created in a development context, making it difficult to apply in a service management context. But work has started to develop an ISO/IEC 20000-based process reference model (ISO/IEC 20000-4) that can serve as a basis for a process assessment model. This is planned to become part 8 to the standard (ISO/IEC 15504-8). In addition there are methods available that adapt its use to various contexts.
