Lean Six Sigma is a globally proven methodology for the sustainable and demonstrable improvement of processes and organizations. It offers an approach with which organizations can achieve concrete results in a structured manner (Define, Measure, Analyze, Improve and Control or DMAIC) with continuous improvement.
The starting point is focus on what customers really consider important and to realize this in processes. No more and no less. With this approach, costs are reduced, customer satisfaction is increased and the lead time is shortened. The strength of this approach is that it uses existing knowledge and experience of people within the processes.
The Lean Six Sigma method improves both the process and the quality. Lean strives for more flow and generating value. Six Sigma strives for stable and effective processes. In combination they reinforce each other and are completely complementary.

Process improvement is a challenge. If the right people with the right Lean Six Sigma skills are involved, significant and lasting change can be achieved. The use of the term ‘belts’, bands in Dutch, comes from Karate. This indicates the different skill levels. Here are the main roles in Lean Six Sigma:
Lean Six Sigma was developed from two methodologies: Lean and Six Sigma.
Lean’s fundamentals can be traced back to Toyota Production Systems (TPS). The Japanese Taiichi Ohno is the founder and based on developments from innovations by, for example, Henry Ford and methodologies such as Business Process Redesign.

Six Sigma was developed in the same time as Lean and is more data-driven. The method was developed by Motorola and widely and very successfully applied by General Electric.
The structured project approach Define, Measure, Analyze, Improve and Control (DMAIC) ensures that the root cause of a problem is first found before a solution is implemented. By applying the DMAIC Model you use the capacities of your employees within the organizational structure in an efficient and intelligent way to create as much value for the customer as possible. A variant of this model is the DMADV or DFSS (Design For Six Sigma): Define, Measure, Analyze, Design and Verify. By determining and measuring the company’s important indicators, it becomes clear where improvements need to be made. Management receives targets and tools for this through Six Sigma and this creates a structured improvement model. As with Lean, this is based on the added value for the customer.

The two methods are very complementary because they both start from the wishes of the customer, the process and improve it together with employees. Lean Six Sigma tackles business problems at the core and ensures continuous improvement.
