I ran a product management team in a fairly large B2B cloud-software company for one 5 years. Enterprise RFPs are a huge pain. And yes, we could immediately tell when one of the RFPs that we were working on was written by a competitor. We also tried to influence the RFP for a customer. When we gotten fairly large we had a dedicated group of people whose primary responsibility was to respond to RFP from a library of questions.
