One trick I’ve used is quite simply having five things on at once. You keep notes of where each project is, and work to get each one blocked. When they get unblocked, you switch to that thing until it’s blocked again. There will be people who insist that you should “focus on the most important thing” but if it’s blocked what’s the point? The other thing to do is make a lot of friends in related departments. It’s amazing how much faster things will go when someone does you a favour. Expect to be doing favours in return.
