Harriet S.Luwemba

Harriet S. Luwemba serves as an Acquisition & Assistance Assistant at USAID/Uganda, supporting the agency’s mission to build sustainable development and institutional resilience through strategic procurement and assistance instruments. In this role, she facilitates the end-to-end acquisition lifecycle for professional services contracts, ensuring alignment with U.S. foreign assistance priorities in health systems strengthening, governance, and ecosystem management. She works closely with program officers to translate technical requirements into compliant solicitation packages, manages pre-award processes, and ensures adherence to FAR and USAID’s Automated Directives System. Her acquisitions primarily support technical assistance, monitoring and evaluation, and localized service delivery initiatives critical to advancing Uganda’s self-reliance goals. While specific contractor names are not disclosed in available records, Luwemba maintains collaborative relationships with a diverse pool of professional service providers, including international consulting firms, local Ugandan implementers, and technical experts in public health and institutional capacity building. Her procurement approach emphasizes transparency, competition, and alignment with USAID’s localization agenda, fostering partnerships that prioritize technical excellence and contextual relevance over transactional vendor relationships. Luwemba’s contracting patterns reflect a strong preference for open competition, with 85.7% of awards issued without set-aside designation. However, she actively supports small business participation through 8(a) competed contracts, which account for 14.3% of her portfolio. This balance demonstrates a commitment to broad market access while intentionally leveraging socioeconomic programs to empower disadvantaged businesses without compromising programmatic integrity. Her procurement focus is exclusively centered on NAICS 541990 — All Other Professional, Scientific, and Technical Services — encompassing a wide array of specialized support including data analysis, performance monitoring, training design, policy advisory, and technical capacity building. She consistently procures services that enhance evidence-based decision-making and institutional sustainability, particularly within PEPFAR-supported health programs and governance reform initiatives.
