Do we need another enterprise architecture diagram, when TOGAF already defines over 30?Process Manufacturing Reference Modeling combines value chain, functional decomposition,and ISA/Purdue reference models into one with the advantage that application scope, benefits,and integration architecture are visually mapped on to the physical business. It is not theone-diagram-fits-all solution, but could be a very useful visual metaphor for presenting complexinformation within a business context.

Process Manufacturing Core Business

To explore the applications required to support a business requires the definition of thatbusiness. The process manufacturing business is about material that is processed throughassets via a series of manufacturing events

Process Manufacturing Business

What is the core business? Is it performance, material, asset, quality, and operationsmanagement functions as defined by the standard process manufacturing models? To someextent it is, but even more fundamental to a business is what these functions are acting upon:people, material, equipment, quality, documents, finance etc. This is the ‘materiel’ assets of thebusiness. Every aspect of the business is related to managing the materiel of the business as itis processed through the assets via a series of choreographed manufacturing events:

Process Manufacturing Reference Model

The dimensions of the diagram are:

- Horizontal, the materiel dimension - Support or secondary assets such a documents, people, equipment, security, - Core competency such as intellectual property, resources - Primary assets, the material that is being process through the value/supply chain

- Vertical, the temporal dimension based on ISA/Purdue model: - Future: Plan, Schedule, Instruct, Do - Past: Measure, Check, Act, Account

Thus running through the middle of the model is a physical representation of the overallbusiness, as shown below. In this example there is a functional module that is responsible forscheduling and producing operating instructions for the ROM, Crushing, and BeneficiationPlant.

Process Manufacturing Reference Model Thus within the Process Manufacturing Reference Model we can map: - The functional scope of applications - The information and information flows - The integration benefits - Facilitate planning by identifying dependencies between applications and the mostbeneficial application areas - Map the integration to the functional architecture An example is shown below of the functional scope of applications within a mining supply chainbusiness (mine, beneficiation, refining, transportation, port, and shipping) mapped to the Process Manufacturing Reference Modelappropriate to this business.

Application Mapping to Process Manufacturing Reference Model Similarly we can map benefits opportunities within the same model. Illustrated below are thebenefits shown as a heat-map. In each area of the model the benefits are mapped to a colorscale shown to the right.

Benefits Heat Mapping to Process Manufacturing Reference Model Advantages of Process Manufacturing Reference Model

Value Chain Diagrams are useful but do not reveal the temporal characteristics as in theISA/Purdue 5-level architecture. Functional Decomposition diagrams combine the primary andsupport functions, but again do not reveal the temporal evolution of decision making. ProcessManufacturing Reference Model’sadvantage is that all information system concepts (application scope, benefits, integration) aremapped into a physical business model which happens to be the core of any processmanufacturing business. Process Manufacturing Reference Modeling is not theone-diagram-fits-all solution, but could be a very useful visual metaphor for presenting complexinformation within a business context.
