The current RFP (Request for Proposal) process is broken. It is not serving the customer, and it is not serving the vendor or service provider.
Before discussing the shortcomings of current practices with respect to the RFP, we should say that laws and regulations require some agencies, companies, and organizations to file highly detailed documents covering nearly every aspect of the product or service. If you have these legal or regulatory requirements, then there isn’t much you can do to change how you approach the RFP document itself. Even so, there may be additional aspects of the process for you to consider.
If, on the other hand, you do not have these requirements, it’s time for you to ask, “Why are we doing it this way?”
