NOTICE OF INTENT TO SOLE SOURCE The Department of Health and Human Services (HHS), Office of the Assistant Secretary for Health (OASH), Office on Women's Health (OWH), intends to negotiate and award a sole source follow-on contract to: Mathematica Inc. 600 Alexander Park Princeton, NJ 08540 This acquisition is being conducted pursuant to FAR 6.302-1, Only One Responsible Source and No Other Supplies or Services Will Satisfy Agency Requirements , under the authority of 41 U.S.C. § 3304(a)(1). The purpose of this acquisition is to provide continued support for the Office on Women's Health Maternal Health Portfolio, including the Interagency Coordinating Committee on the Promotion of Optimal Birth Outcomes. The contractor shall provide professional and technical support to coordinate maternal health activities across HHS, maintain and enhance the HHS Interagency Maternal-Infant Health Outcome Dashboard, develop the Annual Maternal Health Report to Congress, conduct advanced statistical analyses, prepare policy and technical reports, and provide project management and technical assistance supporting Department-wide maternal health initiatives. The Government has determined that Mathematica Inc. is the only responsible source capable of providing the required follow-on services. Mathematica designed, developed, and implemented the existing HHS Interagency Maternal-Infant Health Outcome Dashboard, including its underlying architecture, custom data models, software components, integrations, business rules, and user interface. As the developer of the existing system, Mathematica possesses unique institutional knowledge and technical expertise derived from developing and maintaining the existing dashboard, essential to maintaining and enhancing the operational dashboard while ensuring continuity of mission-critical functions. Market research conducted by the Government has not identified any alternative source capable of providing these services without substantial duplication of cost and unacceptable delays.
