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.
