Four teams in one department.
All four Sprints started and ended at the same time.
Four different burndowns.
Team B got up late in the Sprint and filled the Sprint backlog after the Sprint started.
Team A, C and D have the typical slow start for the Sprint getting their teeth into the stories.
Team A waited till the end to do a cliff jump and close most of the stories.
Team B did not manage to finish many of the stories that were planned for the Sprint.
Team C had a constant burndown throughout the Sprint.
Team D was slow till the middle of the Sprint and then picked up speed towards the end of the Sprint.
We tend to analyse Burndowns in teams. Are we analysing the Valueups?
