What We Do

The SEI's mission is to support the nation’s defense by advancing the science, technologies, and practices needed to acquire, develop, operate, and sustain software systems that are innovative, affordable, trustworthy, and enduring.

Our Process

Our work process is designed to be highly iterative, enabling any design or innovation to be tested early and tested often. We can apply lessons learned in any given development phase by returning to any earlier development phase at any time, instantly realizing improvements to the state of the practice.

The Software Engineering Institute work process, including research, prototype, mission application, and training & education


We research software and cybersecurity problems of considerable complexity. We apply first principles of relevant information science, computer science, and mathematics to mature the disciplines of engineering and secure software systems.
