Information technology operations

Information technology operations, or IT operations, are the set of all processes and services that are both provisioned by an IT staff to their internal or external clients and used by themselves, to run themselves as a business. The term refers to the application of operations management to a business's technology needs.[1] The definition of IT operations differ throughout the IT industry, where vendors and individual organizations often create their own custom definitions of such processes and services for the purpose of marketing their own products. Operations work can include responding to tickets generated for maintenance work or customer issues.[2] Teams can use event monitoring to detect incidents.[3] Many operations teams rely on on-call responses to incidents during off-hours periods.[2] IT operations teams also conduct software deployments and maintenance operations.
