How do I make a fair shortlist when products meet different parts of my requirements?

Start by separating requirements into two groups: must-haves and preferences. A must-have is a condition you consider essential; a preference is something you would like, but might trade away. Write these down before comparing candidates so you apply the same criteria to each one.

Use a matrix with one row per candidate and requirement. Include columns for candidate, requirement, importance, evidence and its source, status, trade-off, and unknown or next check. At first, label importance “must-have” or “preference” rather than assigning scores. That keeps different kinds of fit visible without implying that every requirement is interchangeable.

Record what the information actually says and where you found it, such as a product listing, packaging, or an answer from the seller. Keep the note specific: “Listing states [feature]” is clearer than “seems suitable.” If you have not checked a detail, mark it “unknown” and note what might resolve it. Do not turn a guess, assumption, or absent detail into a confirmed fact.

For example, suppose your requirements are “fits a narrow shelf” and “easy to carry,” and you are comparing two storage products. Your entries might look like this:

Candidate A | Shelf fit (must-have) | Listing gives width as [measurement] | Unknown until compared with shelf | Check shelf and product measurements Candidate A | Carrying (preference) | Listing describes [handle type] | Not enough information to judge | Check details relevant to carrying Candidate B | Shelf fit (must-have) | Width not stated | Unknown | Ask seller or find a specification

These are placeholders, not product claims. They show how to keep evidence, judgment, and follow-up separate.

First review the must-haves. Mark a known failure clearly, then decide whether that product still belongs on your shortlist. If a must-have is unknown, keep it visible rather than quietly treating it as met.

For the remaining candidates, compare trade-offs requirement by requirement. You might write, “meets [preference], but gives up [other preference]” so the compromise is explicit. If you want to use weights or scores, choose them based on what matters to you. For instance, you could decide that one preference matters twice as much as another. There is no need to use a total score: a clear comparison may be enough.

Keep the original evidence beside any score, and do not let a total conceal an unmet must-have or a major unknown. The goal is to make your priorities and compromises easier to see, not to produce an apparently objective winner.

Copy this template and add one line for each candidate and requirement:

Candidate: [name or label] Requirement: [specific must-have or preference] Importance: [must-have / preference, or your chosen weight] Evidence: [what the information says and where you found it] Status: [meets / does not meet / partly meets / unknown] Trade-off: [what you gain or give up] Next check: [question or detail to verify, if needed]

Before choosing, review known must-have failures, identify important unknowns, and compare the trade-offs that matter most to you. If two options remain close, note which preference would distinguish them and decide whether you want to rank it. The matrix organizes your reasoning, but it cannot establish facts missing from the information you have or decide which compromise you should accept.
