The main focus of SIX sigma is on reducing defects and
variations in the processes.DMAIC and DMADV are the models used in most SIX
sigma initiatives. DMADV is model for designing process while DMAIC is for
improving the process.
DMADV model has the below five steps:-
- Define: - Determine the project goals and the
requirements of customers (external and internal).
- Measure: - Assess customer needs and specifications.
- Analyze: - Examine process options to meet customer
requirements.
- Design: - Develop the process to meet the customer
requirements.
- Verify: - Check the design to ensure that it’s meeting
customer requirements
DMAIC model has the below five steps:-
- Define the projects, the goals, and the deliverables
to customers (internal and external). Describe and quantify both the defect
and the expected improvement.
- Measure the current performance of the process.
Validate data to make sure it is credible and set the baselines.
- Analyze and determine the root cause(s) of the
defects. Narrow the causal factors to the vital few.
- Improve the process to eliminate defects. Optimize the
vital few and their interrelationships.
- Control the performance of the process. Lock down the
gains.
