This is something I've come up with. I think it should be part of every production.
This will save your team numerous hours and get things done smoothly and easily.
Assuming you have agile methods used in your production and you have a daily meeting where everyone one at a time says
what they have done
what they will done
what is blocking them.
This is where the things to be done next come up. This is where you as a designer should act.
What I do, I grab the people that are going to work on the new feature and use anything from a minute to half a hour to go through what they'll be doing. All the unclear parts get clarified and at the end of the meeting, everyone knows what they should do and everyone will be doing the same thing.
Also, this will point out any parts are not yet designed in detail and will get you occupied by designing what is missing.
This is highly recommended!
