This book consistently emphasizes practical relevance, demonstrating how four successful and established companies become and remain competitive through Lean Management: Lufthansa Technik, Philips Medical Systems, Raytheon Anschütz, and Single Temperiertechnik. Managers, trainers, consultants, and employees responsible for a Lean initiative will find themselves reflected in these examples and gain diverse inspiration. The 20 most important Lean tools are presented, and the responsible parties speak openly and honestly about the challenges of Lean deployment. Finally, experts from Daimler, Lumics, Miele, and Staufen evaluate the approaches of the respective companies and explain in interviews what they might have done differently. The reader reflects and gains a new perspective through the insights of the experts.
