- 6 Sigma is a process of knowing and reducing variation so that consistency is achieved within prescribed limits. This is a proactive process of achieving and sustaining quality.
- 8D starts from a deviation / problem and systematically finds solutions in the short run, long run and find methods to keep that in control. This is a kind of reactive method but with the same objectives.
One tries to achieve quality by providing value and the other by eliminating defects.
