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

The simple answer is that six sigma is a very formal, systematic approach to solving problems. It follows a somewhat generic pattern. However, it takes a more holistic approach for the entire organization. Rather than sub-optimizing the solution to a specific problem or concern, it forces the experimenter to see the whole solution and its effects. The problem-solving approach that six sigma takes is basically:

• Defining the problem. Listing and prioritizing problems, defining the project and the team.

• Diagnosing the problem. Analyzing the symptoms, formulating theories of causes, testing these theories, and identifying root causes.

• Remedying the problem. Considering alternative solutions, designing solutions and controls, addressing resistance to implementation, implementing solutions and controls.

• Holding the gains. Checking performance and monitoring the control system.
