Model-based systems engineering (MBSE) is a formalized methodology that supports the requirements, design, analysis, verification, and validation associated with the development of complex systems. MBSE in a digital-modeling environment provides advantages that document-based systems engineering cannot provide. These advantages have led to increased and growing adoption since MBSE can save costs by reducing development time and improve the ability to produce secure and correctly functioning software. The SEI CERT Division has begun researching how MBSE...

Model-based systems engineering (MBSE) is a formalized methodology that is used to support the requirements, design, analysis, verification, and validation associated with the development of complex systems. In contrast to document-centric engineering, MBSE puts models at the center of system design. The increased adoption of digital-modeling environments during the past few years has led to increased adoption of MBSE. In January 2020, NASA noted this trend by reporting that MBSE, "has been increasingly embraced by...

Julia Scherb coauthored this blog post. The Department of Defense's desire for faster delivery of new capabilities is transforming defense acquisitions. The emerging processes of digital thread and digital engineering aim to address the difficulties of managing complex and evolving technologies over their lifecycles. In the same way that DevSecOps has transformed the processes of software development, testing, and acquisition for the DoD, digital engineering has the potential to transform the way hardware-intensive systems are...
