Hi Community,
My department decided to clean up the teams backlogs (which have between 200-400 items) so that the teams can focus on the future work rather than having all the items hoarded from X years ago. There's a usual attachment to the items that were created X years ago so my suggestion was to, firstly, categorise the old items vs. more forward looking ones and then start rejecting the ones that are no longer needed and will never be worked on.
We planned to do this by having 2 separate boards: Old Backlog (will include items created longer than 1 year ago and exclude tech debt items with a specific label) and Forward-looking Backlog (will include items created less than a year ago and tech debt items). However, this causes a problem in sprint reports due to the filters being used where the sprint reports are incorrect and under-report the numbers of story points etc.. Ideally, we'd want to still see the historical sprint reports with correct values that were used in the original sprints.
Has anyone ever come across this problem and is there any way to keep the sprint reports with the old values?
