I wrote the policy for our company (and got it through the audit and compliance processes, including SOX404 and PCI-DSS) that specifically and intentionally allows a specific group to take whatever action they determine is appropriate in the face of a production emergency, provided they declared the emergency, their intent, and documented/published what they did afterwards.
I believe this policy, used only a few times per year, has saved us 8 figures in outage costs over a decade. (More than half of the benefit is from a clear statement and instilled sense of ownership, and only secondarily the defusing/unraveling of people would otherwise wait or insert tangles of “best practice” red tape while the website or a factory was hard down.)
I based it on 14 CFR 91.3 (in intent) which says, in part:
91.3 Responsibility and authority of the pilot in command.
(a) The pilot in command of an aircraft is directly responsible for, and is the final authority as to, the operation of that aircraft.
(b) In an in-flight emergency requiring immediate action, the pilot in command may deviate from any rule of this part to the extent required to meet that emergency.
(I made part c of the law, the reporting requirement, mandatory where it’s only on-demand in the aviation law.)
When we explain the policy to new employees, we often cite the aviation law directly, to help clearly communicate our intent.
