“How long does it take to regress your code before moving to production?”
“How good is it?”
From “Lean Software Development” by the Poppendiecks (need to confirm):
“How long does it take you to deploy a change that involves a single line of code to production? Can you do this repeatedly and reliably?”
On every commit to source control: “How will this code be regressed next week? next month? next year?”
What's your throughput? How do you gauge taking on new work in light of that?
