One of the potential frustrations of working in a corporate IT department is the constant reminder that “IT is not our business; IT is here to serve the business.” There’s an alternative, of course: You can get a job in IT services, where information technology is the business.
Work in IT services is closely related to IT consulting (a field we covered previously), with a few key differences. Although some companies offer both IT consulting and IT services, and both types of businesses are looking to hire highly skilled IT professionals, there’s a distinct difference between the two, sources say. That difference is essentially the difference between strategy and tactics: An IT consulting firm plans new systems, while an IT services provider maintains systems after they’re deployed.
