A prediction-enabled component technology (PECT) is an infrastructure that supports predictable assembly from certifiable components. An assembly process is predictable if the runtime properties of an assembly of components can be predicted from the properties of its components. Components are certifiable if their properties can be obtained, or validated, by disinterested third parties. Structurally, a PECT supports a central constructive view in a 'component and connector' descriptive style. One or more analysis views are formally linked to this central view by means of interpretations. Each analysis view supports some form of compositional reasoning about assembly properties; each interpretation may impose constraints on the constructive view. This talk describes a core (constructive) component technology for PECT, and gives an overview of the key development activities for developing and validating analysis views and their interpretations. The main ideas are illustrated using prototypes jointly developed by the SEI, ABB, and Mälardalen University.
