The remaining challenge is to find the right platform given what you’re looking for and what you can spend. You have three options: (1) Phone a friend, (2) Conduct market research, and (3) Issue a Request for Proposals (RFP). In theory, they’re all fine, but the first is limiting, and the second requires a lot of effort. Exploring is ideal... why not let others do the work for you by identifying themselves? An RFP (or its close cousin, a Request for Information) is your best chance to see the breadth and depth of the market. You should cast a wide net. If you restrict the field to just the “popular” vendors, you’ll miss products that may meet your unique needs best.
