Sigma Six: The Methodology Explained

Sigma Six, or Six Sigma, is a lot more than certification program. This is process management methodology, the way of thinking and keeping processes cost-efficient and timely.

Looking at the bigger picture, one could say that Six Sigma is a management philosophy, strategy and collection of approaches united by the goal of reducing defects in products and services. Six Sigma is all about improving process output.

Six Sigma employs two different approaches: DMAIC and DMADV:
