Visual modeling of business problems: workflow and patterns

Computer-based business analysis relies on models, or algorithmic representations of the business process. Real-life business problems can become very complex, which creates difficulties in generation, analysis, testing, and the actual use of the models. The paper discusses a proposed solution: the visual modeling workflow. A diagram or a group of diagrams represent each step within this workflow. The visual modeling process can be simplified by applying patterns or problem-solution formulas. Such modeling patterns include decoupling, encapsulation, visualization of user workflow, multilayer visual representation of the calculation logic, and early identification and visualization of uncertainties. The patterns are applied to the visual modeling workflow, which include high level conceptual modeling, using domain models and calculation diagrams to visualize the calculation logic, visualization of testing and consolidations, and visualization of results of probabilistic analysis and simulation. The described methodology is used in a number of Schlumberger´s software application.
