This modification extends an existing Department of Homeland Security task order for Systems Engineering and Technical Assistance support to prevent a service gap while a recompete is finalized. The work includes expert-level program management, director support, test and evaluation mission area support, policy and workforce development, and R&D assistance. No specific budget amounts are provided. The location for performance is not specified. The extension ensures continuity until the new acquisition planning, solicitation, and award process is completed.
