Operable Software

What does it mean to make software that doesn't just run, but is operable?

Good question! This represents some current thinking on the topic; there's tons of details in each of these things, so this list is expected to change and get more detailed over time.

Operable Software seems to involve (at a minimum) thinking a lot harder about and making sure there is a strategy (and code where appropriate) for:

Metrics
Logging
