Business process interoperability (BPI) is a property referring to the ability of diverse business processes to work together, to so called 'inter-operate'. It is a state that exists when a business process can meet a specific objective automatically utilizing essential human labor only. Typically, BPI is present when a process conforms to standards that enable it to achieve its objective regardless of ownership, location, make, version or design of the computer systems used.

It is a state that exists when a business process can meet a specific objective automatically utilizing essential human labor only. Typically, BPI is present when a process conforms to standards that enable it to achieve its objective regardless of ownership, location, make, version or design of the computer systems used. The main attraction of BPI is that a business process can start and finish at any point worldwide regardless of the types of hardware and software required to automate it. Because of its capacity to offload human 'mind' labor, BPI is considered by many as the final stage in the evolution of business computing. BPI's twin criteria of specific objective and essential human labor are both subjective.
