Leaders of nonprofit organizations in the United States must build workforce capabilities to meet increasing demands for services. This single-case study explored strategies nonprofit leaders used to build workforce capability to address increasing service demands. The conceptual lens for this study was the full-range leadership theory. Data were collected through semi-structured interviews with senior executives of a single nonprofit organization located in the Midwestern region of the United States, which included internal organizational and workforce performance data, strategy plans, annual reports internal and external financial documents, and publicly available information. Four major themes related to building workforce capacity emerged from a thematic analysis of the data: (1) an emphasis on employee development, (2) the expansion of technology systems, (3) a concentration on developing a culture of autonomy and trust, and (4) the introduction of processes and measurements. The findings from this study might contribute to positive social change by providing nonprofit leaders with strategies and data to support a deeper understanding of how to effectively build workforce capability to address increasing service demands.
