The present invention extends to methods, systems, and computer program products for linking service level expectations to performing entities. Embodiments of the invention facilitate an express, measured relationship between each entity and the performance of a corresponding business capability. Thus, when an entity or layer changes, the impact to the performance can be asserted, and later validated through the specific measures. Schematized links for entities and/or business layers can be used to connect to a service level expectation schema to appropriately define how entities and/or business layers contribute to the performance of a business capability.
