A dedicated delivery team sits between augmentation and full outsourcing, and it is the model most often set up incorrectly. The mistake is to staff it like augmentation — several individuals supplied against role descriptions — while expecting it to behave like an outsourced team with its own delivery accountability.
That arrangement has no owner. The supplier is accountable for supplying people, the client is accountable for direction, and the delivery outcome belongs to neither. When it slips, both parties are correct that it was not their fault, which is the clearest signal that the model was set up wrong.
