The “DMAIC (Define, Measure, Analyze, Improve, Control Template Package)” delivers professionally produced, ready to use templates in a production or office environment.
What is it: The DMAIC (Define, Measure, Analyze, Improve, Control) is a six sigma process that is a structured approach for leading continual and breakthrough improvement initiatives. The DMAIC structure/model is based on the Plan, Do, Check, Act cycle developed by Dr. W. Edwards Deming. The DMAIC methodology differs from conventional problem solving in one significant way, that there is a requirement for proof of cause and effect before improvement action is taken. Proof is required because resources for improvement actions are limited in most organizations.
The steps in the DMAIC process:
Define phase: Understand what process is to be improved and set a goal
Measure phase: Measure the current state
Analyze phase:
Develop cause-and-effect theories of what may be causing the problem
Search for the real causes of the problem and scientifically prove the cause-and-effect linkage
Improve phase: Take action
Control phase:
Measure to verify improvement has taken place
Take actions to sustain the gains.
Why use it: DMAIC Problem-Solving (Define-Measure-Analyze-Improve-Control) is a step-by-step problem-solving methodology used by many companies for teams to address and solve problems by uncovering and eliminating the root cause of the problem.
Where to use it: DMAIC is a core part of the six sigma process mainly used in manufacturing environment .
When to use it: DMAIC methodology is a search for the real causes of problems, then applying the various tools and techniques used to answer these questions in difficult to solve problems.
How to use it: The DMAIC methodology generally follows the following guidelines:
DEFINE:
Prioritize and select project
Define project boundaries, measures, and project outcome
Charter team, define roles and responsibilities
Define customer and supplier requirements
MEASURE:
Assess current measurements, measurement capability
Develop measurement plan, correct measurement system
Gather data on the process, its inputs, and its outputs
Map current value stream
ANALYZE:
Use statistical and analytical tools to understand the process
Fix the obvious
Make additional measures as needed
Do detailed process mapping
Create future value stream map
IMPROVE:
Eliminate or reduce root causes of input/output process variables
Improve or re-design the process
Implement workplace organization (5S)
Improve material replenishment system (e.g., Kanban)
Implement Visual Controls
Pilot and verify changes, then implement
CONTROL:
Error proof the improved process
Study measures to confirm effectiveness, or make changes
