Much literature has been devoted to singing the praises of present and potential computer utilization in marketing. Highly touted are “total information systems,” “on-line, real-time systems,” and “simulation-based systems.” One would be led to believe that each company has devoted or should be devoting its moneys and energies to the design and implementation of such sophisticated computer-based marketing information systems. Yet recent evidence has indicated a lack of enthusiasm-indeed, in some cases antagonism exists toward information systems in marketing. One reason for this disillusionment has been low usage of existing marketing information systems by marketing management. System utilization holds the key to a favorable return on investment in marketing information systems. This article explores many of the causes of infrequent to non-existent system usage and offers a plea and a plan for active elimination of this problem.
