Mapping the Total Value Stream defines and elaborates on the concepts of value stream mapping (VSM) for both production and transactional processes. This book reshapes and extends the lessons originally put forward in a number of pioneering works including the popular, Value Stream Management for the Lean Office. It reinforces fundamental concepts and theoretical models with real-world applications and complete examples of the value stream mapping technique. To educate VSM mappers on the specific mechanics of the technique, the text provides in-depth explanations for commonly encountered situations.
The authors also provide a more complete perspective on the concept of availability. While they discuss availability of equipment in transactional processes, they extend the concept by elaborating on availability as it applies to employees. The calculation of process lead time for work queues is taken to an advanced level - not only is the calculation of this lead time explained, but the text also covers the very real possibility of having more work in the queue than available time.
While previous books have focused on only production process VSM or transactional process VSM, this work meets the real needs of both manufacturers and service sector organizations by dealing with both types. It goes beyond explaining each scenario, to teach readers what techniques are commonly applicable to both, and also explains areas of difference so that mappers will be able to readily adapt to whatever unique situations present themselves.
