Computer Selection Methodology.

The process of selecting a computer is very complex, involving much technical detail and much economic approximation. Because of the substantial investment which many organizations have in computers, it is of significant benefit to use selection procedures which minimize computer costs as much as possible within the numerous difficult constraints always present in computer selections. The issues involved in such selections are so complex, the needs and economies are so variable, and the trade-offs which must be made are so qualitative that it is not meaningful to suggest a single, universal approach to selection. Instead of attempting such a recommendation, this paper provides a framework and a basis from which the user can confidently determine a selection approach which is appropriate to his own circumstances. An exposition of the basic considerations underlying selection is presented, followed by a detailed analysis of the steps in the selection process, including alternative approaches to carrying out these steps. An account of procedures used by various organizations is given. Finally, a bibliography, organized by subject matter, is included to facilitate deeper investigation of the issues raised. An appendix contains an attempt at comparison of some major computers. [ABSTRACT FROM AUTHOR]
