A reusable starting point

A vendor decision with the evidence attached.

Use this starter to compare proposals against the same criteria and record the source for each claim. The result should show missing terms and tradeoffs before offering a recommendation.

Choose comparable criteria

Copy the prompt into a Session and add the proposal files to its Project. Replace the sample criteria with the requirements your decision maker actually uses. Mark requirements that are mandatory instead of silently weighting them all equally.

The fictional sample demonstrates the expected treatment of a missing term. It is not evidence about a real company or a recommendation for an actual purchase.

Review the table before the conclusion

Check source locations and make sure both options were judged against the same requirements. If a proposal uses a range or an assumption, keep that qualification in the table.

Ask the Agent to explain what could reverse its recommendation. Save the brief with the proposal versions used, then update the comparison when new terms arrive. A generated comparison supports your review; it does not authorize outreach or a purchasing decision.

Give the decision maker a complete packet

Keep the proposal version, currency, tax basis, contract duration, implementation fees, renewal terms, and source location beside each material claim. Compare total cost over the same period only when the inputs support that calculation. Mark absent terms as Not stated and list the question needed to resolve them.

Separate mandatory requirements from preferences. A provisional recommendation should name the unresolved term that could reverse it, the person responsible for checking it, and the decision date. This starter creates a review packet; supplier approval and any outreach remain separate actions.

Try it with a small example.

A prompt to make your own

Compare the proposals I provide using scope, delivery timing, support, and unresolved terms. Make a table with the source file and section for every material claim. Mark missing information as Not stated. Give a provisional recommendation and say what new information could change it. Do not contact vendors or approve a purchase. Save the table and brief in this Project.

Optional fictional sample: Cedar proposal says a six-week rollout and weekday support. Harbor proposal says a four-week rollout but does not state support hours. Our requirement is a rollout within six weeks and confirmed weekday support.

An illustrative result.

Fictional sample, written to show the expected structure. Your result depends on your inputs and needs review.

Fictional sample decision
Cedar: meets the stated rollout and support requirements.
Harbor: faster stated rollout; support coverage is not stated.
Provisional fit: Cedar, subject to checking the full proposal.
Next question: Ask for Harbor’s support terms before treating it as equivalent.

Before you use the result.

Every claim points to a supplied source.
Missing terms are visible instead of scored as zero.
The recommendation names its assumptions.
No vendor contact or purchase was initiated.
