Hello,
Our Sprints are 2 weeks long and that has worked pretty well so far (start Mondays and end Fridays). However our business provides requests (prioritization) on Tuesdays but many times that meeting is moved and aligning the Grooming/Planning could be a challenge. That plus the alignment of the releases (which are every other week mid-week) we typically need to take on the additional work in the current Sprint to make the dates.
We use estimates and my reports tend to be inaccurate due to the additions of the new requests. We tend to lower the amount of work for the Sprint knowing the new work will come in the coming days. We are a small team and are able to handle the work fine however from a reporting perspective its a challenge to share this with leadership as the line in the graph goes up (due to added story points).
thank you
