Sprint estimates we can trust
We always logged time in Jira, but the worklog numbers were whatever people remembered to type in, so our estimates never got better. With WebWork tracking on the same work items, the hours come from the work itself, and within two sprints we could see we were under-estimating backend Stories by about a third. What I didn't expect was the effect on retros — nobody argues about whose memory is right when the hours are sitting there per work item. We hit our sprint commitments a lot more often now, because we plan from hours we measured, not hours we guessed.
