Is there a defined list of web application quality metrics?
I'm looking for a list of metrics like performance, reliability, usability, ... with a reliable source (w3c, ...).
I want to describe how a certain technology would improve nearly all aspects of web applications. For this, I need the list of aspects from a reliable and quotable source.
All I could find was the Web Quality Model (Google Books) and ISO/IEC 9126
Am I missing a relevant source? Or is the ISO the definitive guide?
