The operations team is the one place with access to data and traffic that is “real-time enough” to detect business issues before they manifest in significant monetary loss. Traffic anomalies, chargeback rates, visitor retention… all these translate into money. This is what ops does; they make things work; they make the business work. And they spend a lot more time trending, investigating and analyzing than they do replacing hard drives and network cards.
