The six sigma process.

Six Sigma Process

Six Sigma is a problem solving methodology. Its bases can be broken down into two parts. The equation y=f (x), and the acronym DMAIC, which stands for Define, Measure, Analyze, Improve, and Control.

All of Six Sigma designs begin with one equation. This equation is Y=f (x) + E, where Y is the outcome, the desired result. X, is the input. The factors, which are needed to construct the outcome. You may have several X values. The determining factor is f; this is the function (process), which the input is transformed into the outcome. E is the presence of ERROR. It is the uncertainty of depending on the Xs and the transformation function to reach the desired outcome. By reducing variation you can reduce deviation to an acceptable 3.4 parts per million.

Every Six Sigma project follows DMAIC, which can improve any process in any organization,
which improves its proficiency and success.

Define the context and objectives of the project.
Measure is to understand the process, validate the data accuracy, and determine
the process being improved.
Analyze the data and tools in order to understand the cause-and-effect in the system.
Improve by developing modifications, which will validate improvements in the system.
Lastly, Control, is the establishment of plans and procedures to ensure all improvements
are maintained.
