Should my company pursue Six Sigma, Lean, or ISO 9001?

It is not an either/or proposition—these programs are complementary, and your organization should be pursuing all three.

• ISO 9001 is a model for quality management systems. It provides a foundation for process management by helping to define the processes needed to obtain the planned results.
• Six Sigma is a model for designing, managing, and improving process results. It focuses on the effectiveness or accuracy of the process.
• Lean Enterprise is a model for designing, managing, and improving process flow. It focuses on the efficiency or speed of the process.
