How are groups, teams, departments and divisions classified?

Processes are structured sets of activities designed to achieve a specific objective; they are workflows, not organizational units.

Functions in ITIL are defined as units of organization with defined responsibilities, resources, and capabilities that perform specific types of work. Groups, teams, departments, and divisions are all examples of organizational units and therefore classified as functions.

Roles are defined sets of responsibilities and authorities assigned to a person or team, not organizational units like departments or divisions.

Technicians is not an ITIL classification category; it is an informal job title and does not describe how organizational units are formally classified.
