Actionable Agile Metrics for Predictability (2015) by dan-vacanti is the definitive guide to flow-based metrics for Kanban and Agile teams. Vacanti, who helped develop the kanban-method at corbis alongside Anderson and corey-ladas, drew on his deep experience with flow systems to create a comprehensive framework for using cycle time, throughput, and work-in-progress data to achieve predictability.
The book extended Anderson's manage-flow and fitness-criteria concepts into a rigorous analytical framework, providing the measurement foundation that the kanban-method needed for data-driven improvement. Vacanti later helped develop the "Professional Scrum with Kanban" class with Scrum.org (2017), bridging the two communities.
