Abstract: A method, system, and computer program product for determining a business level metric for assessing the impact of performance degradation of IT components upon the revenue stream of an entity is provided. In one embodiment, the business level metric is determined by determining business functions that comprises a revenue stream for a line of business. Weights are then assigned to each business function, wherein the weights indicate the relative importance of each business function in relation to the other business functions. For each business function, the business processes that enable the completion of a specific business function are determined and weights. For each business process, critical service points for measuring the performance of supporting information technology components for the business process are determined and weights are assigned. The critical service points are then monitored and a partial business level metric raw score is determined.
