Operability
How easy it is to run a system in production: deploy, debug, observe, and recover from failures.
Definition
Operability is how easy it is to run a system once it is deployed.
What good operability looks like
- You can answer “what changed” quickly, using observability.
- You can roll back safely when something goes wrong.
- Failures have a clear first step, usually captured as a runbook.
Why it matters
Designs fail in production when they are hard to operate, even if the architecture is “correct.”
