In the first months of my career I received an RFP from the US Coast Guard Academy. My initial excitement faded as realized it was for equipment totaling about $6,000. Despite the fact that they had several of these devices installed and there was no competition I had to make a detailed response that included posting a security bond. I spent a few hours in my response, won the business and probably netted less than minimum wage for my time and effort. I came to despise the RFP process whether it was for commercial or government entities.
When receiving an unsolicited RFP many sellers get excited. Some even delude themselves into believing their offering is a perfect fit and they have a great chance at winning the business.
