The Definition of Information Technology (IT)

- Techniques for the fast processing of information
- The "Simulation of higher-order thinking through computer programs"
- The use of statistical and mathematical models for decision-making
"While many aspects of this technology are uncertain, it seems clear that it will move into the managerial scene rapidly, with definite and far-reaching impact on managerial organization," they wrote.
Six decades later, Leavitt and Whisler were onto something big. They definite Information Technology (IT) is building communications networks for a company, safeguarding data and information, creating and administering databases, helping employees when they have trouble computers or mobile devices, doing a range of other work to ensure the efficiency and security of information systems.
