In this book, the author introduces the academic world to the concept of Lean Thinking. Although Lean is popular in industry and commerce, having brought tremendous improvements in product and service quality as well as reducing costs and process times, it has barely made inroads into schools. The author takes readers through a journey of why it is important to consider Lean as an alternative to resolving the current issues in classrooms. A case study that was done over a several years within a school environment to test the principles and tools is detailed, including the results and the inferences made out of them. A checklist to asses a school's preparedness for a Lean roll-out as well as a typical implementation plan and models is included.
