Applications have moved outside the IT department. There’s a truism that all companies are now software companies, and the ability to rapidly provide new services and new functionality to customers is one of the key competitive differentiators a company can offer. IT agility is a stone that startup Davids can use to unseat massive Goliaths. Once upon a time, several generations ago (in technology years), IT departments were internal departments, focused on maintaining infrastructure and services within the company. Some companies may have had external-facing services, particularly web services, but this was still generally a narrow and restricted area. IT wasn’t a revenue-generating or strategic department; it was a supporting environment viewed as a cost center.
