—driven by the principles of the Shingo Model™. The workshop helps develop a structured approach to conducting cultural transformation, building on the foundation of established leadership principles. Workshop participants will learn how to build systems that promote behaviors that consistently deliver desired results. Experience how the Shingo Model™ supports the implementation of your business strategy. Elevate your organizational culture to the next level, aligned with your business objectives.
