Lean Six Sigma Green Belt Define Phase Concepts Questions and Answers

Question 1

Which of the following is the PRIMARY output and foundational document of the Define Phase in a DMAIC project?

Accepted Answer

The Project Charter

Answer

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?

Accepted Answer

SIPOC Diagram

Answer

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?

Accepted Answer

To identify and prioritize the key drivers of customer satisfaction.

Answer

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:

Accepted Answer

The symptom of the problem, described in measurable terms.

Answer

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?

Accepted Answer

Conducting detailed root cause analysis using the 5 Whys.

Answer

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.
