CLSSYB-001 practice question 10 of 25

The DMAIC approach to problem solving stands for Define, __________, Analyze, Improve and Control.

Full set: 120 questions
Answer options
A: Manage
B: Measure Correct answer
C: Memorize
D: Manipulate
Correct Answer:
B. Measure
Explanation

DMAIC is the foundational, data-driven problem-solving methodology used in Six Sigma projects. The acronym represents the five sequential phases of the process: Define, Measure, Analyze, Improve, and Control. The 'Measure' phase is the second step, where the project team establishes a baseline for the process performance by collecting relevant data. This quantitative understanding of the current state ("As-Is") is crucial for identifying the root causes of problems in the subsequent 'Analyze' phase and later verifying the effectiveness of implemented solutions.

Why Incorrect

A. Manage: While project management is integral to executing a DMAIC project, "Manage" is not one of the five distinct phases of the methodology itself.
C. Memorize: Memorization is a cognitive learning activity and is not a phase in this structured, analytical process improvement framework.
D. Manipulate: This term is contrary to the ethical and objective principles of Six Sigma, which relies on accurate data and statistical analysis, not manipulation.
