Process descriptions may be used either to describe generic processes (for example “project management process”) or to describe a particular instance of a generic type (for example “project management process for project A”). For specific process descriptions, generic process descriptions may be instantiated with respect to roles or responsibilities, resources, required inputs and outputs, constraints and controls, and time. Annex A provides examples of process descriptions used to develop a process model. Annex B provides a technique for demonstration of process traceability between elements, using an example process from Annex A. Processes are often combined to form a process model (framework of related processes). ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 12207, for example, provide life cycle process reference models for systems and software in which outcomes are defined and activities grouped for generic life cycle process description. Based on ISO/IEC/IEEE 15288:2015, Annex A and ISO/IEC/IEEE 12207:2017, Annex A, organizations or projects can apply process tailoring to suit the nature of the effort. NOTE 4 ISO/PAS 19450 specifies concepts, semantics, and syntax of Object-Process Methodology as a modelling paradigm and language for producing conceptual models at various extents of detail. Various schemas for characterizing and evaluating process maturity, capability or quality are in use. These schemas typically distinguish between levels of process performance and involve process improvement. Process levels can involve following the process repeatedly to successfully achieve its outcome or produce specified output, and automating and improving the process. The choice of details in the process description can be used to characterize the process description at a certain level of process maturity, capability or quality.
