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
