Unwritten grant management rule #1. This sounds like common sense but you would be surprised how many grantees decide to completely change their program once they receive funding. I’ve been in numerous meetings where the program manager says, “I know we said we’d do X but we’re going to do Y instead.” And my favorite is when the CEO says, “I need this money for something else.” Wait. What? Slight modifications are one thing, but a complete overhaul—especially without authorization—is something entirely different. Keep your word and keep to your plan.
