“Our highest priority is to satisfy the
customer through early and continuous
delivery of valuable software.”
“Deliver working software
frequently, from a couple of weeks to
a couple of months, with a preference
to the shorter timescale.”

“THING RIGHT”

“How long would it take your organization to
deploy a change that involves just one
single line of code? Do you do this on a
repeatable, reliable basis?”
