Actionable Agile Metrics for Predictability
About this book
Vacanti makes the case for flow metrics over story point velocity. Covers cycle time, work in progress, throughput and their relationship through Little's Law, then the charts that make them usable, being the cumulative flow diagram, the cycle time scatterplot and the histogram. The central practical point is forecasting from cycle time percentiles rather than from estimates, and the book is specific about the assumptions that must hold.
