An iteration process has mechanisms in place to help steer teams. Of all of the practices that support iteration, regular sprint reviews help teams and product owners get the feedback that they need to improve their performance. Reviews are also one practice that I've noticed that teams slack off on, especially when they are first starting out.
A common rationale for not having an iteration review are that there isn't enough to show. When the team is not making progress is the most important time to review progress with the product owner and evaluate how the project is doing and what needs to change. While the first review may be difficult, if everyone on the team is committed to a successful project, a review of less than successful sprint can have many positive consequences:
- The product owner many be more impressed my the progress than the team thought, freeing the team to take more ownership of their work.
- The product owner may be better able to understand that the backlog might be the wrong size as the team compares the results of sprint to the backlog, providing the team with the data it needs to have a more attainable backlog.
- The team may recognize things it can do to work more effectively.
As you identify issues it's also important to review progress on these issues at subsequent reviews. If you let them drop then the people at the review will come to understand that the review feedback is part of an empty exercise. It's OK to acknowledge that a review item wasn't acted upon, or is no longer necessary. But you should discuss each action from a review at the next one.
While this sounds easy, there are some challenges including establishing trust between the product owner and the team, and developing an understanding that they share the same goals. You need to be able to talk about what's not working, and figure out how to make it work, not just assign blame. If the team and the product owner is new to Scrum, and the project is new, you may have to start with a premise of trust. This is hard, but with the regular feedback of a review each sprint, the stakeholders will be able to readily evaluate everyone's dedication to the project.
It's very important to discuss what went well, preferably before covering what needs to be improved. (I tend to favor the attitude I learned from patterns writers workshops.)
Some suggestions for those struggling with agile:
- Have reviews at the end of each Sprint, using your backlog as an agenda.
- Show the work done in the simplest way possible.
- Collect feedback both on the work and the process, and identify things that went well and things to improve.
- Save the list of things to improve for the next review, and be sure to discuss them.
