ABSTRACT
El objetivo del presente trabajo es analizar la herramienta de decisión TEMIX, especializada en la evaluación de tecnologías de información sobre la base de criterios de negocio, para la clasificación de la organización que se realiza durante el diagnóstico de planificación de sistemas de información, con la finalidad de facilitar la determinación de objetivos de integración de información relevantes atendiendo al nivel de coordinación que requiere el desempeño del negocio analizado. Como métodos se emplearon casos de estudio, diseño de cuestionarios, modelación mediante predicados compuestos y lógica difusa compensatoria. Como resultado del empleo de TEMIX, además de la evaluación de tecnologías de información basada en las características del negocio, se obtuvo la documentación sobre los requerimientos de integración de la cadena de suministro y de la empresa.
The main goal of this paper is to review the use of a decision tool, named TEMIX, during the diagnosis needed in the Information Systems Planning Process, to ease the assessment of business requirements that are relevant to express the coordination level required by the business performance. The methods used were: case studies, questionnaire design, compound predicates modeling and compensatory fuzzy logic as decision theory. TEMIX use results in information technology assessment based on business needs and on supply chain and business information integration requirements analysis.

Como métodos foram empregues casos de estudo, desenho de inquéritos, modelação mediante predicados compostos e lógica difusa compensatória. Como resultado do emprego de TEMIX, para além da avaliação de tecnologias de informação baseada nas características do negócio, foi obtida a documentação sobre os requerimentos de integração da cadeia de fornecimento e da empresa.

CONTEXT: Permanent evaluation of end-user satisfaction and continuance intention is a critical issue at each phase of a clinical information system (CIS) project, but most validation studies are concerned with the pre- or early post-adoption phases. OBJECTIVE: The purpose of this study was twofold: to validate at the Pompidou University Hospital (HEGP) an information technology late post-adoption model built from four validated models and to propose a unified metamodel of evaluation that could be adapted to each context or deployment phase of a CIS project. METHODS: Five dimensions, i.e., CIS quality (CISQ), perceived usefulness (PU), confirmation of expectations (CE), user satisfaction (SAT), and continuance intention (CI) were selected to constitute the CI evaluation model. The validity of the model was tested using the combined answers to four surveys performed between 2011 and 2015, i.e., more than ten years after the opening of HEGP in July 2000. Structural equation modeling was used to test the eight model-associated hypotheses. RESULTS: The multi-professional study group of 571 responders consisted of 158 doctors, 282 nurses, and 131 secretaries. The evaluation model accounted for 84% of variance of satisfaction and 53% of CI variance for the period 2011-2015 and for 92% and 69% for the period 2014-2015. In very late post adoption, CISQ appears to be the major determinant of satisfaction and CI. Combining the results obtained at various phases of CIS deployment, a Unified Model of Information System Continuance (UMISC) is proposed. CONCLUSION: In a meaningful CIS use situation at HEGP, this study confirms the importance of CISQ in explaining satisfaction and CI. The proposed UMISC model that can be adapted to each phase of CIS deployment could facilitate the necessary efforts of permanent CIS acceptance and continuance evaluation.
