KAIZEN™ has been evolving since its founding

  • 1950-1980: Companywide KAIZEN™ efforts started in Japan with the Quality Movement
  • 1980-2010: Toyota perfected the Toyota Production System (TPS) and the term Lean was born
  • 2010-2020: The TPS was very powerful but it demanded strong leadership, thus arose the concept of Lean Transformation
  • +2020: KAIZEN™ did not stop and companies like Toyota and Danaher expanded Lean to all growth areas
  • kaizen-lean-evolution-industrialisation-digital


The fourth generation of KAIZEN™ aims to deliver and drive profitable growth by expanding operational excellence to business excellence. The Enterprise Business System was born out of KAIZEN™ 4.0.
