Released: SysML Conversion Approach and Transition Outline
The approach and outline were developed as part of a project sponsored by the SE&A Digital Engineering, Modeling and Simulation (DEM&S).
Systems Modeling Language (SysML) Version 2 (v2) is the next generation of SysML, a standard modeling language used in systems engineering throughout industry and government. SysML v2 supports the evolving practice of model-based systems engineering (MBSE) to address challenges in increasing system complexity and rapid technology change. SysML v2 is intended to increase the effectiveness and adoption of MBSE by improving the language precision, expressiveness, regularity, and interoperability.
The paper “SysML v1 to SysML v2 Model Conversion Approach” presents a suggested approach for DoD programs to make the transition from SysML v1 to SysML v2. To illustrate the transition, the project team used a hypothetical system model, Skyzer Mission Model, developed by the https://sercuarc.org/ Systems Engineering Research Center, a DoD university-affiliated research center.
The SysML v1 to SysML v2 Transition Planning Outline and Recommendations suggests a five-step outline organizations can use and adapt as they plan the SysML transition.
19th Annual Engineers Week 2024
Wednesday, February 21, 2024, 1330 to 1500
OUSD(R&E) and Washington Headquarters Services Facilities Services Directorate co-hosted the 2024 Pentagon Engineers Week event at the Pentagon. Principal Deputy Executive Director, Systems Engineering and Architecture, Mr. Tom Simms, served as emcee. Mr. Paul McMahon, Senior Advisor to the WHS Director, and Ms. Heidi Shyu, USD(R&E)/Chief Technology Officer, provided welcome remarks.
The event included two featured speakers: Dr. Steven Walker, Vice President and Chief Technology Officer of the Lockheed Martin Corporation, and Major General Kimberly Colloton, Deputy Commanding General for Military and International Operations, Headquarters, U.S. Army Corps of Engineers.
Dr. Walker and Major General Colloton shared some of their experience as engineers, discussed the areas of technology they believe will be influential in the coming years, and offered recommendations for how current and aspiring engineers can focus their learning and experience to support their career.

Released: DoD Instruction 5000.97, “Digital Engineering”
SE&A Policy and Workforce completed and USD(R&E) approved DoD Instruction 5000.97, “Digital Engineering,” available from the Washington Headquarters Services website. Digital engineering supports the systems engineering process by moving the primary means of communicating systems information from documents to digital models and their underlying data. Digital engineering is a critical practice in an environment of dynamic threats, system complexity, and rapidly evolving technologies. The DoD instruction establishes policy, assigns responsibilities, and provides procedures for implementing digital engineering in the development and sustainment of defense systems. Specifically, the issuance directs program managers to implement digital engineering practices to maximize the benefit and to support a comprehensive systems engineering program.
Released: API Technical Guidance
SE&A released the initial Application Programming Interface Technical Guidance, providing an overview of API concepts in software development. An API defines how different software providers will share data with consumers, allowing developers to create applications that leverage the functionality of API services.
In the context of APIs, the word “application” refers to any software with a distinct function. Interface can be thought of as a contract of service between two applications. This contract defines how the two communicate with each other using requests and responses. An example is getting the weather forecast on a phone. The phone uses an API to access an external weather service to obtain a forecast. Their API documentation contains information on how developers are to structure the requests and handle responses.
The SE&A Software Engineering team collaborated with OUSD for Acquisition and Sustainment, a team from Joint All Domain Command and Control, and more than 20 DoD Components to develop the guidance.
This initial release covers governance, cybersecurity and zero trust, and API design and implementation principles. Future versions will include additional topics such as testing, DevSecOps, secure programming and error handling, performance optimization, and scalability. The guidance includes use cases, lessons learned, and best practices from DoD and industry.
The API Technical Guidance is available on the SE&A Policy and Guidance page under the heading “Software Engineering.” https://www.cto.mil/sea/pg
