## Six Quality Characteristics

- **Accuracy**: Factually correct, technically sound, current | Validation: expert review, automated testing
- **Completeness**: All necessary info present for doc type | Validation: checklist, gap analysis
- **Clarity**: Easy to understand, logical flow, appropriate level | Validation: Flesch 70-80
- **Consistency**: Uniform terminology, formatting, structure | Validation: style guide compliance
- **Correctness**: Proper grammar, spelling, punctuation | Validation: automated check, zero errors
- **Usability**: User achieves goal efficiently | Validation: task success, DIVIO type purpose served
