Lean Six Sigma Green Belt Define Phase Concepts Questions and Answers — Questions and Answers
Question 1: Which of the following is the PRIMARY output and foundational document of the Define Phase in a DMAIC project?
- A detailed process map
- A completed SIPOC diagram
- The Project Charter (Correct answer)
- A stakeholder analysis report
Correct answer: The Project Charter
The Project Charter is the most critical deliverable of the Define Phase. It is a formal document that officially authorizes the project, outlines its objectives, scope, team members, and alignment with business goals. While other documents like SIPOC diagrams and stakeholder analysis are created during this phase, the charter serves as the contract and reference guide for the entire project.
Question 2: A project team is in the initial stage of a Six Sigma project to reduce patient waiting times at a clinic. They are creating a high-level process map that identifies suppliers, inputs, the key process steps, outputs, and customers. Which tool are they using?
- Fishbone Diagram
- SIPOC Diagram (Correct answer)
- Control Chart
- Pareto Chart
Correct answer: SIPOC Diagram
A SIPOC (Suppliers, Inputs, Process, Outputs, Customers) diagram is a high-level process mapping tool used in the Define phase to provide a broad overview of a process. It helps the team understand the project's scope and the key elements involved before diving into detailed analysis.
Question 3: What is the main purpose of collecting the Voice of the Customer (VOC) during the Define Phase?
- To brainstorm potential solutions for the problem.
- To perform a detailed statistical analysis of process performance.
- To identify and prioritize the key drivers of customer satisfaction. (Correct answer)
- To select the final project team members and assign roles.
Correct answer: To identify and prioritize the key drivers of customer satisfaction.
The Voice of the Customer (VOC) is a systematic approach to capture customer needs, expectations, and feedback. In the Define phase, this information is crucial for understanding what is truly important to the customer, which helps in defining the problem, setting project goals, and identifying Critical to Quality (CTQ) characteristics.
Question 4: A well-written problem statement in the Define Phase should focus on:
- The proposed solution and its expected benefits.
- Assigning blame for the current process performance.
- The symptom of the problem, described in measurable terms. (Correct answer)
- A detailed list of all possible root causes.
Correct answer: The symptom of the problem, described in measurable terms.
A good problem statement should be specific, measurable, and focus on the observable symptoms of the problem (the 'what' and 'where'), not on potential causes or solutions. It quantifies the issue and its impact on business goals, providing a clear focus for the improvement project without jumping to conclusions.
Question 5: Which of the following activities is considered OUT of scope for the Define Phase?
- Developing a high-level project plan and timeline.
- Conducting detailed root cause analysis using the 5 Whys. (Correct answer)
- Identifying key stakeholders and their interests.
- Creating a project charter to get management approval.
Correct answer: Conducting detailed root cause analysis using the 5 Whys.
While preliminary root cause analysis might begin in the Define phase, detailed root cause analysis techniques like the 5 Whys and Fishbone Diagrams are core activities of the Analyze phase. The Define phase focuses on establishing the project's foundation, scope, and goals.
Question 6: A project team is working on improving the on-time delivery of a product. The Project Sponsor asks for the document that outlines the business case, problem statement, project scope, and key milestones. Which document should the Green Belt provide?
- RACI Matrix
- Communication Plan
- Gantt Chart
- Project Charter (Correct answer)
Correct answer: Project Charter
The Project Charter is the central document that contains all the elements requested by the Project Sponsor. It serves as the formal authorization and provides a high-level overview of the project, including the business case, problem statement, scope, goals, milestones, and team roles.
