The book ‘Lean Administration step by step’ is aimed at specialists and executives who want to apply lean in the indirect areas of the company or in service. It is intended as a practical manual and describes the implementation process step by step. Particular value is placed on the organization of the change that goes hand in hand with lean implementation. Normally, lean projects do not fail because the technology or methodology does not fit, but because components of the change process are not or not sufficiently taken into account. The structure of the book follows a systematic approach that has proven itself many times in practice. Checklists and forms supplement the presentation and can also be downloaded here bit by bit. The detailed report of a Lean user shows what really works in practice.
