Resources Designed to Support and Improve Information Technology (IT) Operations

What is Information Technology (IT)?

IT Departments develop, manage and maintain an organization’s technology-related assets (hardware, software, systems, etc.), policies, procedures and systems. This includes, but is not limited to, the administration of company systems, creation of system requirements that align with business needs, development of applications that meet business needs, network management, technology procurement, enforcement of technology-related policies to mitigate the risk of unauthorized access to data, data backup and retrieval, and document storage. The group also provides employees with day-to-day technology support to ensure that technology-related problems do not interfere with their work. Several industries are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce.

Org Charts

A typical information technology (IT) department is composed of several common sub-functions, or teams, that work together to define and support a company's technology-related needs. IT departments identify system requirements, develop and manage business applications, manage technology infrastructure and provide employees with desktop support, among other things. Browse our IT organization chart page to learn about the roles and responsibilities of each major function. Then, download our org chart template (PDF, Visio, PPT) to further plan and support IT operations improvement.
