Before the Proposal Lands: A Short Comprehension Check for UK Supplier Shortlists

Why ask for three sentences at all
Most UK buyers do not suffer from a shortage of proposal text. They suffer from late clarity. A document can be polished, compliant and still fail to show that the supplier has understood the commercial problem. Before committing time to a full evaluation, ask each shortlisted supplier to provide three plain sentences: the problem, the success measure and the biggest delivery risk. The purpose is not to replace the proposal. It is to test whether the supplier can think before it writes.
At CLI Ltd, this is a useful discipline in commercial partnerships: it moves the conversation from presentation to comprehension.
The three sentences, defined
The first sentence should state the problem in the buyer's terms. Not the supplier's service catalogue, not a restatement of the specification, but the operational or commercial difficulty the contract is meant to resolve.
The second sentence should define success in a way that could be checked later. A named outcome, a service level, a cost position, a timescale or a customer result is acceptable. 'Improved efficiency' on its own is not.
The third sentence should name the biggest delivery risk and say who owns the response. The risk may sit with the buyer, the supplier or a third party. What matters is that the supplier can distinguish a risk from a general worry and can attach responsibility to it.
Keep the format fixed. Three sentences, no bullet lists, no appendices. The constraint is the test.
A simple scoring method
A three-person panel can score each supplier without turning the exercise into a second tender. Use a 0-2 scale for each sentence:
| Test | 0 | 1 | 2 |
|---|---|---|---|
| Problem | Restates the service or uses generic language | Partly reflects the buyer's issue | States the buyer's problem in plain terms |
| Success measure | Vague or unmeasurable | Measurable but incomplete | Specific, checkable and tied to the contract |
| Delivery risk | No clear risk or no owner | Names a risk without ownership | Names the main risk and the responsible party |
A total of 5 or 6 suggests the supplier should proceed to full proposal review. A score of 3 or 4 warrants a clarification call. A score of 0 to 2 is a warning that the proposal may be well written but poorly grounded. Record the scores and the reasons. The reasons matter more than the number.
Red flags to watch for
The first red flag is a supplier that answers with a paragraph when asked for a sentence. Brevity is part of the test. If the supplier cannot compress the brief, the evaluation team will carry that ambiguity into mobilisation.
The second is a success measure that only the supplier can verify. If the buyer cannot check the result without relying on the supplier's own report, the measure is weak.
The third is a risk sentence that names a risk but not an owner. 'Resource pressure may affect delivery' is an observation. 'Resource pressure is the main risk; we will hold a named mobilisation lead and report fortnightly' is a response.
The fourth is a problem sentence that mirrors the specification word for word. That can show compliance, but it does not show understanding.
The fifth is a supplier that refuses the format because the proposal will explain everything. A full proposal can explain method. It cannot excuse a failure to understand the brief at the start.
A short worked example for 2026
A UK buyer is shortlisting suppliers for a regional facilities service. The brief requires improved response times across several sites and better management information for the buyer's property team.
Supplier A writes: 'The problem is that facilities services need to be delivered efficiently. Success will be improved service performance. The main risk is mobilisation.'
Supplier B writes: 'The problem is that response times vary by site and the buyer cannot see performance in one view. Success means 90% of priority jobs attended within four hours and a single monthly report accepted by the property team. The main delivery risk is inconsistent site access during the first eight weeks; we will own the mobilisation plan and the buyer will confirm site contacts by the contract start date.'
Supplier B is not necessarily the better supplier on every measure. But it has passed the comprehension test. The panel can now read its proposal with a clear question in mind: can it deliver what it has just promised?
What to do with the result
Use the three-sentence test before the full proposal, not after. Keep the responses alongside the evaluation record. If a supplier scores well, ask the proposal to expand the same three points rather than introduce a new narrative. If a supplier scores poorly, do not let a strong presentation team erase the gap.
The test is deliberately modest. It will not approve a supplier. It will, however, show whether the supplier can explain the job before it sells the solution. In 2026 procurement, that is a useful first filter.
