Enterprises did NOT experience more failures as a result of deploying more changes. High performers had less time to release changes, higher release frequency, lower time to restore service, and lower change fail rate.
Lots of interesting points about organizational culture: pathological vs. bureaucratic vs. generative (see PDF they referenced)
