Characteristics of Quality

This is a on-going work to establish what are the characteristics of quality.
 What is good software
In order to classify example projects to gain experience in our analysis, we have to know what project is to be considered as a good or bad project.

- User view: fitness for purpose.
- Manufacturing view: conformance to specifications.
- Product view: innards hidden, outside black-box works and is available.
- Value view: amount someone will pay (balance between risk and quality).
 Intuitive measures

 ISO/IEC 9126

ISO/IEC 9126 also defines 4 characteristics for the quality in use:
