Mapeamento de requisitos em sistemas de saúde : o caso do CER-IV IMIP

Abstract

A Health Information System (HIS) has as its main function to support health care organizations from the storage and processing of information. In this context, the development process of these systems, or software in general, is complex. Failure to use appropriate methods and techniques to elicit requirements leads to costly systems, which often fail to meet the initial goal. Thus, the present dissertation makes use of Requirements Engineering to design an information system with the objective of mapping functional and non-functional requirements necessary for the construction of a HIS. For this, a Specialized Center for Rehabilitation Level IV (CER IV) of IMIP was used as a model. For elicitation of requirements, in addition to the common requirements engineering processes, the BPMN was used to map the process of patient care. The research used Design Science Research as a method of support for its development. To validate the HIS proposed here, a prototype was developed and used by the professionals of the center; later interviews were conducted with users. The results of the interview showed that the HIS is easy to use, having a great use for the process of development of CER IV activities, contributing to increase the productivity of professionals. In addition, they show that when the correct requirements elicitation techniques are applied to a given domain, such as the health area, and with the constant participation of the end user, the HIS undergoes few changes after being tested, resulting in less cost of development. From the results it was possible to propose a HIS model, composed of functional and non-functional requirements that can be used in other systems.
