Adapting and incorporating the After Action Review process could improve your work, especially if applied to a large project (such as completion of a big investigation or significant crime problem solving effort). The process helps you identify what can be improved for the next time.
"An AAR is centered on four questions:
What was expected to happen? What actually occurred?
What went well and why?
What can be improved and how?
An AAR features:
An open and honest professional discussion
Participation by everyone on the team
A focus on results of an event or project
Identification of ways to sustain what was done well
Development of recommendations on ways to overcome obstacles"
