What does the buyer score bids on?
The contracting authority scores bids against award criteria it has announced in advance in the tender documents. These criteria and their weighting are typically made known to bidders from the start of the tender (in the United States, under the Federal Acquisition Regulation; in the United Kingdom, under the Procurement Act 2023). Scoring therefore cannot rest on anything not announced: the buyer is bound by the grid it published, and the bidder knows, before drafting, what its bid will be judged on.
This transparency rule is the anchor for the whole response: it turns scoring into a known target the technical proposal is built against.
How does evaluation proceed, from admissibility to score?
Evaluation happens in two stages: admissibility, then score. The buyer first checks that a bid is admissible, excluding those that do not meet the requirements of the tender documents, which may be treated as non-compliant, unacceptable, or inappropriate (in the United States, under the Federal Acquisition Regulation; in the United Kingdom, under the Procurement Act 2023). It then scores the admissible bids on each criterion, applies the weighting, and adds up the results into an overall score. The resulting ranking names the winning bid, and unsuccessful bidders are informed that their bid was rejected, under each market's rules.
A bid excluded at the admissibility stage is never scored: compliance with the tender documents comes before the quality of the argument.
How does weighting turn scores into a ranking?
Weighting turns scores into a ranking by giving each criterion a share of the overall score. The table links each scoring step to what the buyer does and what the bidder should take from it.
| Step | What the buyer does | What the bidder should take from it |
|---|---|---|
| Admissibility | exclude non-compliant bids | the importance of the completeness check |
| Score per criterion | judge each announced criterion | respond point by point, with evidence |
| Weighting | apply each criterion's weight | concentrate effort on the heaviest criterion |
| Overall score and ranking | add up and rank | aim for the score, not just compliance |
The consequence for the bidder is direct: since the heaviest criterion carries the most weight in the ranking, that is where the strongest evidence needs to sit.
Why does technical value come down to evidence?
Technical value comes down to evidence because the buyer scores what it can verify, not what is merely asserted. A method described with its resources, its controls, and its references scores better than a general promise, because the evaluator finds material there to justify the score. Precise terminology drawn from the technical specification, which describes the requirement, helps the evaluator connect the response to the requirement.
A proposal that asserts without proving leaves the evaluator nothing to score highly; a proposal that proves gives the evaluator the material for the best score.
When is reading the criteria enough, and when do you need a detailed analysis?
For a simple contract, reading the criteria and their weight is enough to guide the response. For a contract with a dense set of requirements or detailed sub-criteria, a detailed analysis of the grid becomes useful: it links every sub-criterion to a piece of evidence, so no points are left on the table. Generic AI can summarize a criteria grid; systematically matching requirements to the company's evidence is compliance work. The line is the granularity of the grid and what is at stake in the score.
On the Optivalue.ai platform, which publishes this site, every response gets a confidence score from 0 to 100 and cites its source, which helps allocate the evidence effort according to the weight of each criterion.
Mistakes that cost points in scoring
- Neglecting admissibility: a non-compliant bid is excluded before it is scored, whatever its quality.
- Responding evenly across the board: ignoring the weighting scatters effort away from the criterion that counts.
- Asserting without proof: the evaluator scores what it can verify, not promises.
- Ignoring the sub-criteria: a detailed grid rewards responses that address every sub-criterion.
- Writing for yourself, not the evaluator: a response that does not mirror the criteria forces the buyer to hunt for its points.
Frequently asked questions
Is price always a scoring criterion?
Price or cost is very often a criterion, alongside technical value and other criteria. Its weighting appears, like the others, in the tender documents announced in advance.
Can the buyer change the criteria along the way?
No. The criteria and their weighting are announced from the start of the tender and bind the buyer. Scoring is done against that published grid, not against anything added later.
Can you find out the score of the winning bid?
An unsuccessful bidder can obtain the characteristics and advantages of the winning bid, subject to the protection of trade secrets, under each market's rules. This lets you measure the gap to close.
Does this scoring logic apply outside France?
The principle of announced, weighted criteria is widespread; the specific rules differ by market. Each market follows the law of its own jurisdiction (in the United States, the Federal Acquisition Regulation; in the United Kingdom, the Procurement Act 2023).
