Free Lean Six Sigma Green Belt DMAIC: Define Phase Concepts Questions and Answers

Question 1

A Six Sigma project team is in the initial stage of defining a project to reduce customer complaint resolution time. Which of the following is the MOST crucial initial step for the team to take in the Define phase?

Accepted Answer

Create a Project Charter to formalize the project's purpose, scope, and goals.

Answer

The Project Charter is a foundational document in the Define phase. It formally authorizes the project and provides a clear outline of its purpose, scope, goals, team members, and stakeholders. Creating the charter ensures everyone is aligned before any other significant activities, like detailed process mapping or data collection (which are also part of DMAIC but typically follow the charter's creation), are undertaken. Brainstorming solutions is premature and belongs in the Improve phase.

Question 2

A project team is developing a high-level view of a process to understand its boundaries, stakeholders, and the flow of materials and information. They are identifying the suppliers, inputs, key process steps, outputs, and customers. Which tool are they using?

Accepted Answer

SIPOC Diagram

Answer

A SIPOC diagram stands for Suppliers, Inputs, Process, Outputs, and Customers. It is a high-level process map used in the Define phase to provide a broad overview of a project, identify key stakeholders, and establish the project's scope before diving into a more detailed process map.

Question 3

Which of the following is the primary purpose of collecting the Voice of the Customer (VOC) during the Define phase of a DMAIC project?

Accepted Answer

To translate customer needs and expectations into specific, measurable requirements.

Answer

The Voice of the Customer (VOC) is a systematic approach to capture customer needs, wants, and expectations. In the Define phase, this feedback is critical for translating often vague customer comments into specific, measurable Critical to Quality (CTQ) characteristics that will guide the project's objectives.

Question 4

A hospital's project team has been tasked with improving the patient discharge process. They gathered feedback from former patients (the Voice of the Customer) who stated they want a 'fast and easy' discharge. How should the team translate this VOC into a more useful project metric?

Accepted Answer

By identifying Critical to Quality (CTQ) characteristics, such as 'Discharge process completed within 30 minutes of doctor's order'.

Answer

The process of translating broad customer statements (VOC) into specific, measurable requirements is key to the Define phase. Critical to Quality (CTQ) characteristics break down general needs like 'fast and easy' into actionable metrics, such as a target time for completion. This provides a clear, measurable goal for the project.

Question 5

Which of the following elements is LEAST likely to be found in a well-defined Project Charter?

Accepted Answer

A detailed root cause analysis of the problem.

Answer

A Project Charter is created in the Define phase to outline the problem, goals, and scope. A detailed root cause analysis is the primary objective of the Analyze phase and would not be included in the initial charter, as the causes of the problem are not yet known.
