Non-technical criteria added in the Extended ISO 9126-1 quality model

Non-technical criteria such as administrative, economical or political are often significant in software selection, sometimes even more important than technical ones.
However, these criteria have not been included in most quality models proposals. Specifically, this occurs in the case of the ISO/IEC 9126-1 standard.
We proposed some time ago a hierarchy of 141 sub-characteristics and attributes that constitute an extension of this standard. These sub-characteristics and attributes decompose 3 high-level characteristics (supplier, business, and product), each one with its corresponding metrics.
Now this quality model extension can be consulted interactively by means of QMS tool. Here you have a capture of how this quality model is consulted through QMS.
