Imagine you were given a project a few months back, due to be finished on the 5th of December. Imagine that despite good intentions and a few aborted attempts, you haven't actually started it yet. Imagine that you have blagged your way through two consecutive monthly reviews of the project using classic lines like: "Everything is going to plan so far and I'm really pleased with the progress we have made to date". Imagine that it is 17:05 on the 4th of December and you still haven't started.

What do you do?
