Model‐Based Systems Engineering (MBSE) is gaining popularity in organizations creating complex systems where it is crucial to collaborate in a multi‐disciplinary environment. SysML, being one of the key MBSE components, has a good foundation for capturing requirements, architecture, constraints, views and viewpoints. It allows linking different types of models that come from different engineering disciplines. However, inherent safety and reliability aspects of a system are not addressed by the SysML language. A new group at the OMG has been created by industry experts in this area to address these aspects in a new standard. In this paper, with the intent to get feedback from the systems engineering community, the members of the newly formed group present the current state of the Safety and Reliability Analysis Profile for UML submission, which extends the SysML language with the tools for modelling safety and reliability aspects. This paper also explains the value users get from taking a model‐based approach to safety and reliability analysis and integrating it into the MBSE toolkit. Open issues and challenges are also discussed.
