System and method for improving predictive modeling of an information system

A computer-implemented method for improving the accuracy of a predictive model of a proposed information system, the information system including system architecture, one or more software applications, system hardware and networking components, the method comprising:

• (a) generating a predictive model of the proposed information system comprising a business layer, an application layer, and a system layer, each layer modeling dynamic characteristics and behavior of one or more components;
• (b) calculating individual performance metrics for each component modeled in the application and system layers from the dynamic characteristics and behavior;
• (c) comparing the calculated individual performance metrics against predefined individual performance benchmarks to assess the accuracy of the predictive model;
• and
• (d) performing a sensitivity analysis on individual component models that do not substantially match a corresponding performance benchmark, said performing a sensitivity analysis providing assessment of accuracy of the predictive model in a manner enabling improvement of accuracy of the predictive model.
