This study aims to clarify the contributions of Harry P. Hatry (1930-2023), a pioneer in the field of performance measurement. To achieve this goal, it collects and examines the works he published over his 55-year career. Following a comprehensive search, 106 works were identified, of which 28 were selected for closer examination. An analysis of these works revealed general trends in the topics and sectors they addressed, as well as Hatry’s ideas and arguments regarding performance measurement. Despite some of the limitations, this study can provide valuable insights that deepen our understanding of Hatry’s arguments, which could lead to better implementation of performance measurement.
