List ideas that the team should be doing but are not doing, innovative ideas worth discussing to address current problems.
List ideas that are not delivering results or might be driving people a little crazy – such as unnecessary bureaucracy.
List ideas that are creating value or should not be dismissed yet because the outcome is not yet known.
As best practice, remember to set the stage and ensure that people are reminded that is not a process of blame, but for identifying areas for change. If you have run this retrospective method several times before, you should see greater fidelity of ideas. If there are recurring items, this should be a treated as a red flag.
