Honoring Our Legacy, Embracing the Future

At Man-Machine Systems Assessment (MSA), we are committed to excellence, integrity, and service. Since our founding in 1990, we have built a reputation as a trusted partner in government contracting, delivering innovative solutions that support our Nation’s defense and security.

MSA was established by Cal and Martha Harris, a husband-and-wife team who combined their expertise to create a company dedicated to supporting national defense and security. With Cal’s background as a U.S. Navy servicemember and government contracting consultant and Martha’s leadership and business acumen, they built a company rooted in integrity, reliability, and mission-driven service. Martha served as CEO until 2010, guiding MSA’s growth before retiring. Today, she remains an owner and serves as an advisor, ensuring continuity and support as MSA moves forward.

Now, under the ownership of Lilly Harris, MSA is entering a new era that honors the past while embracing the future. Having grown up with the company, Lilly leads with a fresh perspective while upholding the core values that have defined MSA for decades. She is a visionary and servant leader, committed to ethical decision-making, innovation, and long-term success. Her leadership ensures that MSA remains a stable and financially strong organization dedicated to its employees, clients, and partners.

At MSA, Lilly and her team take pride in our strong client relationships, high employee retention, and reputation for excellence. We provide government agencies with the expertise they can trust, offer employees a workplace where they can grow and succeed, and give large contracting primes a reliable and capable teaming partner. Our commitment to service extends beyond contracts—it’s about making a meaningful impact through the work we do every day.

“MSA started as a dream—an idea that service, innovation, and integrity could drive real impact. Today, we remain committed to that vision by investing in the ingenuity of our people and delivering solutions that make a difference. We are not just preserving a legacy; we are building the future.”
— Lilly Harris, CEO

We invite you to be part of that future—whether as a valued client, a trusted partner, or a member of our growing team. Let’s build something great together.
