Changeovers in 3 minutes or less! That is the result of the process described in this book. Picking up where Dr. Shingo's Single Minute Exchange of Die left off, it streamlines the process even further to reduce changeover time and cut staffing requirements in half simultaneously!
The book describes how to achieve quick changeover in virtually any type of production environment with: the book includes—
-
A succinct eight-step process for setup improvement
- Nine basic principles for eliminating changeover waste
The book begins by outlining the tactical principles for improving the three phases of the changeover procedure. Next it demonstrates how to improve changeover on a processing line. All of the ideas presented are based on kaizen improvements, which require very little, if any, expenditure. Process razing and the implementation of one-piece flow are also examined as means to eliminate wasteful transportation and searching.
