Free Lean Six Sigma Green Belt DMAIC: Define Phase Concepts Questions and Answers — 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?
- Develop a detailed process map of the current complaint resolution workflow.
- Create a Project Charter to formalize the project's purpose, scope, and goals. (Correct answer)
- Brainstorm potential solutions for reducing resolution time.
- Collect baseline data on the current average resolution time.
Correct answer: Create a Project Charter to formalize the project's purpose, scope, and goals.
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?
- Fishbone Diagram
- Pareto Chart
- SIPOC Diagram (Correct answer)
- Control Chart
Correct answer: SIPOC Diagram
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?
- To select the members of the Six Sigma project team.
- To create a budget for the implementation of the solution.
- To translate customer needs and expectations into specific, measurable requirements. (Correct answer)
- To immediately implement changes based on customer feedback.
Correct answer: To translate customer needs and expectations into specific, measurable requirements.
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?
- By surveying doctors on what they consider a fast discharge.
- By identifying Critical to Quality (CTQ) characteristics, such as 'Discharge process completed within 30 minutes of doctor's order'. (Correct answer)
- By implementing a new software system immediately to automate the process.
- By adding more staff to the discharge team to make it seem faster.
Correct answer: By identifying Critical to Quality (CTQ) characteristics, such as 'Discharge process completed within 30 minutes of doctor's order'.
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?
- A detailed root cause analysis of the problem. (Correct answer)
- A clear problem statement with quantifiable metrics.
- The project scope, including what is in and out of scope.
- The business case explaining why the project is important.
Correct answer: A detailed root cause analysis of the problem.
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.
Question 6: The primary output of the Define phase in a DMAIC project is a(n):
- Completed control plan to sustain the gains.
- List of validated root causes for the identified problem.
- Implemented and verified solution to the problem.
- Approved Project Charter and a clear understanding of the project's scope and goals. (Correct answer)
Correct answer: Approved Project Charter and a clear understanding of the project's scope and goals.
The main goal of the Define phase is to establish a solid foundation for the project. This is accomplished by creating a Project Charter that documents the problem, goals, scope, and business case, and ensuring the team and stakeholders have a shared understanding of these elements before proceeding. The other options are outputs of later DMAIC phases: root causes (Analyze), implemented solution (Improve), and control plan (Control).
