The adoption of information and communication technologies (ICT) in public organizations promises to better connect managers with citizens, increase public participation in government decision making, improve the efficiency of service delivery, decrease uncertainty, and improve information dissemination. While each of these outcomes is important for both public managers and citizens, we know little about how organizational culture mediates the effectiveness of ICTs on producing these outcomes. This research, using data from two points in time, investigates the relationships between ICTs and managerial outcomes (e.g. improved decision making, public participation, and democratic governance) and how they are mediated by organizational culture such as centralization and routineness. Technology variables include technology use and capacity. Models will control for other organizational and technological factors such as size, structure, task and department to investigate the mediating effects of organizational culture on ICT outcomes for local governments. The data come from two national surveys of 2,500 local government managers in the United States in 2010 and 2012. The results are important for understanding the how organizational mechanisms, in particular organization culture, mobilize ICTs in ways that affect managerial outcomes.
