Software is not just an artefact it is the artefact

Traditionally, software development
produced documents and software.
The past 15 years, this has shifted to
mostly software.

What can software tell you?
> What progress is made?
How much work is performed?
How many people are at work?
> What is the quality of the individual contributions to the system?
Is my system developed by the experienced developers I was promised?
> What is the unit test coverage?
How much demonstrably works?
> Does the implementation align with architecture concerns
Relating to, e.g., security or performance?
> What is the effort and risk associated with transitioning to production/maintenance?
