RFIs and RFPs have a bit of an image problem. In theory, they bring structure and rigour to vendor selection. In practice, they often become unwieldy documents that take weeks to produce, elicit near-identical responses from every vendor, and leave the team no more certain than when they started.
The problem isn't the tools themselves. It's how they tend to get used. Here's how to use them effectively.
Understand what each one is actually for
The first step is using the right tool at the right stage.
An RFI, or Request for Information, belongs early in the process. It's a relatively lightweight way to gather high-level capability information from a broader pool of vendors, helping you understand the market before you start narrowing it down. Think of it as a scouting exercise rather than a formal evaluation.
An RFP, or Request for Proposal, comes later, once you have a shortlist. It asks vendors to respond in detail to your specific requirements, covering pricing, implementation approach, technical architecture, and integration capabilities.
Using an RFP where an RFI would do, or skipping the RFI entirely and going straight to an exhaustive RFP, tends to create more work for everyone without meaningfully improving the outcome.
Keep your requirements focused
One of the most effective things you can do when writing an RFI or RFP is resist the urge to include everything.
A requirements list that runs to hundreds of line items tends to produce one thing reliably: vendors who respond "yes" to all of them. When everything is a requirement, nothing is a differentiator. Responses look similar, scoring becomes difficult, and the document that was supposed to bring clarity ends up generating more noise than signal.
Instead, prioritise the requirements that genuinely matter to your organisation. A tighter, well-prioritised list will tell you far more than an exhaustive one, and it won't put vendors through unnecessary effort either.
Structure your document for clarity
A well-constructed RFI or RFP doesn't need to be long to be effective. It needs to be clear.
At a minimum, it should include a concise business context so vendors understand who you are and what you're trying to solve, a clear articulation of your key requirements ranked by priority, your integration landscape and any technical constraints, realistic implementation timelines, and the evaluation criteria you'll be using to assess responses.
The clearer your brief, the more useful the responses will be. Vendors aren't mind readers, and no amount of follow-up can fully compensate for a vague original document. Garbage in, garbage out, as they say in the herd.
Use responses to sharpen your evaluation, not conclude it
RFI and RFP responses are not a substitute for proper vendor engagement. They're a foundation for it.
Use what vendors tell you to sharpen your questions, structure your demonstrations, and focus your workshops on the areas where you still have uncertainty. The organisations that get the most out of these tools are the ones that treat the written response as the beginning of a conversation, not the end of one.
When used this way, RFIs and RFPs do exactly what they're designed to do: bring structure and transparency to a complex decision, and give you a consistent basis for comparing vendors fairly.
