What is a retrospective?

Retrospective: A retrospective is a meeting at the end of a piece of work where the team looks at how it worked, not what it built, and picks changes to try next time. In Scrum it closes every sprint.

Also known as retro, sprint retrospective.

The Scrum Guide puts the purpose plainly: to plan ways to increase quality and effectiveness. The team looks at people, interactions, processes, tools and its Definition of Done, and agrees what to change.

How a retro works

Most retros follow the same three steps:

  1. Gather input: what went well, what didn't, what to change.
  2. Group and discuss: cluster the input into themes and talk about the big ones.
  3. Pick actions: one to three concrete changes, each with an owner, to try in the next sprint.

The Scrum Guide caps the retro at three hours for a one-month sprint, and shorter for shorter sprints.

Running the input step in Slack

Collecting input in the meeting means the loudest voices fill the board. Collecting it beforehand, anonymously, gets everyone's view and saves meeting time.

With Simple Poll, post an anonymous survey (Premium) a day or two before the meeting with short text questions, and close after so it's finished when you meet. In the meeting, group the answers into themes, count them, and quote a few word for word. Then put the top suggestions to a ranked vote to pick the first action. Teams that are fully async can run the whole retro this way.

The mistake people make

Ending without an action, or with ten. Pick one to three changes, name an owner, and open the next retro by checking whether they happened. If the same problem shows up three retros running, the actions aren't working.

Questions

Should retro input be anonymous?

Usually, yes. People name problems more readily without their name attached, especially problems involving colleagues or managers.

Is a retrospective the same as a post-mortem?

They're related. A retro is regular, at the end of every iteration. A post-mortem usually follows one incident or project.
