Over the years, telecom operators have gone through several periods of market change; and each time the industry has evolved, carriers have been forced to reassess what is strategically important to them. This has resulted in waves of outsourcing as some carriers (but never all of them) have decided that they don't need to operate their own billing systems, or to run their IT, or their network operations centers (NOCs). In some cases, they don't need to run their own networks at all. Some have decided they can effectively compete by reselling third-party IT services; others have felt they need to be IT systems integrators with strong internal IT capabilities.
