We present a conceptual framework for business process modelling of a wide range of enterprises, based on business functions and processes. A super-collection of functions and processes - a “metamodel” - has been compiled, based on 101 industrial organizations. Its two levels comprise a “capstone” model, detailing major functions and their breakdown into main functions; and a series of “functional decomposition” models, one for each major function, detailing the business processes associated with each main function. The end result encompasses 29 major functions, 169 main functions and over 2,000 business processes. In order to build an enterprise model, the designer has primarily to decide which major functions are needed; the related main functions and processes are a consequence of this decision.
Major functions comprise two key groups: business functions (policymaking, economics, finance, commerce - buying and selling, human relations and administration); and industrial functions (production of goods or provision of services). These are further sub-divided into five classes: basic business, business support, production, production support and service provision. We find that all the enterprises surveyed have implemented almost all the basic business functions, being differentiated by their implementation (or non-implementation) of the industrial functions.
We detail a set of “business function model applications”: model construction and refinement; comparison of an enterprise model with a vendor model, another enterprise model or an industry standard or leader; and use of the model for business process engineering and re-engineering, integration and communication along the supply chain, and as a guide to process-oriented management style.
