The standard divides quality into two primary models to capture both technical and experiential performance: Product Quality Model
: Does it perform consistently under specific conditions? Security : How well does it protect information and data? Maintainability : How easy is it to modify or update? iso iec 25010 pdf work
: Can it exchange information or perform functions while sharing environment/resources? The standard divides quality into two primary models
Based on practical reading of the PDF:
| Quality Characteristic | Target | Current | Trend | Evidence (reference to PDF section) | |------------------------|--------|---------|-------|--------------------------------------| | Functional Suitability | 100% critical functions | 98% | Stable | Clause 4.2.1.1 – Test coverage report | | Reliability | 99.9% uptime | 99.95% | Improving | Clause 4.2.4.2 – Availability metric | | Security | Zero critical vulns | 2 medium vulns | At risk | Clause 4.2.5 – Penetration test | | Usability | Task success 95% | 91% | Needs work | Clause 4.2.3.3 – User error protection | : Can it exchange information or perform functions
Define metrics for the sub-characteristics.
