Value Stream Mapping is a technique used within business and industry to analyze and design material and information flows. A full description may be found at Wikipedia article on Value Stream Mapping.

These stencils (both metric and US units) contain shapes and symbols for creating Value Stream Map diagrams very quickly within Microsoft Visio, ideal for illustrations, presentations and management overviews.
The template controls routing of connectors. The timeline segment shapes just snap together, double click the shape to edit the time. The Timeline total shape has two time edit sections, select the area then use the text tool to edit the time totals.
