 However, in academic literature the term "Automated Business Process Discovery" is used in a narrower sense to refer specifically to techniques that take as input an event log and produce as output a business process model.The term Process Mining is used in a broader setting to refer not only to techniques for discovering process models, but also techniques for business process conformance and performance analysis based on event logs.Process mining techniques are often used when no formal description of the process can be obtained by other approaches, or when the quality of existing documentation is questionable.
