  • Publication number: 20070179822
    Abstract: A computer implemented method and a computer system implementing the method of a business process transformation wizard leads a business analyst through a series of steps to invoke business transformation patterns, in order to analyze the results of those processes. The wizard first prompts the business analyst to specify business objectives of process transformation. Required parameters are added to the business process model guided by the business process transformation wizard until the business process model is completed. Once the model is completed, the wizard prompts the business analyst to select transformation techniques or patterns for optimizing process parameters and, for each selected transformation pattern, optimizes process parameters using a selected optimization technique.
