"If people really want to help then it shouldnt matter if we ask them to do some other work beyond their "prefered" field."

"If we really need people to help then it shouldn't matter if we let them focus on their "prefered" field."

Being a smart-ass aside, an update to the IMM process would help if it has been streamlined or changed.

I don't envy your or the other IMMs position right now, but if you can get someone that can code reliably (and I don't mean me atm), then please get what coding you can out of them with the time they can contribute. If they flake or burn out in 4 months, you still have something.
