Overview
Object Process Methodology is an approach to blueprint (commonly) information systems by depicting them using object models and process models.
An object model describes the integrity of an object within the analyzed system. A process model describes the flow of processes within a specific part of the analyzed system.
Objects, processes and links between them are depicted by using the object process diagram. This enables a powerful overview of the analyzed system, as the diagram features folding of components and zooming on the map of objects and processes. Having only one diagram, this methodology knows no multiplicity in depicting objects and processes, which improves exchangeability between different diagrams and even different methods.
