DMAIC MCQs : This section focuses on the "DMAIC" in Statistical Quality Control. These Multiple Choice Questions (MCQs) should be practiced to improve the Statistical Quality Control skills required for various interviews (campus interview, walk-in interview, company interview), placement, entrance exam and other competitive examinations.
DMAIC an acronym for?
A. Data, Measure, Analyze, Improve and Control
B. Define, Mean, Analyze, Improve and Control
C. Define, Measure, Analyze, Insert and Control
D. Define, Measure, Analyze, Improve and Control
Explanation: DMAIC an acronym for Define, Measure, Analyze, Improve and Control.
The purpose of this step is to clearly pronounce the business problem, goal, potential resources, project scope and high-level project timeline.
Explanation: Define : The purpose of this step is to clearly pronounce the business problem, goal, potential resources, project scope and high-level project timeline.
The purpose of this step is to measure the specification of problem/goal.
Explanation: Measure : The purpose of this step is to measure the specification of problem/goal. This is a data collection step, the purpose of which is to establish process performance baselines.
What DMAIC process does is, to _______
A. Manufacture any product
B. Define specification limits for a product
C. Define quality system standards
D. Solve root cause of quality and process problems
Explanation: DMAIC is a problem solving tool. Hence, its main objective is to find root causes of problems in a process, which create variability. It attempts to remove those root origins.
Analyse step is to identify, validate and select root cause for elimination.
C. Can be true or false
D. Can not say
Explanation: True, Analyse step is to identify, validate and select root cause for elimination.
Input is defined as _____
A. Changes made to controllable variables
B. Development of in the process
C. Material provided to a process
D. Desired product specification
Explanation: The input to a process is defined as the material and the information provided to a process, before it starts producing any product. This is an important factor to the quality of the product.
DMAIC is often associated with ______
A. Six-sigma activities
B. Kaizen board
D. Acceptance sampling
Explanation: DMAIC is often associated with six-sigma activities. The main objective of this is to give the maximum output with good quality. Almost all six-sigma implementation use DMAIC PSP for project management and completion.
Which of these is not necessary in a tollgate report after measure step of DMAIC?
A. A list of identified KPIV’s and KPOV’s
B. SIPOC diagram
C. Measurement system capability
D. Assumptions made during the data collection
Explanation: In a tollgate review, all the important things used in measure step like KPIV’s and KPOV’s, capability of measurement system, and the assumptions made during the data collection etc are listed. SIPOC is the part of define step.
The Cause and Defect Diagram is a part of _____ step of DMAIC process
Explanation: The cause and defect diagram is an diagram which shows defects in a product, and the corresponding cause for it. This is counted in the Measure step of DMAIC.
Control is the final stage within the DMAIC improvement method.
C. Can be yes or no
D. Can not say
Explanation: Yes, Control is the final stage within the DMAIC improvement method.
