Six Sigma (DMAIC)
Reference model
DMAIC stands for Define, Measure, Analyze, Improve, and Control, which are the five phases of the methodology.
About this model
A data-driven quality strategy used to improve processes by eliminating defects and minimizing variability.
Originator not stated.
How to read it
- Follow the DMAIC phases in order to systematically improve processes.
- Each phase builds on the previous one, ensuring a thorough analysis and solution.
What this does
Provides a structured approach to improve processes by identifying and eliminating defects, ensuring quality and efficiency in operations.
When to use it
Use it when a process needs improvement, especially when defects are causing significant costs or customer dissatisfaction.
Not when: Do not use it when the process is already performing well or when there is no clear definition of the problem.
What happens next
Consider using a control plan to sustain improvements made through DMAIC.
