Many excellent books have been written on Lean and Six Sigma. However, just reading the books will not give you the skills to use the techniques successfully. You can develop these skills by making exercises. This book contains 60 exercises and rationals and is therefore a valuable addition to any theoretical Lean and Six Sigma course. Even experienced Lean Six Sigma specialists can use this exercise book to improve their practical skills. Finally, this book is useful for trainers and teachers who provide training within their own organization or in education.
The structure of this exercise book is based on the "Continuous Improvement Maturity Model" (CIMM). CIMM is an open standard which is maintained by the Lean Six Sigma Academy (LSSA). This framework describes the process of continuous improvement from the initial phase to the delivery of products and services at the level of ‘World Class’. The CIMM framework connects the different methods and encompasses the most commonly applied techniques in the field of problem solving, continuous improvement and new product development.
This exercise book is a supplement to the textbook ‘Climbing the Mountain’ by H.C. Theisens. Together, these books form the basis for developing yourself in the beautiful field of problem solving and continuous improvement. This book contains examples from multiple sectors. However, all exercises can be made without having prior knowledge of a certain sector.
To make the exercises in this book, sometimes Excel is used. The data files required for the exercises can be downloaded from the website of the LSSA: www.lssa.eu.
If you only want to practice with Lean, it is sufficient to make the exercises in chapters 1 to 6 only. Six Sigma topics are covered in Chapter 7. The exercises that only need to be completed by Orange Belts are indicated by ‘(OB)’.
