Sprint retrospective is one of five official events defined in The Scrum Guide™. This event should take place every sprint. There are sometimes sprints for which people don’t feel a need to have a retro. It could be because of a non-productive sprint, short sprint and an absence most of team members. In those situations organizing a retro meeting sounds like time wasting. In this post I’d like to take into account how scrum master can face it and encourage others to participate in a retro. I’ll present it basing on my experience in organizing these kind of meeting.
