The Unasked Question: Auditing a Service Reference for What It Omits

A reference call is one of the few points in a procurement cycle where an organisation outside the process can tell you something the proposal cannot. Yet in practice it is often treated as a closing ritual: a short conversation, a familiar set of questions, a favourable outcome that confirms a decision already taken. The call happens, the note is filed, and the committee paper records that references were "taken up and satisfactory".

That is a missed opportunity rather than a failure of diligence. The information is there. It simply tends to sit in the parts of the conversation that neither party has been trained to treat as relevant.

Why the standard script yields comfort rather than evidence

The conventional questions are well known. Would you work with them again? Did they deliver on time? How would you describe the relationship? Each invites a positive answer, and referees — who have usually been nominated by the supplier and who know they are being asked as a favour — generally supply one. There is nothing dishonest in this. It is simply how professional courtesy works.

The difficulty is that a reference nominated by the supplier is a curated sample. It tells you that at least one client relationship ended well, or is still going well. It does not tell you whether that outcome was typical, what it cost in management attention, or what happened when something went wrong. For a UK buyer assembling a business case, that distinction matters.

What goes unsaid carries weight

Experienced buyers tend to describe the same handful of patterns. None is conclusive on its own, and none should be treated as a red flag without corroboration. Together, however, they form a picture of the relationship that the headline answers conceal.

The pause before the positive. A referee who begins with a considered hesitation before reaching warm language is often deciding how much to say. The delay itself is not the signal; what follows it usually is. Listen for praise that arrives with a qualifying clause attached, such as a compliment about delivery followed by a remark about governance.

Praise that stops at the delivery team. Many references celebrate individual consultants or account managers rather than the firm. That is useful — it tells you where the value sits — but it also raises a question about what happens when those people move on. In a market where senior staff turnover is a live risk, a reference that praises people rather than systems is worth testing against the supplier's continuity arrangements.

The referee who no longer buys. Occasionally a call reveals, directly or by implication, that the relationship has ended or been reduced. A former client is not a poor reference; often the opposite. But the reasons for the change deserve attention, and a referee who has quietly stopped commissioning work will usually explain why if asked neutrally.

Answers given on behalf of the firm rather than the person. A referee who speaks in the language of a press release, rather than from memory, may be reading from an approved note. That does not invalidate the reference, but it does mean you are hearing the organisation's position rather than an individual's recollection.

A short script that opens the gaps without an interrogation

None of this requires confrontation. A few questions, asked plainly and in sequence, will usually do the work.

• "How did the engagement actually start, and would you scope it the same way again?"
• "What was the most difficult fortnight of the relationship, and how was it handled?"
• "If you needed the same work done again next quarter, what would you change about how you commissioned it?"
• "Who inside your organisation carried the management burden, and was that what you expected?"
• "Is there anything the supplier does less well than the rest of the market?"

The last question is the one most often skipped, and the one most likely to produce something usable. A referee who answers it with a specific, modest criticism is usually more credible than one who cannot find anything to say. Where the response is a flat denial of any weakness, note it and move on — pressing harder rarely yields more.

It also helps to ask about the reference rather than the referee's own experience. A supplier may have delivered excellently for one division while the wider group found the commercial terms inflexible. Enquiries about the reference's scale and the number of stakeholders involved will surface that.

Calibrating the reference to your own brief

A glowing account from an organisation unlike your own is not evidence about your engagement. Before the call, write down three attributes of your brief: its approximate value, the number of internal stakeholders who will be affected, and the regulatory or sector context in which it sits. Then test the reference against them.

A supplier that performed well for a single-site business may be untested on a multi-entity structure with a group audit committee. A firm that excels in a lightly regulated sector may have no experience of the reporting expectations that accompany a listed or public-sector client. And a reference from a client with a large in-house team may say little about a supplier's ability to work without one.

None of these mismatches is disqualifying. The point is to establish that you are comparing like with like, and to record the comparison in your decision note. Where the reference differs materially from your brief, ask the supplier to nominate a closer match. A firm confident in its delivery record will usually be able to.

Recording what you heard

A short written summary, taken during the call and circulated to those involved, is worth more than a memory of a pleasant conversation. Record the questions asked, the substance of the answers, the points of hesitation and any mismatch between the reference and your own brief. If you are operating under the Procurement Act 2023 or an internal governance framework that requires an auditable trail, this note becomes part of the evidence base. If you are not, it still gives the approving body something more substantial than an assurance that the call went well.

References are not a test that a supplier passes or fails. They are a small, imperfect sample of another organisation's experience, offered under conditions of professional politeness. The buyer's task is not to extract a verdict but to understand the conditions under which the sample was produced — and then to decide how much weight it can reasonably bear.
