System maintenance, problems, and enhancements.
The procedures required for software and hardware maintenance of a pharmacy computer system, and methods of dealing with operational and administrative problems of such systems, are described. Maintenance of software and hardware purchased from a vendor is usually provided by the vendor under contract. Repair maintenance is required for programs that do not run, produce incorrect results, or run too slowly. Update and revision maintenance is required when user requirements exceed the limits and design of the original program. Typical problems encountered with computer systems include slow computer response time, performance of maintenance personnel, turnover in user personnel, legal liabilities and restrictions, reliability of hardware and software, downtime, security, and changing configuration of equipment. Successful management of predictable and unpredictable problems with computer systems is accomplished through systematic review of the potential problem area and prospective planning.
