Computer Aided Management Decision Making:A Practical and Theoretical Study

Abstract

The present research attempted to study some of the problems of achieving successful implementation of new computer-based system designs. In particular it considered the implementation of management information systems having a limited number of users. An examination of the literature led to the conclusion that an important requirement for successful implementation was that the expectations of the ultimate user should be taken into account. Initially the research was delayed because of the lack of existing techniques that could adequately reveal such expectations and so enable them to be incorporated into the design process. After some time however, the technique of repertory grid testing, which is based upon personal construct theory, was discovered. This test was originally devised for use in psychotherapy but in the present study a test form was developed that was suitable for investigating managers' expectations. A preferred method of analysis was also developed. In order that implementation could be studied in a realistic way, the research was carried out in a sponsoring Company for whom a small computer-based management information system was developed and implemented. The final form of the repertory grid test was used upon the managers who would finally use the management information system and it was found to be efficient in revealing their attitudes to, and expectations of, computer systems in the context of their own jobs. More detailed investigation and development of the test was curtailed (a) by the considerable time requirements associated with developing a worthwhile and practical computer-based management information system having utility for its intended user(s) and (b) by the considerable changes that took place during the research period in both the Company's products with which the management information system was concerned, and in the managers associated with the system.
