The Ultimate Purpose of Software is to help somebody achieve a greater goal 1. The degree of Software Goodness of a piece of software is the degree to which the software realizes its ultimate purpose.
For example, software that helps 1M people learn algebra can be said to have greater Software Goodness 2 than another software that helps only 100 people learn algebra.
Note that people who benefit from software can be anyone impacted by the software, other software engineers, for example. If a library is a joy to use (due to its -ilities [readability, simplicity, robustness, etc]), then it can be said that it achieves greater Software Goodness than a library that is a pain to use (due to its lack of -ilities).
What drives a person to pursue Software Goodness?
That is why an engineer writes Better Software when she works for a company whose goal she Cares about. However, a Care for other software engineers (and her future self) will also increase her motivation to produce software with a high degree of internal quality (the -ilities [maintainability, readability, extensibility, etc]).
