n every interview , the interviewer basically ask about six sigma and importance of it, You can search Google and understand the purpose of six sigma , definition of six sigma but you stuck while talking about DMAIC, primarily when interviewer ask in which phase what tool to be used. Here We go to simplify your all questions.

1. DMAIC
Understand the Process of DMAIC .
The Articles defined for help and to educate our
Six Sigma Certified Associates to run business and
process in dynamic way.

8 – Discipline Methodology
(by ford)
DMAIC Methodology DFSS (DMADV)
 Used for –
 Problem solving
 RCA
 Permanent Corrective
Action
 Systemic Action
Used For
 Problem Solving
&
 Process Improvement
Used For
 Design new product or
process
 Re-design existing
product or process
Leads to
 Continual Improvement
Leads to
 Continual Improvement
 Breakthrough
Improvement
Leads to
 Design / Redesign or P n
P with fewer defects
means 4.5 sigma at
least.
Before Creating any project you must know what Method can fit for
your project, Basically there are 3 tool which we used while designing
any project.
1. TQM – Total quality management – 8D Method
2. DMAIC – Define Measure Analyze Improve & Control Method
3. DMADV – Define Measure Analyze Design & Verify Method

3. *
Define: - Based on your CTQ /CTP
Define Phase Steps / Tools
 Define customer and their requirements
(CTQs)
 Develop Project Charter
 Develop High Level Process Map
 Action plan for process standardization
 V.O.C Gathering and CTQ definitions
 Problem Statement
- Goal Statement
- Business Need Addressed
- Scope / Boundaries of the project
- Constraints
- Resources Needed
- Assumption
- Team Guidelines
- Team Composition
- Preliminary Project Milestones
 SIRPOC (SIPOC)
 Interim Containment Action
Define Tollgate Review ( Check List )
In Define Phase we Define Project Charter which includes Business Goal ,
Problem Statement , High Level Process Map , what Action we are going
to place and who all would be team member during this project
execution.

4. Measure: - Gather data to establish the current / baseline status, what is the
actually going on at the work place with the process as it works today quantify
the problem.
Measure Phase Steps / Tools
 Define Defect, Opportunity , Unit &
Metrics
 Identify the CTPs
 Develop the data collection plan &
format
 Validate the Measurement system.
 Collect the data
 Begin Developing Y = f(x) Relationship
 Calculate process capability and sigma
baseline
 Based on CTQs and process knowledge ,
Benchmarking
 Using Pareto , Correlation analysis, CT
matrix
 Questionnaires, Sampling plans
 Measurement System Analysis / Gage R &
R
 Check Sheet , Data Sets
 Correlation Analysis , Regression analysis ,
Design of Experiments
 CP , CPK , DPMO , / Sigma Level
Calculation
Measure : - Measure your Problematic Area

5. Analyze and determine the root cause of the defects. Interpret the data to
establish cause effect relationship.
Analyze Phase Steps / Tools
 Identify Value / Non-value added
process steps.
 Identify source of variation.
 Determine Root cause
 Determine vital few X’s , Y = f(X)
 Prepare Action plan to explore various
solution for the causes.
 Process Map Review and vale Analysis.
 Histogram, Control Chart Box, Whisker
Plot.
 Cause and effect fishbone diagram , Ask
Why 5 Times , Pareto
 Correlation Analysis, Regression Analysis,
Hypothesis, Testing, Design of
experiments.
 Brainstorming, SWOT analysis.
Analyze : What went wrong and how it will correct.

6. Improve : - Develop solution targeted at the confirmed causes. Design work Flow
Improve Phase Steps / Tools
 Develop Potential ideas & Solutions
 Assess failure modes of potential
solution
 Reduce risks associated with potential
solution.
 Plan & Execute Solution on pilot basis.
 Fine tune the Potential Solutions.
 Check performance levels after
improvement.
 Brainstorming, DOE.
 FMEA
 Mistake proofing
 Verification
 Validation
 CP, CPK, DPMO , Sigma Level
Improve : - during this phase FMEA, Brainstorming play vital role to get the
work flow designed , What & How to perform action.

7. Control : - Develop consequence management to control , Conduct FMEA
Control Phase Steps / Tools
 Authenticated calculation of saving
achieved.
 Develop & Implement the document
plan.
 Develop & Implement the training Plan.
 Develop & Implement the Control Plan
 Plan the Audit schedules & audit
requirements
 Transfer of project to process owner.
 Determining improvement in process
capability & Process sigma.
 Standardized work (SOPs, WIS , etc)
 Competency Matrix
 Control charts.
 PDCACP , CPK, DPMO , Sigma Level
Control : - Applying consequence management to control the improvement ,
Design SOPs to sustain the achievements, develop & Implement training plan to
improve more.
