These weeklong improvement events are popular in health and social care, but there are no textbooks available to support them. There are several books that describe the use of shorter Kaizen events in health care, but none that describe the process of delivering weeklong events. The events have a rhythm specific to the one-week format, and the book seeks to help people to make use of best practice and to avoid common problems. Based on the experiences of the authors, this book includes an introduction to Lean concepts linked to the relevant part of the process description; examples and templates of forms that can be used in workshops; and photographs of actual events.
