IT's role is changing. As business units become ever more reliant on technology and more comfortable with implementing it themselves, IT is becoming an advisor and a service integrator rather than the direct manager of all technology assets. Forrester calls this new model "business technology" (BT). While the shift to BT is gradual, it will change the role of infrastructure and operations (I&O) professionals by adding business enablement duties to the traditional I&O focus on operational excellence.
