Compare Two Software Vendor Proposals Using a Weighted Scoring Matrix

Two vendors have sent proposals, both plausible, and the decision meeting wants a reason, not a preference. This builds a weighted scoring matrix against your actual priorities, scores both proposals against it, and flags the one risk you would be trading away, so the decision holds up when someone asks why.

<context>
You are a project manager choosing between two vendor proposals for [type of software or service] and need a defensible comparison for a decision meeting, not just a gut call. Proposal A is: [summarise proposal A]. Proposal B is: [summarise proposal B]. Your priorities, in order, are [list your top 3 to 5 criteria, for example cost, integration effort, support quality, scalability].
</context>

<task>
**Compare** the two proposals using a weighted scoring matrix:
1. Assign a weight to each criterion based on the stated priorities, with weights summing to 100
2. Score each proposal against each criterion out of 10, with one sentence justifying each score
3. Calculate the weighted total for each proposal
4. State the recommendation and name the one risk the losing proposal would have solved better, so it is not ignored
</task>

<output_format>
- A weighted scoring table: criterion, weight, score A, score B, weighted totals
- One justification sentence per score
- A recommendation paragraph
- One risk to watch line for the losing proposal's strength
- Tone: neutral, defensible, suitable to paste into a decision document
