There is a moment in almost every enterprise procurement process I have been part of — usually somewhere between the third stakeholder workshop and the first draft of the requirements document — where I notice something quietly wrong. The language of the RFP has begun to mirror the language of the incumbent vendor's own marketing collateral. A capability described in suspiciously precise numerical terms. An integration requirement that exactly matches one proprietary API. An evaluation criterion that rewards years of installed-base experience in a way that no challenger, however capable, could honestly claim. It is rarely deliberate sabotage. It is rarely even conscious. And that, I have come to think, is precisely what makes it so durable and so hard to correct. The incumbent advantage in procurement is not a conspiracy; it is a structural feature of how large organisations gather information, and understanding it as such is the only way to do anything useful about it.
How the information asymmetry begins ¶
The incumbent vendor has been in the building for years. In that time they have briefed product roadmaps, run lunch-and-learns, sponsored internal user groups, and — most consequentially — provided the vocabulary through which your organisation talks about the problem the new procurement is meant to solve. When a buyer organisation sits down to write requirements, they draw on the knowledge of the people closest to the domain. Those people have spent years inside the incumbent's mental model. They learned what 'workflow orchestration' means from one vendor's documentation. Their instinct for what a reasonable SLA looks like was calibrated by one vendor's contractual norms. None of this is corruption. It is simply how situated knowledge works. But the effect is that the RFP, before a single challenger has even seen it, is already written in the incumbent's dialect.
The three mechanisms worth naming explicitly ¶
I find it useful to name these mechanisms rather than leave them as a vague suspicion of bias. The first is specificity laundering: a requirement is written at a level of technical precision that only the incumbent can meet, but the precision is framed as rigour rather than preference. 'Support for SAML 2.0, OAuth 2.0, and legacy Kerberos token pass-through in a single authentication flow' sounds exhaustive and technology-neutral; it may also be an exact description of one platform's current implementation. The second is timeline compression: the incumbent has a running system and can mobilise a polished demonstration in days; challengers need weeks to stand up a credible proof of concept, and if the evaluation window is tight, the comparison is structurally unfair. The third — and I think the most underappreciated — is reference-case weighting: scoring rubrics that assign heavy marks to prior deployments in your specific industry, at your specific scale, on your specific infrastructure stack. The incumbent has all three; nobody else has any.
What the RFP document itself tends to reveal ¶
If you want to audit a draft RFP for incumbent shaping, read it against the incumbent's own public materials — their product documentation, their case study library, their conference keynotes from the past two years. Look for requirements that echo phrasing found nowhere in analyst reports or industry standards but that appear verbatim in vendor white papers. Look at the weighting structure: if 'proven migration tooling' or 'native integration with [specific platform]' carries twenty percent of the total score, ask who benefits. Count the number of requirements that are forward-looking — things the incumbent's roadmap has promised but not yet delivered — versus things they demonstrably do today. A requirement written to a future release is a gift wrapped in neutral language. I have seen scoring sheets where the incumbent, scored honestly against its own current product, would not have cleared the qualifying threshold.
The role of the incumbent's account team in the drafting process ¶
I want to be precise here because I think procurement professionals sometimes feel they are being accused of bad faith when this conversation comes up, and that is neither accurate nor useful. The mechanism is usually something like this: the buying organisation's project team, under time pressure, asks the incumbent for help scoping the requirements — because the incumbent knows the domain and can move quickly. The account team obliges, professionally and enthusiastically. They provide draft requirements language, suggested evaluation frameworks, even scoring rubric templates. They have done this many times and the documents are polished. The project team, grateful and overworked, incorporates large portions of this material. By the time the RFP goes to market, it has been materially authored by the vendor it is ostensibly being used to evaluate. This is not hypothetical; I have seen the tracked-changes documents.
A working framework for identifying and correcting the bias ¶
The correction is not complicated, but it requires deliberate process. First, before any vendor is engaged in requirements gathering, conduct a source audit: for every requirement, document where the language originated and who contributed it. Requirements sourced from the incumbent's materials should be rewritten by a neutral party — an independent consultant, an internal architect with no vendor relationship, or synthesised from analyst frameworks like Gartner's Magic Quadrant evaluation criteria, which, whatever their limitations, are written without incumbent input. Second, test every precise numerical threshold — response times, throughput figures, integration counts — by asking whether the number came from a business need or from an existing system's specifications. If a stakeholder cannot explain why 99.95 percent availability is the requirement rather than 99.9 or 99.99, the number probably migrated from an SLA the organisation is already living with. Third, run a challenger simulation: give a vendor you consider genuinely strong but unproven in your environment the draft RFP and ask them, privately and candidly, to identify every criterion that disadvantages them structurally rather than on merit. Their answers will locate the bias faster than any internal review.
On the question of whether incumbents deserve their advantage ¶
I want to hold this question seriously because I think it gets dismissed too easily. Switching costs are real. Integration debt is real. The institutional knowledge embedded in a long-running vendor relationship — the account manager who knows which of your internal stakeholders is actually the decision-maker, the support team that has seen your edge cases — has genuine value that a clean-slate evaluation will not capture. There is a legitimate argument that an incumbent who has served you well for eight years and has adapted to your environment deserves a structural preference in evaluation. My objection is not to incumbents winning; it is to the evaluation process being shaped in ways that prevent the buying organisation from knowing what it is trading away. If you are going to give the incumbent an advantage, do it explicitly, with a named preference weighting, reviewed and approved by governance. Don't let it happen by default through contaminated requirements, and then pretend the outcome was a neutral, evidence-based decision.
What this looks like in practice, and where the difficulty actually lives ¶
The hardest part of applying any of this is not analytical — it is political. The stakeholders who contributed incumbent-shaped language to the RFP are often the same people who will evaluate the responses and who have the deepest subject matter expertise. Telling them their requirements are biased is, in effect, telling them their professional judgment has been colonised by a vendor relationship, which is not a conversation that tends to go well. What I have found useful is to frame the correction not as a critique of what was written but as a resilience test: we are stress-testing the requirements to ensure no capable vendor is accidentally excluded. That framing lets people participate in the correction without having to admit the original problem. It is a small rhetorical move, but in my experience it is the difference between a process that actually changes and one that produces a revised document with the same structural biases rearranged into new sentences.
The incumbent advantage is persistent not because procurement professionals are naive or captured — most of them are neither — but because the processes through which we build shared knowledge inside organisations are themselves shaped by the vendors who have been there longest. Noticing this clearly, without converting it into a morality tale about vendor bad faith, is the first and most necessary step. The rest, as I have tried to lay out here, is patient, specific work.
