This guide discusses three critical steps in selecting microcomputer software and hardware: setting the context, software evaluation, and managing microcomputer use. Specific topics addressed include: (1) conducting an informal task analysis to determine how the potential user's time is spent; (2) identifying tasks amenable to computerization and matching them with existing programs; (3) hardware options; (4) screening of software; (5) sources for software evaluations; (6) criteria for software evaluation, e.g., ease-of-use (set-up, installation, initial learning, and use after initial learning), program performance (speed, error handling, and versatility), and support (printed documentation, on-screen documentation, and supplier/manufacturer); (7) software selection; and (8) services, training, and facilities necessary to manage computer use. Appendices include a software evaluation summary form and a software evaluation worksheet, which provide suggestions for rating software on the specific components of the major evaluation criteria specified in the guide. Three references are listed. (JB)
