In an introductory talk I just gave, I discussed different views on software quality, and mentioned the Seven Signs of Successful (C++) Software Libraries, as presented in detail in the Prologue of Extended STL v1. As I was preparing the talk I realised there was no online resource that one could obtain from the name, hence this post and its searchable title (and URL).
In brief:
- Correctness, Robustness, & Reliability;
- Discoverability & Transparency;
- Efficiency;
- Expressiveness;
- Flexibility;
- Modularity;
- Portability;
Each of these is also discussed in detail in the first instalment - "Quality Matters #1: Introductions and Nomenclature" - of the column Quality Matters in ACCU's Overload journal. (Also republished with corrections here.)
