140 Exercises and Rationals
Paperback Engels 2023 1e druk 9789401809825Samenvatting
It is important for businesses and organizations to continuously focus on customer satisfaction by supplying products or services with outstanding quality, cost efficiently and delivered within the agreed lead time. Improving quality and efficiency is the domain of Process Improvement.
Realizing these objectives is effectively achieved by applying Lean Six Sigma: a combination of Lean Manufacturing and Six Sigma approaches. Within Lean Six Sigma, individuals can be trained at various Belt levels. These levels are called Yellow Belt, Orange Belt, Green Belt and Black Belt.
There are many excellent books about the Lean Six Sigma theory. However you cannot learn how to apply Lean Six Sigma by only reading books. You need to learn by doing and practicing. This exercise book is a valuable addition in Lean Six Sigma training events. Even experienced Lean Six Sigma Green and Black Belts can use this exercise book to improve their Lean Six Sigma skills.
