Value-Stream Map Zones (from Perfecting Patient Journeys)
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.
