Document exchange is the "mother of all patterns" for business models, business processes, and business information
Business model patterns: marketplace, auction, supply chain, build to order, drop shipment, vendor managed inventory, etc.
Business process patterns: procurement, payment, shipment, etc.
Business information patterns: catalog, purchase order, invoice, etc. and the components they contain for party, time, location, measurement, etc.
These models and patterns vary in their level of abstraction and in the granularity with which they view business and it is helpful to arrange them in a single framework, which we call the "Reuse Matrix"
