A study examined organizational culture change to determine the effectiveness of a communication based intervention program to increase productivity and motivation. The cultural change was measured through a triangulation approach combining questionnaires, interview data and direct observation. Pre- and post-intervention data were obtained in the two-year study from 243 employees of a governmental organization in the Pacific Northwest. A representative sample was interviewed and subjects completed the Organizational Culture Scale, which provides quantitative data in teamwork/conflict, supervision, involvement, climate/morale, information flow, and meetings. Additionally, subjects were directly observed in the work context. Results revealed that the organization changed significantly with regard to information flow, involvement, climate/morale, and meetings. Findings suggest that the aspects of intervention which seem to have the greatest input on culture change are communication skills training for the entire organization, involvement in decision making, and establishment of task teams. (Four tables and two figures of data are included; 47 references and three appendixes containing the organizational culture scale, operational definitions and coding decision rules are attached.)
