Six Sigma Methodology

Six Sigma Orgin

Dating back to the late 18th century when mathematicians first introduced the 'normal curve,' Six Sigma has been an effective method of fine-tuning the measurement of process improvement. 'Sigma,' meaning a standard deviation from the goal of the process, is a way of measuring defects in mathematical formulas, and more recently, business processes. This sounds complicated - it doesn't have to be!!

In the 1920s, business leaders found that three sigma from the mean is the point where a process requires correction. As businesses grew in scale, the toleration for standard deviation grew to six sigma. In the 1980s, Motorola implemented the Six Sigma methodology which in turn saved them $16 billion dollars and brought the idea to light for tens of thousands of companies.

Achieving stable and predictable process results is the focus of Six Sigma methodology. Six Sigma aims at analyzing definable, measurable, improvable, and controllable processes, similar to The DMAIC Way that has stemmed from this idea. The emphasis on leadership and supporting roles makes Six Sigma a powerful way to delegate tasks to team members trained in their roles.

Six Sigma's belt system trains team members on the various aspects of a project, like data collection and analysis, reviewing project processes, and managing project roles. A strong understanding of Six Sigma philosophies and principles helps businesses handle projects and perform at their best.
