All epics, and cards that stand alone of epics, must be validated to determine if they achieved the outcome that they were intended to. Did they produce the measure of success that we wanted and ideally this measure of success is defined in terms of one of our key performance indicators. Did we move the needle for that KPI in the direction, and the distance, that we said it would go?
Failure to achieve the measure of success that we wanted isn’t a problem. Failure to take the time to learn from the validation and determine next steps to continually improve is. No validation means we have no build, measure, learn cycle, which means we are repeating the same old every day and not improving. Validation takes work, it needs to have points and it needs to be queued in the backlog. It is not an afterthought that we quickly discuss during retrospection. It is the most valuable work that we can do. And the results of it can’t be acknowledged and forgotten. The lessons learned must be queued as ready ready backlog for the next or current epics. If there are no cards on the board that meet this criteria then we are not continuously learning and improving, we we are wandering.
