Six Sigma Fundamentals: A Complete Introduction to the System, Methods, and Tools

The DCOV model is the official model methodology design for six sigma. It stands for define, characterize, optimize and verify. Fundamentally, the model helps in the following:

• Defining what the customer needs, wants and expects.

• Defining the specifications for those needs, wants and expectations.

• Optimizing the specifications for the specific needs, wants and expectations.

• Verifying that the needs, wants and expectations are indeed what the customer wanted.
