This document specifies the tool capabilities and methods of Model-Based Systems and Software Engineering (MBSSE), including: -- The overall structure of MBSSE-specific processes and a reference model of process sets, describing how the components of this reference model are integrated; -- The interrelationships between the components of this reference model; -- MBSSE-specific processes, which are described according to their purpose, inputs, results, and tasks; -- Methods to support the tasks defined by these specific processes; -- Tool capabilities for automated or semi-automated tasks or methods. This document does not add any additional lifecycle processes for systems and software, but rather clearly defines a MBSSE reference model that is considered a set of activities. This reference model demonstrates both the lifecycle perspective of system engineering problem solving and the evolution of the system under consideration, as well as the cognitive perspective of modeling and model management. It can maintain and promote digital transformation and system and software lifecycle processes in the digital era. The processes defined in this document are applicable to individual projects and to organizations executing multiple projects. These processes are suitable for managing and executing Model-Based Systems and Software Engineering activities at any stage of the lifecycle of the system under consideration.
