Progress is easy to visualize when we use the yardstick of calendar time. My wife and I spent 17 days in Europe. There are 197 shopping days until Christmas (as of June 12, 2018) — I expect presents this year. How long it takes to deliver a piece of work, in days, is something nearly every human can understand. Over the past few months, I have been cataloging questions I have heard.

Cycle time metrics are ways to generate answers to ‘how long’ questions in a manner that is valuable and predictable. (more…)


The simple cumulative flow diagram (CFD) used in Metrics: Cumulative Flow Diagrams – Basics  and in more complex versions provide a basis for interpreting the flow of work through a process. A CFD can help everyone from team members to program managers to gain insight into issues, cycle time and likely completion dates. Learning to read a CFD will provide a powerful tool to spot issues that a team, teams or program may be facing. But to get the most value a practitioner needs to decide on granularity, a unit of measure, and time frame needed to make decisions.
