The "Creating and Interpreting Cumulative Flow Diagrams" post from 2006 explains a simple way to visualize and measure flow. The only data required to construct a cumulative flow diagram is state transition timestamps. A cumulative flow diagram can help identify bottlenecks, find resource constraints, and estimate delivery times for customers. http://leadinganswers.typepad.com/leading_answers/2006/09/creating_and_in.html http://leadinganswers.typepad.com/leading_answers/2006/09/cr... This is the single most useful process analysis tool I've discovered in a decade of analyzing engineering development processes (at least when humans are responsible for tracking the data).
