A couple of years ago, I did an agile project with a lot of iterations. At the end of each iteration we held a retrospective. All of these retrospectives had the same agenda and each agenda item was implemented the same way over and over again. Though we found aspects to improve every retrospective, it became a weekly grind. Starting an new project with over 40 sprints I was questioning myself: How can those retrospectives stay interesting for the team, even after dozens of sprints?
