In almost all organizations, IT is a support function. Workers use IT to perform business-critical functions and improve efficiency and effectiveness, but—while being critical for business operations—IT rarely is an income center for any business. In schools, this is especially true in schools, as computers are a relatively recent tool in schools, and much effective teaching and learning happens without IT. This can be demonstrated in the fact there is still resistance to using IT in teaching amongst a significant portion of educators and a reluctance amongst leaders to influence make IT decisions. If a power outage occurs on a transmission line that serves an office building and a school, it will be far more disruptive in the office than in the school. Little banking can occur in the absence of IT, but much learning can.
