According to the community, when a developer finishes their work in the last few hours of an iteration, they must try to help their teammates finish their work. Otherwise, it’s recommended they help prepare the next cycle of work, analyzing the next user stories, refactoring a piece of code that could be better implemented, or writing tests. It is not advisable for a developer to get a new user story started if they won’t be able to finish this in the same cycle. However, this first approach is not always possible because user stories can be underestimated or something can happen that would delay the delivery of the user story.

A second alternative is to split the user story into two smaller ones and develop the one that can be finished on time. The first user story’s points are credited in the current cycle, the second one’s are credited in the next cycle. This approach improves the visibility of what was done in the current cycle. However, it hurts the agile philosophy, in some way it would be a delivery without business value for the customer.

The third way is for the unfinished user story to go to the next cycle with the original estimate. When it gets completed, the user story’s full effort estimate gets credited to the velocity of the new iteration. This could skew the average velocity metric, so be careful, because this is important to the Product Owner (PO) for forecasting and planning. Also beware to not have a bunch of backlog items almost done: one user story delivered has more value than a lot of user stories 90% complete.

How do we do it?

Usually, we use the first and third approaches in the following way:

  • We try to concentrate efforts on work that is closest to delivery. As soon as a developer finishes the first US, they will verify if someone needs help with finishing a task or if some user story in the current cycle has defects that need to be fixed. Keeping the work-in-progress as low as possible helps to focus on what matters most. This process is repeated until the end.
  • If this list is empty and the cycle is almost over, the developer looks for the smallest or most valuable user story (depending of project’s context) to be done.
  • If the user story has not been finished by the end of the cycle, this US shifts to the next cycle with the original estimate. However, when we plan the next cycle, we’ll consider just the missing points to finish the US.
  • When this US gets finished, we credit the whole user story’s estimate in our velocity.
  • If the developer after resuming the work on the US in the next iteration realizes that the user story was overestimated or underestimated, usually, we don’t change the estimate on the story itself, but we update our ruler score with the real estimate, as lesson learned.

Note that we do not use these exact steps every single time, everything depends and adapts according to the context of the project or the moment. The most important thing is you prioritizing to deliver maximum business value to the customer.
