Abstract: The invention pertains to a method and framework and tool for use in developing robust “as-is” and “to-be” cost and benefit summaries for a proposed Enterprise portal in a fast and efficient manner. The cost & benefit summaries make use of core business process data and critical workforce (per industry segment) data which are used along with cross-enterprise efficiency data to produce the Business Case summary reports. The system provides an efficient and effective way of showing the added value which an enterprise portal would bring to strategic business goals.
