What Happens When a Medical Office Information System Fails Andrew BEth Departmentof ComputerStudies, Universi~of Glamorgan, Pontypn'dd,Mid Glamorgan, CF37 1DL, UK. ajcblyth@glamorgan.ac.uk dlh~ IX. A s more health-care providers adopt and utilise informa tion technology in the treatment of their patients, so the number of system failures increases. Analysis of these failures shows us that these systems are failing for a variety of technical and social reason. The question that we are forced to ask is: "Why?" In this paper I seek to highlight some of the problems that are currently facing developers and users of medical computing systems. (Editor's note: this article provides additional concrete examples of the "unintentional power" discussed in Chuck Huff's article on page 6 of this issue.) Medical software incidents This failure demonstrates more than any other the fact that systems failure can be attributable to failures in the development cycle of the system. Failure to correctly capture requirements, or to validate that the requirements are met in the final system, can and does lead to system failure. The developers of the system did not correctly capture and validate the method by which the system would be used. In failing to capture and validate
