Selection of computer systems to meet end-user requirements

The sequence of procedures that should be adopted are discussed. The first step is to carry out a feasibility study. This involves consultation with end-users, demonstrations, benchmark tests, and consideration of: future system upgrades, and enhancements; system obsolescence; enhancement of existing systems; software packages; and staffing. Once the feasibility study is complete and a budget approved, a detailed requirements specification can be drawn up. An invitation to tender (ITT) should then be drawn up. The elements a vendor should supply in their tender document are noted. The vendors are then shortlisted based on a technical evaluation, cost comparisons and consideration of contractual arrangements. Once an agreement has been reached with the vendor the system can be ordered, installed and acceptance tests carried out. Training and maintenance then become important
