This book shows the basics, methods and principles of lean process design in production as well as in other areas such as development, engineering and administration. In addition, it serves as a reference work for practical use. Questions have been developed for each topic area for process analysis. These can be used for self-reflection and benchmarking. Numerous examples, a continuous fictitious industry case as well as learning objectives and exercises with solutions for each chapter supplement the explanations and enable optimal exam preparation. This book is a translation of the original German 2^nd edition Lean Management by Frank Bertagnolli, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2020. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that thebook will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
