SETA stands for Systems Engineering and Technical Assistance. It refers to government contractors who are contracted to assist the United States Department of Defense (DoD) components and acquisition programs. SETA contractors provide analysis and engineering services in a consulting capacity, working closely with the governments own engineering staff members. They provide the flexibility and quick availability of expertise without the expense and commitment of sustaining the staff long-term. SETA efforts are generally long-term contracts that provide anything from project management and technical expertise to administrative and computer support. SETA contractors are civilian experts who provide analysis and engineering services to the government and often work hand in hand with government engineering staff. They serve as subject matter experts, working side-by-side with their government counterparts to better meet evolving needs and demands.
