Office jargon: 'oven-ready' and 'staff buy-in'

A friend of a friend of The Engine Room works at the Home Office, and she was recently told at a conference of managers to ensure that all policy delivery was "oven-ready before getting staff buy-in".

What does oven-ready mean? That something is "ready for people to work on immediately rather than being a work in progress," according to our mutual friend.

And staff buy-in? "Getting people to support any new policies rather than having them do something they think is stupid."
