The emergence of MSPs is a predictable macroeconomic development, says Kraft Foods Senior Vice President and CIO Steve Finnerty, a 30-year IT veteran. Companies outsource whatever is most costly to them at the time.In the 1970s, Finnerty relates, hardware was expensive. So companies engaged in hardware time-share agreements, a precursor to outsourcing.By the 1990s, software had become a huge cost center. Hence the rise of ASPs.Now, it\u2019s people that are costly. Companies can\u2019t afford to maintain huge IT staffs, which is where MSPs come in, replacing the people you\u2019d need to watch every server, router and box around the clock, making sure your applications or network don\u2019t go down."To me the [outsourcing] pendulum is following economics," Finnerty says. "That\u2019s the historical perspective I see. Moving from hardware to software to the people aspect of managing business processes."
