A scheme for performing a complex action (process), broken down into simpler operations and their relationships. Usually, this term is used to describe technologies for management of businesses, projects and document processing.

In business practice, workflow can also be used to address the flow of documents, their approval and accountability. For a comprehensive electronic management of all incoming documents (e.g. overhead invoices), one can use iNVOiCE FLOW, where the authorization workflow can be flexibly set up.
