- Reliability – Software must be defect free and must never fail even in extreme condition. Must operate predictably and produce correct output
- Performance – Software should be able to fully exploit computing resources available to it, at the same time keeping its footprint minimal.
- Security – Best practices must be used to make system resistant against all known forms of known hacking, such as SQL injection.
- Scalability – With Cloud Computing affording global presence, software that may start out catering to the needs of just a few dozen users, may quickly need to handle millions each day, without having to be rewritten.
- Usability – Software must be easy to use and accessible through multiple devices with different screen sizes.
- Maintainability – System architecture and code must be made easy to understand and follow through standards, proper documentation, and creation of artifacts
- Portability – Software developed for one environment (hardware and/or O/S), should be able to be migrated to another with minimal rewrite of code. This principle may not be targetted, but it should be discussed and decided early on with the stakeholders
