Abstract: | This paper presents a contingency model designed to explain aggregate differences in the specifications for production planning and control systems across firms. The specifications for a firm's system, stated broadly in terms of the investment in information processing systems and organizational integrativeness, are related to that firm's competitive strategy and environment. An analysis of data from a limited sample of companies, and a panel of managers, provides insights into the applicability of the concepts used in the model, and its potential usefulness. |
