It is common to invite case studies as part of an RFP response. They can help provide evidence of past experience and capability. But can we rely on case studies? Let's explore why case studies may not be a reliable source of proof.
Most procurement professionals review dozens of RFP responses each year. All of us will have encountered case studies submitted by respondents to showcase their capability. These narratives arrive with impressive metrics, glowing testimonials, and claims of transformative results for “similar” clients. On the surface, they may look compelling, but they are less verifiable than we might like. Could it be that case studies function more as marketing collateral than as reliable evidence?
To illustrate the point, consider this scenario:
In early 2024, a mid-sized Australian cleaning and facilities management provider faced imminent collapse. Over-expansion, unsustainable contracts, spiralling labour costs, and a dysfunctional procurement function had pushed the company to the brink of bankruptcy. Suppliers threatened to halt deliveries, key staff were leaving, and the board feared receivership within weeks.
Sam Whelan stepped in as Lead Procurement Consultant. Working virtually single-handedly with a depleted internal team, she conducted a rapid diagnostic review, uncovered multiple loss-making agreements, and personally renegotiated or terminated 27 high-value contracts.
Within nine months, the company had not only avoided bankruptcy but returned to strong profitability, generating $4.2 million in annualised savings. Cashflow stabilised, supplier confidence returned, and the business won several major new contracts. By early 2026, it was nominated as one of Australia’s Best Managed Companies, a remarkable turnaround widely credited to Sam’s expertise.
The CEO reportedly said: “Sam didn’t just fix our problems. She gave us a new commercial backbone. Without her, we simply wouldn’t be here.”
Actually, none of that is true. I made it all up. (Full disclosure: I do not misrepresent or lie about experience in my professional life. This was merely a literary device!)
You didn’t know it was fiction, did you? And if you asked for contact details of the CEO (let’s call her Alex), Sam could easily say she prefers to remain anonymous to avoid spooking her clients. There is no Alex, either, and no such dramatic rescue.
This simple demonstration reveals the core weakness of case studies in RFP responses. If even an experienced procurement practitioner can be momentarily drawn in by a well-crafted narrative, how reliably can evaluation teams use them to distinguish genuine capability?
It would be unfair to suggest that tenderers routinely fabricate content. Most suppliers are ethical and aim to present their track record honestly. However, the structure and purpose of case studies create systemic limitations that reduce their value as evaluation evidence. Here are six core problems procurement practitioners in both public and private sectors encounter repeatedly.
1. Low on verifiability Unlike audited financial statements or independently verified KPIs from live contracts, case studies are almost always self-reported narratives. There is rarely an objective third-party audit trail. Evaluators cannot easily confirm exact scope, actual costs incurred, real challenges overcome, or whether claimed outcomes were sustained beyond the initial project phase. In probity-driven procurement relying on the supplier’s word alone is simply not sufficient. Verifiability must be non-negotiable when selecting partners for critical services.
2. Built for persuasion, not verification Case studies are marketing documents first and evidence second. They are crafted to sell. Unflattering details are minimised or reframed as “learning opportunities.” Metrics are selectively chosen. Failures are airbrushed. The result is a highlight reel rather than a balanced performance report. This creates a fundamental mismatch with what procurement teams actually need: objective insight into how a supplier will perform on our contract, under our constraints, with our stakeholders. Persuasion belongs in sales; it should not masquerade as evaluation material.
3. Difficult to transfer to our specific context Every organisation differs in scale, culture, regulatory environment, legacy systems, risk appetite, and stakeholder dynamics. A glowing case study from a seemingly similar client in another jurisdiction or industry often falls apart upon closer examination. Suppliers naturally claim relevance, but without detailed mapping and evidence of adaptation, that relevance remains superficial. Evaluation teams waste valuable time attempting to force-fit someone else’s story to their own reality.
4. They rarely serve as differentiators Proposal teams focus on “win themes”: attributes that help them stand out. They identify “me-too” elements (capabilities all competitors can claim) versus true differentiators or discriminators. When applied to case studies, most responses present strong, positive examples that place the supplier in the best possible light. In scoring, case studies often result in respondents clustering within a point or two of each other. They rarely help evaluation teams make meaningful distinctions between bidders.
5. Drawn from pre-prepared libraries Most experienced suppliers maintain extensive libraries of case studies, pre-written for common scenarios and only lightly customised for each bid. The same core stories appear across multiple RFPs, with minor changes to client names or figures. This “one-size-fits-most” approach further dilutes applicability. What evaluators receive is seldom a bespoke demonstration of how the supplier solved a challenge exactly like theirs. It is a templated narrative designed to tick the “provide case studies” box.
6. Increasingly AI-enhanced or AI-written In 2026, generative AI has made things worse. Suppliers can input a brief into tools like ChatGPT, Claude, or Gemini and receive a perfectly structured, professionally worded case study in moments. Minor editing creates the illusion of relevance and authenticity. Submissions may sound highly tailored yet lack genuine organisational memory or hard-won experience. Evaluators might question whether the elegant prose they are reading reflects real delivery capability or sophisticated prompt engineering.
These weaknesses combine to make case studies one of the less reliable elements in RFP responses, yet they continue to consume significant evaluation time and effort.
What should replace them?
Fortunately, stronger, more verifiable alternatives exist and align well with good procurement practice in both public and private sectors.
Verifiable client references remain the gold standard. Insist on named, current or very recent referees who can speak to actual performance against similar scope, scale, and complexity. Require specific contact details and KPIs that can be validated independently. A structured 15-minute reference call often reveals more than ten pages of polished case studies.
Face-to-face or virtual capability demonstrations provide another powerful layer. Invite shortlisted suppliers to present live, solve a mini-scenario drawn from your project, or run a workshop on how they would approach key risks and constraints. Observing a team think on their feet, handle tough questions, and demonstrate genuine domain knowledge reveals true capability in ways written submissions rarely can.
Performance data from current or recent contracts -where available- offers objective evidence. Request summaries of SLA performance, variation history, customer satisfaction scores, or audit outcomes that can be cross-checked.
The overarching principle is triangulation. Try to avoid relying on a single source. Cross-reference claims in the submission against references, live demonstrations, site visits (where practical), and any publicly available performance information. When multiple independent sources align, confidence increases significantly. When they diverge, red flags appear early.
Probity and legal implications
For public-sector practitioners, the probity dimension is especially important. Over-reliance on unverified case studies increases exposure to “puffery”. This are vague, exaggerated claims that no reasonable person would take literally. The famous Red Bull “gives you wings” campaign led to a US$13 million class-action settlement, even though the company maintained its marketing was not dishonest. Courts drew a line between harmless hyperbole and statements that crossed into misleading territory.
Under the Australian Consumer Law (particularly s 18 prohibiting misleading or deceptive conduct in trade or commerce), factual claims about past performance, capabilities, or outcomes are treated as representations upon which the buyer may reasonably rely. If those claims prove false or create a misleading impression, suppliers risk penalties, damages, or contract rescission. Silence, half-truths, or selective presentation can also qualify.
In tender or RFP settings, overstated or unverifiable claims about cost savings, project outcomes, or capability carry real legal risk. Finding out after contract award is too late. Smart procurers design evaluation processes that minimise reliance on material that cannot be independently verified.
Practical recommendations for 2026
Consider these adjustments when drafting or reviewing tender documentation:
Reduce or remove heavy weighting on “provide case studies.”
Replace with a clear requirement for 2–3 recent, relevant references including named contacts and specific, checkable performance metrics.
Allocate meaningful evaluation weight to live presentations, workshops, or scenario-based demonstrations for shortlisted suppliers.
Explicitly state that all claims must be capable of independent verification and that misleading information may result in disqualification.
Update internal evaluation templates, probity plans, and risk registers to reflect this evidence-based approach.
These changes require minimal extra effort but deliver substantially better decision quality. Genuine high-performing suppliers will welcome the shift, as it rewards real capability rather than marketing polish. Those relying on generic libraries or AI shortcuts will find the process more demanding. This is precisely the outcome we should encourage.
As procurement professionals our responsibility is to secure optimal outcomes for our organisations while upholding the highest standards of governance and probity. Let's request evidence that can be verified and focus on methods that reveal authentic capability. The suppliers who truly deliver value will rise to the top, and our organisations will be stronger for it.
