# Software Product Quality Evaluation

> ISO/IEC 25010 quality model (8 characteristics) + ISO/IEC 25040
> evaluation process. Structured way to say "how good is this product"
> across all quality dimensions – not just bugs.

| Field | Value |

| Product | name/version |
| Evaluator | @name |
| Context | release gate / procurement / audit |
| Date | YYYY-MM-DD |

## 1. The 25010 quality model

| Characteristic | Sub-characteristics | Weight | Target | Measured | Rating |
|----------------|---------------------|--------|--------|----------|--------|
| Functional suitability | completeness, correctness, appropriateness | | | | |
| Performance efficiency | time, resource use, capacity | | | | |
| Compatibility | co-existence, interoperability | | | | |
| Usability | operability, learnability, a11y, error protection | | | | |
| Reliability | faultlessness, availability, recoverability | | | | |
| Security | confidentiality, integrity, accountability, authenticity | | | | |
| Maintainability | modularity, testability, modifiability, analyzability | | | | |
| Portability | adaptability, installability, replaceability | | | | |

## 2. Metrics per characteristic

| Characteristic | Metrics used | Method | Data source |
|----------------|--------------|--------|-------------|
| Reliability | MTBF, defect density | operational data | monitoring |
| Performance | p95 latency, throughput | load test | benchmark |
| Usability | task completion, SUS score | user test | study |
| Security | vuln count, coverage | scan + pentest | reports |

## 3. Evaluation result

- Overall quality profile (weights applied)
- Pass/fail vs release criteria per characteristic

| Decision | Condition |
|----------|-----------|
| Accept / conditional / reject | per criteria table |

## 4. Improvement actions
