I have a hard and fast rule for contractors: If I get even the slightest negative intel on a vendor I'm considering sending an RFP for a client's project, they're off the list immediately. Or if I've worked with them in the past, their performance has everything to to with their being considered a second time. Even the tiniest screw-up or mis-step is a deal-breaker because If I hire them as a subcontractor and they don't deliver, it's my responsibility as far as my client is concerned. They don't want excuses or blame. They want a successful outcome. Period.

But then, I'm not the Federal Gov't. grin
