Of course you would not expect every sprint to have a perfect burndown. You would not expect to complete every story in every sprint (my goal has always been 90% or greater stories complete), but if you are finding yourself with many “overhanging” stories each sprint there are a number of things that you can do to diagnose and fix the issue. In this particular post, I am going to discuss problems with time and hours.
There are three things that can go wrong with hours:
- The number of hours the individual estimates for capacity is too low.
- The number of tasks identified is incorrect (not enough tasks identified).
- The number of hours associated with each task is too low.
