What is Lean Six Sigma?

Lean Six Sigma is a globally proven and applied methodology that provides a demonstrable and sustainable improvement of the operating result. Here the focus is on what the customer really thinks is important. This approach leads to the simultaneous reduction of costs, increasing customer satisfaction and shortening the lead time. This involves investing in your own people and using their knowledge and expertise.

Lean Six Sigma offers a framework with which an organization can continuously improve in a structured way. Implementing Lean Six Sigma gives an organization a targeted approach to turn the strategy into concrete results and be more successful than its competitors.

Lean Six Sigma projects ensure a sustainable improvement of the operating result. Business problems are solved better and permanently. The return on investment of a Lean Six Sigma process varies, but is always a multiple of the investment. A Return on Investment of four for a Green Belt training, based on the total investment in time and money, is more normal than exceptional. Successful Lean Six Sigma implementation programs achieve ROIs of 40 to 80.

Course objectives

How does Lean Six Sigma work?
The focus of Lean Six Sigma is on increasing customer satisfaction and generating (financial) results for the organization. By focusing on what is really important for the customer and reducing errors in implementation, the number of process steps is reduced (Lean) and the outcome of the processes is made predictable (Six Sigma).

The strength of Lean Six Sigma lies in four areas:

  1. Quality improvement
    Lean Six Sigma sets a strong foundation for quality improvement. By training their own employees, they are able to improve their processes themselves. This is done in the form of a project using the DMAIC methodology. Management and management are also actively involved in this process.
    Improvement of the lead time
  2. Lean Six Sigma exposes the so-called "hidden factory". Often there are many processes and procedures in organizations to solve problems, but these costs take a lot of time and often lead to frustration. Organizations often do not have the time to investigate where exactly it goes wrong; where the waste is. DMAIC exposes the hidden factory and breaks it down.
  3. Organizations learn to improve themselves
    Focus on the added value for the customer is central. Meeting the customer's wishes not only increases customer satisfaction, but also helps organizations to look at their services, products and processes over and over again and continuously improve them.
  4. Better operating result
    Improving the processes with Lean Six Sigma contributes directly to the operating result. According to Lean Six Sigma, quality is not an end in itself, but a means to achieve the real goal, namely to improve the operating result by generating customer value.

Why is Lean Six Sigma so popular?

Lean Six Sigma is so popular because it has helped many thousands of companies around the world to become successful and achieve the desired results. It is the most effective method to achieve lower operating costs, higher profits and greater customer satisfaction.
Lean Six Sigma started in the industry, but has successfully manifested itself in almost every type of organization including the Service Industry over the last fifteen years.
