Outsouring over time starts to create its own bureaucracy bloat. It’s the modern corporate version of one of the observations of C. Northcote Parkinson: “Officials make work for each other.” As Clive describes, the first response to the problems resulting from outsourcing is to try to bury them, since outsourcing is a corporate religion and thus cannot be reversed even when the evidence comes in against it. And then when those costs start becoming more visible, the response is to try to manage them, which means more work (more managerial cost!) and/or hiring more outside specialists (another transfer to highly-paid individuals).
