To give focus to the continuous improvement of the team, we want to identify longer term goals, longer than 1 or 2 sprints, but not too far ahead in the future.
As a facilitator, you can help the team to identify (possibly through actionable metrics) the things that slowed down the team, and the things which made the team faster in the past Sprint.
Ask the team to come up with post-its for each of these categories:
Brakes: Things which are slowing the team down.
Accelerators: Things which the team thinks makes them faster.
Make sure the team is reflecting on the reasons why either Brakes or Accelerators happen and identify the things which need to be addressed or leveraged. Once these are clear, the facilitator asks the team to define a goal (which could be in the far future) either to focus on things they would like to amplify or by removing things which are slowing them down.
Once the goal has been defined, the team will have to identify the criteria that will prove that the Goal has been reached, something measurable (e.g: 70% test coverage, less than 2% new bugs…).
Write a post-it with the Goal, and the measurement criteria a place it on Try (indicating the team is going to try to reach that Goal).
