Who invented six sigma

Worldwide, many companies use this concept within and outside Six sigma framework. He was the one who first used Control Charts for Process control. Now, nobody can imagine Six Sigma implementation without Control charts. Coming to the official introduction of Six Sigma as a concept and methodology, we should know about engineers like Bill Smith, Michael Harry who did enormous research in developing Six Sigma as a concept and tool. One should also know about leaders like Bob Galvin, Jack Welch and Larry Bossidy for understanding the capabilities of this concept to its depth and providing enormous support and emphasis on utilizing Six Sigma to its full benefit.

Sigma is an actual term used in statistics that refers to the frequency of deviation from the standard. Six Sigma means that an error, or a variation from the standard, will occur only 3. Six Sigma as a metric formed the foundation upon which the Six Sigma quality improvement process is based.

While originally applied only to production environments, the concept of Six Sigma has since been applied to almost every form of business. As Six Sigma, and quality improvement itself, have become more popular in the business community, there has been less emphasis on the actual DPMO and more emphasis on how the process is improved. Although Six Sigma shows great strength as a metric and as a methodology, Motorola felt that an actual management system would best illustrate the strength of the Six Sigma concept.

To quote Motorola,. For greatest impact, Motorola ensures that process metrics and structured methodology are applied to improvement opportunities that are directly linked to the organizational strategy.

When practiced as a management system, Six Sigma is a high-performance system for executing business strategy. Six Sigma is a top-down solution to help organizations:. The Six Sigma Management System drives clarity around the business strategy and the metrics that most reflect success with that strategy.

It provides the framework to prioritize resources for projects that will improve the metrics, and it leverages leaders who will manage the efforts for rapid, sustainable, and improved business results. Has sold this ridiculous idea to make a company believe that this certification will guarantee the qualification of the employee knowing how to deploy Lean.

Only practicing concepts, fundamentals, and principles of Lean as the Japanese intended, guarantees correct Lean application. Test, multiple choice questions, and memorization of Lean tools will prove anything. The Japanese does. The Six Sigma communty has coined the phrase Lean Six Sigma to hold on to their cash flow over the free cost of Lean as the Japanese will freely teach anyone.

Any tool or technique in Six Sigma can get analyzed to show how it improves a process. But one of the most used methods in Six Sigma is DMAIC, a step-by-step process that allows users to make improvements to a current process by using data and objective problem solving. Define — A project team uses a team charter to select team members, choose the process being improved and define the project objectives.

Measure — The team collects data on the process. One of the areas of focus is finding variance in a process. One of the main objectives of Six Sigma is to target and eliminate variance. Analyze — A data-driven approach is taken to finding potential solutions to whatever problems have been identified. This is an area where a variety of Six Sigma tools can come into play, including regression analysis and variance analysis.
