Did you know that employees in German companies consider almost 30% of their working time to be waste? Lean Administration helps to identify this waste. Volume 1 of "Lean Administration Step by Step" demonstrated how waste can be recognized and analyzed. The following Volume 2, "The Implementation," describes how Lean Administration is successfully and sustainably implemented after the analysis phase, creating the conditions for a cultural shift towards a "Lean Company." One of the main focuses is on designing the change processes associated with each Lean implementation. Methods and tools of change management that have proven effective in practice are presented clearly. The theoretical discussions are complemented by practical case studies and useful tips.
