DMAIC Processes Exam Questions and Correct Answers Latest 2025
What is a Green Belts role? - Answers are the project leaders, they formulate and assist the Six Sigma
team and see it through commencement of the project to its completion. Work part time on the chosen
projects
What is DMAIC? - Answers Data driven processes.
Defining the aims
Measuring the current procedure
Analyzing the current procedure to remove loopholes between the current procedure and the aimed
results
Improving on the current procedure and finding innovative techniques
Controlling improved performances
What happens in the Define phase? - Answers In this stage goals of any project and its customer
deliverables are defined.
it identifies the inherent problems in the system and develops a problem statement.
the goal of implementing Six Sigma and its benefit to that particular organization.
The strategic organizational support for that particular project is evaluated.
The project plan and its milestones are developed. This also covers process mapping and flowcharting,
project charter development, problem solving tools, and the 7M tools.
Measure Phase - Answers measures the existing system for defects, opportunities, units and metrics. It
establishes statistical process control techniques and data analysis methods. It also develops a data
collection plan to measure the defects; and it helps in monitoring the progress of the project towards
the defined goals. This phase covers the principles of measurement, studies of continuous and discrete
data, graphical analysis techniques, basic capability indices, and so forth.
Analysis Phase - Answers working on the data generated from the various methods provided in the
measure phase, and analyzing the defects by trying to reach the root cause. This phase uses various data
analysis techniques to analyze the generated data. Here the system tries to pinpoint the deviation from
the identified goals and identify the sources of these variations.
The various statistical techniques used are Statistical Process Control Techniques, Process Capability
Analysis, Statistical analysis of cause and effect relationship using regression and correlation, chi-square
tables, specialized control charts and so forth.
, Improve Phase - Answers the analysis is used to improve the existing system by removing the identified
flaws. It is used to generate new, innovative, and cost effective solutions and ideas to the problem and
implement them. The results for the defined problem may be statistically evaluated to solve the flaw.
The process is then optimized based on the analysis using various Design of Experiments methods like
ANOVA, and process optimization.
Control Phase - Answers In this phase, the improvements have to be controlled, to keep the
standardized process on its new course. A strategy has to be developed to prevent the process from
reverting to the previous way. This requires development, documentation, and implementation of the
new plan. After this, trial runs to establish process capability have to be conducted, which help in the
transition of the planned process to production. Finally, the process with the instituted control
mechanisms needs to be continually measured.
This phase covers process control planning, using SPC (Statistical Process Control) for operational control
and pre-control.
Define Phase Objectives - Answers Develop a team/project charter
Identify the customers for the project, their needs and requirements
Identify which critical to quality factors are considered
The execution of any project consists of three important elements. They are: - Answers Project Charter
Identification of the customer
Making a high level process map
What does the Project Charter contain? - Answers The Business Case
The Problem it is Addressing
The Project Scope
Project Leader (Black Belt/Green Belt)
The Mentor/Master Black Belt
Project Commencement Date
Projected Project Conclusion Date
Who developed the kano model? - Answers A Japanese researcher, Noritaki Kano, developed the Kano
model of customer satisfaction.
