A matrix makes priorities visible. Scores need evidence and uncertainty rather than replacing measurement.
Evaluation approach
Separate security, compatibility, performance, operation and cost. Use mandatory gates that a low price cannot offset.
Application example
A product missing a required iOS extension capability may be unsuitable despite strong scores elsewhere.
Limits and considerations
Do not score uncertain marketing claims as verified test results.
Do weights predetermine the winner?
Agree priorities before scoring named products. Keep critical requirements as gates and prevent unsupported high scores from dominating the total.
Technical assessment
A decision framework to complete
No fixed set of weights suits every team. Identify unacceptable risks first, then compare candidates against the same evidence standard.
| Criterion | Evidence | Decision question |
|---|---|---|
| Required platform and framework | Tests on the final package | Are all critical components covered? |
| Enforcement | Client and server transaction records | Does the risky operation actually stop? |
| Normal use | Device matrix and support review | Is legitimate-user impact acceptable? |
| Operations | Outage and rollback exercises | Can the team manage problems safely? |
| Data management | Telemetry inventory and service terms | Are data flows necessary and manageable? |
| Cost | Volume and release scenarios | Does the estimate include non-license work? |
Do not give an unverified feature the same evidential weight as an observed result. Distinguish documented, tested and uncertain claims. A product can remain unsuitable despite a high total if it misses a critical requirement.
Checks and decisions
- Set mandatory gates
- Label evidence
- Record uncertainty
