An approach for systematically and objectively assessing the health of a web site, or other complex system, using two layers of information. A scoring method is used to provide an objective qualitative judgment, together with detailed areas of analysis if desired. A set of metrics is identified, and a health score for each metric is calculated based upon assessment parameters or angles, based upon the actual data and upon the expectations. The overall health score of the system is then calculated as a composite metric based upon the individual metric health scores. A total score, together with a visual representation of the individual metric scores, is presented to the end user. The two layers of information utilized in the general framework include the domain (which determines the set of metrics and assessment parameters, e.g., web site analysis) and the model (or processing desired, e.g., a scoring model or alert model).
