BPM system

BPM system, noun
business process management system, noun

<enterprise> portfolio of the business processes as well as the practices and tools for governing the design, execution and evolution of this portfolio

Remark: Any process-centric enterprise has its own enterprise BPM system. The enterprise BPM system may not be perfect (e.g. some processes may be only documented on paper, some details are only “located” only in the minds of certain people, etc.), but it does exist.
