Hi everyone.
I've seen a lot of information on how to handle unplanned work, like adding in a buffer to each sprint to account of work that may come up that is not in the sprint backlog. However, I have come to understand that any interruptions that are acted upon during a sprint are not in fact following Scrum.
So to ensure that the essence of Scrum is alive and well in a team, does that mean that ultimately they should refuse any outside work on only stick to items in the sprint backlog. Especially if that outside work has nothing to do with their product?
