An alternative to the Six Sigma Green Belt Certification Program, Lean Six Sigma training combined with DFSS, may be a better career path for you.  Lean Six Sigma training covers much of the same information you would receive in the Green Belt Program with the addition of DFSS (Design for Six Sigma) and Lean processes.

DFSS (Design for Six Sigma) is a great quality improvement tool used when the process or product has not yet been developed. Instead of fixing problems within existing process, DFSS is designed to eliminate problems before they occur by creating a design based on the principles of Six Sigma.

While DFSS, or Design for Six Sigma, is technically considered a completely different process approach to business management and process or product improvement, it still relies on many of the same principles of traditional Six Sigma Training.

This article explains an overview of specific DFSS tools and resources.

When people talk about Six Sigma, they usually are referring to the DMAIC (define, measure, analyze, improve, control) methodology, which is used for optimizing an existing product or process, which may not be meeting customer needs or specifications. Design For Six Sigma, or DFSS, is quite different from DMAIC, as it is used for designing a completely new product or process that meets customer specifications. Compared to DMAIC, which is universally applicable on any business process, DFSS concepts and techniques do not have universal recognition.

The first thing that comes to the mind when you are referring to the practice of Six Sigma is the DMAIC methodology, which is used for improving an existing product that is not meeting a customer's specifications. It is universally recognized and defined as involving the phases of Define, Measure, Analyze, Improve and Control. The use of these phases may differ from one organization to another. Its need arises because of the heavy costs on resources being incurred by the processes.
