What project 142 buys
The Systems Engineering project provides resources to develop and promote advanced engineering principles, techniques, and practices across the Department of War (DoW); connects and strengthens the technical community; develops the engineering and technical workforce; advances and manages standards; and provides technical expertise for independent engineering assessments to advance the development and adoption of emerging technologies with speed and agility. Engineering is the backbone of technology development and transition, playing a crucial role in turning innovative ideas into practical and real solutions. On behalf of the Under Secretary of War for Research and Engineering (USW(R&E)), this project executes the following activities: • Supports DoW’s initiatives to modernize the DoW’s systems and software engineering practices to include the use of modular open systems approaches (MOSA) and advanced systems engineering techniques to build systems capable of seamlessly incorporating new technologies to respond to emerging threats. • Furthers the adoption of digital engineering, modeling, and simulations to allow the DoW to rapidly field and implement innovative technologies for the Joint warfighter. • Furthers the adoption of modern Agile/DevSecOps (Development, Security, and Operations) software practices and improves cross-organizational collaboration to modernize DoW software processes, capability, and expertise. • Facilitates execution of the Secretary of War initiative to modernize software acquisition to acquire, deliver, and iterate on our weapon and business systems software. Supports collaboration and management activities through the DoW Software Modernization Senior Steering Group in coordination with the Office of the Under Secretary of War for Acquisition and Sustainment (OUSW(A&S)), DoW Chief Information Officer (CIO), and the Military Services. • Improves delivery of advanced capability to warfighters by modernizing reliability and maintainability, manufacturing and quality, system safety, human systems integration, and value engineering practices. • Identifies, develops, manages, and provides access to standardization processes and products for the defense community to promote interoperability, reduce cost, and sustain readiness.

What project 152 buys
The Engineering Architectures project advances efforts in system-of-systems architecture for the Department of War. The project supports the development of an enterprise-wide strategy to integrate existing and future systems to improve the Department’s technological advantage in joint, multidomain operations. Systems Engineering and Architecture (SE&A) develops policy, guidance, and training to enable rigorous engineering and the accelerated delivery of affordable, innovative, and operationally relevant mission capabilities for U.S. all-domain dominance in an environment with scarce resources, near-peer threats, and continual, rapid, and complex technological change. On behalf of the Under Secretary of War for Research and Engineering (OUSW(R&E)), this project executes the following activities: • Supports acquisition programs in the development and execution of system-of-systems engineering and architectures to enable accelerated delivery of innovative mission capabilities. • Supports the development of enterprise system-of-systems engineering architecture guidance to facilitate improved interoperability in acquisition programs. • Develops a workforce capable of fielding and sustaining enterprise system-of-systems engineering and architectures.
