Lean Six Sigma is a management approach to business performance improvement that has blended the two individual specialisms of Lean and Six Sigma. Competition in the highly lucrative financial and commercial sectors as a project manager or management consultant is fierce. Companies have their choice of candidates and currently one of the criteria used for sorting the wheat from the chaff is by selecting certified candidates. Certification in Lean management or a Six Sigma certification are both highly regarded by the industry so a Lean Six Sigma certification, therefore, goes a long way to getting your credentials to the top of the pile. Combine the two levels of Six Sigma certification and sign up for the Six Sigma Green and Black Belt Combo course today. The course offers over sixty lectures that will teach you how to implement Six Sigma management principles to help organizations decrease their operating costs. It will show you how to implement the concepts of Six Sigma and guide you to inspire greater levels of customer satisfaction and loyalty.

 

There are no official sources of certification for Six Sigma or for the Lean principles of management, but there are institutions that offer these certifications. Due to the fact that there is no central body for either of these certifications, the levels and subjects taught within these certifications are not standardized. Different certification organizations also have different reputations within the market so it’s important to do some homework within the industry you are interested in to find out which institutions and certifications carry the most weight.

There are however some similarities between the various organizations offering certification. Six Sigma certification normally requires a certification for the four levels or belts of Six Sigma and Lean certification normally includes certification for the three levels of Lean certification.

 

The application of Lean Six Sigma allows quality and efficiency improvements to be effectively realized. The focus of Lean is about speed, efficiency, and taking waste out of a process. Six Sigma focuses on effectiveness and removal of errors. Lean Six Sigma combines Lean Manufacturing (originally developed by Toyota) and Six Sigma (originally developed by Motorola). Both management strategies are among the most used worldwide and have experienced proven success in a wide variety of industries. When combined and implemented properly, it can be a powerful management tool that can greatly improve an organization’s performance, by providing a structured approach to resolving problems. There are four levels of Lean Six Sigma qualifications: Yellow Belt, Orange Belt, Green Belt, and Black Belt. The four levels of Lean Six Sigma qualifications are based on EU funded research by the Lean Six Sigma Academy (LSSA) to determine a common standard for Lean Six Sigma qualifications and to specify which of the overall Lean Six Sigma tools and techniques are expected to be included within the competences of each Belt level. A Lean Green Belt certification is also available: https://apmg-international.com/product/lean-green-belt Individuals can enter the certification at any Belt level, depending on previous knowledge and experience. Therefore, it is not necessary to achieve a lower Belt certification before moving on to a higher level. The Lean Six Sigma certifications (for all belts) are available in English and Dutch.

 

Six Sigma Certification Levels

 

The Six Sigma training course is divided into four levels or “belts.” These levels are consecutive, with higher belts or levels requiring more understanding and skill than the lower belts. Six Sigma belts increase in order of yellow belt certification, green belt certification, black belt certification and champion certification. Six Sigma training includes training on the principles of Six Sigma developed by Jack Welch while at Motorola. Six Sigma training includes training students on the application and implementation of strategies based on the DMAIC principles of define, measure, analyze, improve and check. Students are also taught the DMADV approach to management which is an acronym for Define, measure, analyze, design, and verify. Finally, students are taught various quality management tools and techniques including the “five why’s” of management, the CTQ tree, statistical tools, cost-benefit analysis, and business process mapping.
