Walking the shop or office floor with a paper and pencil to collect data and observe actual conditions is how value-stream mapping (VSM) is done. But for a long time, members of the Lean Community have been sharing these hand-drawn maps by creating their own electronic templates from scratch in various software programs. eVSM makes the process of turning hand-drawn maps into electronic ones easier and faster.
As a companion – not a substitute – to paper-and-pencil mapping, the software allows lean practitioners to easily create, modify, and disseminate electronic value-stream maps.
Developing a current-state map creates a common understanding of how things really work today in the value stream (not necessarily what the documentation says or some might believe) so that the stakeholders can work together to identify and address problems and make improvements. Remember, see together, learn together, act together.
All value-stream maps are laid out in a horizontal format. They capture major categories or zones of fact finding. We find it helpful to think about value-stream maps in terms of the following six zones: customer, supplier, processes, information flow, process data, and a timeline and summary.
Perfecting Patient Journeys, from which these guidelines are taken, is a guide to value-stream improvement for leaders of healthcare organizations who want to implement lean thinking and engage employees in solving problems in order to deliver better and more efficient care. Readers will learn how to identify and select a problem in the performance of a value stream, define a project scope, and create a shared understanding of what's occurring in the value stream. Readers will also learn to develop a shared vision of an improved future, and hopefully work together to make that vision a reality.

Excerpted essay from Seeing the Whole Value Stream
This essay demonstrates how a second-tier supplier convinced much larger partners to embrace collaborative thinking about their shared value stream and rethink offshoring in light of the true system costs.
"Acme Alliance is a “job shop” aluminum die-casting company with a factory and headquarterslocated north of Chicago. We also have nearly identical facilities in Brazil, China,and Portugal that are able to make the same parts with the same molds on similar machines.This gives our firm a special insight into differences in total cost for products delivered tocustomers from different manufacturing sites across the world."
