We have an approach we use within the organization of “lessons learned”, and we have already had one of those exercises on this, both to understand what factors led to the error in the first place and to make sure that we have a good approach for quality control going forward, so that we don't repeat the error. We do that sometimes after large implementations when things go well, and sometimes when they don't go as well.
We've already had the opportunity to think through what caused the original error, and what things we will be doing differently in the future.
