Cycle time?

In Part 1 we examined Work in Process and Story Escape Rate.  These two metrics are powerful but are not sufficient to provide a full picture of the flow of value through a process.  We continue with four more metrics to complete the pallet.

Cycle time?

In a recent discussion of Agile metrics, I was asked whether there was a difference between cycle time and throughput.  The simplest answer is that they “feel” similar. Many in software measurement define throughput as the number of units of work (UoW) delivered per unit of time; while cycle time is the amount of time per unit of work (as defined in Actionable Agile Metrics).  The two metrics are the reciprocal of each other. These definitions are functional; however, the cycle time metric is an abridgment of the how the measure is defined in the broader process measurement world.  With the profusion of lean six sigma black belts in the software measurement world lack of precision in the definitions can lead to comical misunderstanding.  Cycle time, with and without lead time, tell interesting but very different stories and are both useful.   (more…)

Today we tackle Chapter 5 of  Daniel S. Vacanti’s Actionable Agile Metrics for Predictability. Chapter 5, Flow Metrics and CFDs combines the concepts of flow metrics and cumulative flow diagrams (CFD). Cumulative flow diagrams are powerful data visualization techniques, combined with flow metrics the power becomes more evident. Buy your copy today and read along! (more…)
