Adaptability is a property related to engineering as well as to the execution of networked service systems. This publication considers issues of adaptability both within a general and a scoped view. The general view considers issues of adaptation at two levels: system of entities, functions and adaptability types, and architectures supporting adaptability. Adaptability types defined are capability-related, functionality-related and context-related adaptation. The scoped view of the publication is focusing on capability-related adaptation. A dynamic goal-based policy ontology is presented. The adaptation functionality is realized by the combination of extended finite state machines, reasoning machines and learning mechanisms. An example case demonstrating the use of a dynamic goal-based policy is presented.
