Th e role of communication in public administration has been emphasized over time in public administration theory. Nonetheless, communication -with the exception of political communication -has been neglected in scholarship. Garnett's performance predicament posits the diffi culty of showing linkages between communication and performance. Th is paper explores the role that communication plays in achieving organizational performance through a review of research that bears on communication's direct and indirect infl uences on performance. Th e primary thrust is communication's indirect role in achieving performance by mediating or moderating the eff ects of organizational culture on performance, thereby adding another perspective on the cultureperformance relationship. Adapting the typology of Zammuto and Krakower, two types of organizational culture -rule-oriented culture and mission-oriented culture -are examined to explore how the relationship between organizational culture and organizational performance is infl uenced by communication. Th e analysis supports the claim that communication acts as a metamechanism for shaping and imparting culture in mission-oriented organizational cultures, thereby infl uencing performance. In particular, task orientation, feedback, and upward communication have positive eff ects on perceived organizational performance in mission-oriented organizations but potentially negative eff ects on performance in rule-oriented cultures. O ver the years, some public administration scholars and practitioners have paid attention to communication ( Downs Simon, Smithburg and Th ompson 1950 ). But for years, a mismatch has existed between the conventional wisdom that communication is the central management function most crucial to administrative success ( Barnard 1938 ; Garnett 2005 ; Lorch 1978 ) and the attention andrespect that communication has received within the public administration community in terms of scholarship and teaching. A major reason for this "respect gap" is inadequate research evidence linking communication with performance. Th is gap is partly attributable to what Garnett calls the performance predicament: "Th e costs of government communication are generally easier to measure than are its benefi ts, making it diffi cult to demonstrate a favorable performance ratio" ( 1997b , 10). Because of the diffi culty of measuring communication performance, researchers have been reluctant to tackle it head on, instead researching communication media, processes, and other aspects. At the heart of this predicament is the nature of the relationship between communication and performance. Communication's powerful, indirect infl uences on performance have remained, by and large, below the radar of public administration scholarship.Th is research more fully explores communication's indirect infl uence on performance through its eff ects on organizational culture -a variable that has been shown to infl uence performance and one that is profoundly shaped by communication. We explore whether com...
