When unwanted incidents occur, the opportunity presents itself to analyze what went wrong and to put in place mechanisms which reduce the chance of a similar incident recurring.
It's not sufficient just for the people in the team to learn from incidents, we also want the team as an entity to learn, ensuring that incidents do not repeat within the team, even if the people have since moved on.
Use tools like blameless post mortems to understand, communicate and learn from what went wrong. Then, operationalize post mortem findings by adding to or amending coordination mechanisms like responsibilities, skills, processes, checklists, policies, etc.
