Governance refers to the implementation of operational parameters for working units and individuals’ use of IT systems, architecture, and networks. The governance of the master data is based on workflow processes that integrate business rules and subject matter domain expertise. This is part of the conventional IT security as well as the data assurance for which the IT department is also responsible.
Infrastructure refers to the hardware components, the network, the circuitry, and all other equipment necessary to make an IT system function according to the established needs and system “size” of the company.
Functionality is perhaps the most apparent task performed by the IT department. It refers to creating and maintaining operational applications; developing, securing, and storing electronic data that belongs to the organization; and assisting in the use of software and data management to all functional areas of the organization.
