- Mainly qualitative criteria (errors, different
evaluation)
- Generalised criteria (they have to be weighted
according to site characteristics)
- Non
orthogonal criteria (same characteristics accounted more
than once)
- Criteria are essentially accessibility or
usability biased
- Granularity (page or site)
- External vs internal quality
- A rigorous approach requires that characteristis are
measurable:
