Model-based Systems Engineering (MBSE) as a methodology does not directly address capabilities, which describes the abilities of a system to achieve or perform a task or a mission. As a part of a problem description, capabilities have a strong connection to system requirements, and can be modeled using similar approaches. In the SEI Blog post Requirements in Model-based Systems Engineering (MBSE), I discussed the requirements domain. In this post, I consider the role of capabilities in system engineering—their purpose, how they are modeled and analyzed using MBSE and SysML, and how they can be associated with business requirements.
