A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, declared as work of a person or group, an organization of staff, or one or more simple or complex mechanisms. From a more abstract or higher-level perspective, workflow may be considered a view or representation of real work. The flow being described may refer to a document, service or product that is being transferred from one step to another. Workflows may be viewed as one fundamental building block to be combined with other parts of an organisation’s structure such as information technology, teams, projects and hierarchies.
