Abstract: A method and system for validating business solutions by evaluating the business services from which the solution is composed, aggregating these evaluations in accordance with a service composition structure, and comparing the aggregated evaluation to target objectives for the business solution, where the service evaluations and the target objectives use the same metrics, which are surrogates for the business solution objectives. A business solution has a Business Level Agreement (BLA) which states business objectives. A business service has a Business Service Level Agreement (BSLA) which states operational objectives. A business solution is seen as a composition of business services. Therefore, the BLA is validated by evaluating and then aggregating the BSLA's for all business services from which the business solution is composed, and then comparing the aggregation against target values of the surrogates.
