The system they are using (IC, ops, engineer teams, operational periods) is extremely similar to the Incident Command System. The ICS was developed about 40 years ago for fighting wildfires, but now most government agencies use it to manage any type of incident.
I've experienced it first hand and can say it works very well, but I have never seen it used in this context. The great thing about it is it's expandability---it will work for teams of nearly any size. I'd be interested in seeing if any other technology companies/backend teams are using it.
