Doug,

Fabulous idea for those of us in the trenches.

Also need one for the bureaucrats so they understand why the processes are important.

"No Clean" is low solids.  In some applications No Clean is as bad as the other types of fluxes, e.g., high voltage applications like 25 kV.

To add to Günters comment the person needs to know the end product requirements.  Is the board to be in dielectric oil, high voltage in air, or encapsulated in RTV or Epoxy?  I have had issues with flux inhibiting the cure of RTV.

The advantages of batch (dishwasher style) cleaning versus inline cleaning and the down side to both.  We have seen incursion of "stuff" into chips causing failures especially optos.
