Thesis, Norwegian University of Science and Technology (NTNU), Trondheim. * testing physical entities before building them (simulation), * communication with customers, * visualization (alternative presentation of information), and * reduction of complexity. OMT has proposed three main types of models: * ''Object model'': The object model represents the static and most stable phenomena in the modeled domain.(Rumbaugh et al.,1991:21) Main concepts are classes and associations with attributes and operations. Aggregation and generalization (with multiple inheritance) are predefined relationships. * ''Dynamic model'': The dynamic model represents a state/transition view on the model. Main concepts are states, transitions between states, and events to trigger transitions. Actions can be modeled as occurring within states. Generalization and aggregation (concurrency) are predefined relationships. * ''Functional model'': The functional model handles the process perspective of the model, corresponding roughly to data flow diagrams. Main concepts are process, data store, data flow, and actors. OMT is a predecessor of the

Object-oriented programming Unified Modeling Language The model is defined by the organization’s vision, mission, and values, as well as sets of boundaries for the organization—what products or services it will deliver, what customers or markets it will target, and what supply and delivery channels it will use. While the business model includes high-level strategies and tactical direction for how the organization will implement the model, it also includes the annual goals that set the specific steps the organization intends to undertake in the next year and the measures for their expected accomplishment. Each of these is likely to be part of internal documentation that is available to the internal auditor. {{uml-stub
