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?
