Information systems analysis approach in hospitals: a national survey

A survey of 216 hospitals reveals that some hospitals do not conduct cost-benefit analyses or analyze possible adverse effects in feasibility studies. In determining and analyzing system requirements, external factors that initiate the transaction are not examined, and computer-aided software engineering (CASE) tools are seldom used. Some hospitals do not investigate the advantages and disadvantages of using in-house-developed software versus purchased software packages in the evaluation of alternatives. The survey finds that, overall, most hospitals follow the traditional systems development life cycle (SDLC) approach in analyzing information systems.
