If you have a task that will take 5 days and someone has the ability to veto the design of the deliverable at the end, you need to talk through the design before you commit to it. Spend a few hours working out what you'd do, then whiteboard it or even verbally run through it. It's worthwhile doing even if you wouldn't have ended up with wasted effort - other people can have helpful suggestions of things to look out for, or minor refactorings you might do along the way.
