Citing the growing interest in using microcomputers as an aid in educational administration, this report discusses factors that must be considered when purchasing a computer and describes an actual case of computer implementation for administrative purposes. The first steps in the purchasing process are to assess and to prioritize the administrative uses for the computer, to ensure purchase of an effective system, and to regulate its implementation. Costs to be considered when selecting a system include not only those for hardware and software, but also those for training the staff, obtaining incidental equipment, maintaining service contracts, and providing suitable operating space. The potential utility of the system must be weighed against any obstacles to easy implementation of the system, including possible staff resistance. Software selection should involve evaluation of alternative programs and of the expert support available. Inservice training programs aimed at developing specific staff skills should be planned carefully. Finally, an evaluation plan incorporating needs assessment, formative evaluation, and product evaluation should be included in the purchasing process. The Atlanta (Georgia) South Metro Psychoeducational Center considered the above factors in designing a successful six-phase development and installation plan for its data management system. (PGD)
