Your team’s velocity is going up. Story points completed per sprint keep climbing. Everyone feels productive.

So why does it still take six weeks to get a feature into production?

Because velocity measures effort, not outcome. Effort is easy to game. Estimate higher, deliver the same work, and the chart goes up. Everyone’s happy except the customers who are still waiting.

Cycle time measures something harder to fake. It’s the clock that starts when someone says “let’s build this” and stops when it’s live in production. Every handoff, every bottleneck, every “waiting on review” shows up in that number.

I worked with a team that had great velocity numbers but terrible delivery. When we started tracking cycle time we found a three-week gap between “code complete” and “deployed.” The code sat in a QA queue that nobody was watching. Velocity didn’t catch it. Cycle time made it obvious in a week.

If you only track one engineering metric, track how long it takes for an idea to become working software in a customer’s hands. Everything else is a vanity metric.
