A Modeling and Analysis Program (MAP) having a modeler, an estimator, and an evaluator is disclosed. The MAP guides the user through the design process. The modeler takes the user's input of a process diagram and creates a model organized by pages. An estimator is applied to the model to calculate the performance along the pages on each path in the model. The performance is compared to criteria. If the performance is not within a range acceptable to the user, then an evaluator is invoked. The evaluator makes recommendations for modifications to the model to improve performance.
