Well, sometimes, in reality, it is cheaper to let things fail and fix it later ... not ideal, agreed. When working for an AU based telco giant with offshore teams in Asia, it was easier to just let them to do what they do (which is good work most of the times and not so great work sometimes, although no fault of the resources themselves - due to lack of training, comms issues, understanding ground reality etc etc) and remediate it AEST AM hours.
The reason I say letting things fail is cheaper is because, sometimes, given the lack of whatever at offshore centres, the mistakes made go beyond the point where it can be fixed. So, I know of managers who (including me, in some instances), advise, for things to be left where they were, and it will be tended to by someone here in AU during AEST AM hours.
Most of the customers are understanding (if explained properly within reason) and will accept a gift voucher or a credit to their bill etc as a peace offering for the inconvenience...
