Selection and evaluation of software

Two aspects of the selection and evaluation of software packages are reviewed: the strategy for evaluation and selection, and criteria that might be applied in selection. The evaluation and selection of a software package should be approached as a project. Appropriate strategies for the selection and evaluation of software packages can be based on information systems methodologies. The main stages in the project are: definition of objectives, evaluation of options, definition, selection and design, implementation and evaluation and maintenance. A system requirements specification is an important document in this process. Software selection must be guided by appropriate criteria. General criteria are cost, lifetime and life history, originator, supplier, support, maintenance, technical considerations and compatibility, ease of use, interfaces and integration. In addition specific criteria must be developed for specific categories of packages. A checklist of criteria for database packages is given.
