Hi Joel,
Again as per the Best Practices.Nothing to be created in PRD,even if we create them in PRD for Power users its assumed as temprory and can be deleted at any time.
So if there are already deviations then you can go for deviations in this case as well but it wont be the Best Practice.
In our Project,we have done everything in DEV and transported to PRD,in case there were any very Minor changes at query level we have done in PRD and immedialtely replicated the same in DEV so that they are in SYNC.
