Abstract
El siguiente trabajo de título, trata como tema central validar un modelo propuesto a partir del Modelo de Aceptación de Tecnología (TAM) que busca explicar la intención de uso de un nuevo canal de ventas por internet en la empresa farmacéutica Roche Chile, área Diagnostica.En la primera parte se presentan teóricamente los principales modelo predictores de uso de tecnologías y sus variantes, además del análisis a realizar correspondiente a un análisis confirmatorio consistente en un modelamiento con ecuaciones estructurales, SEM.En el diseño metodológico se plantea la integración de tres nuevas variables que afectan a los principales constructos del modelo de Aceptación de Tecnología (TAM) facilidad de uso y utilidad percibida, donde se plantean cinco hipótesis a comprobar. En la etapa concluyente se confecciono un cuestionario de diecisiete preguntas la cual se envió a través de correo electrónico a 156 clientes del área pública y privada.A partir de los resultados obtenidos se realizó un análisis descriptivo, que permite conocer el perfil del encuestado y un análisis factorial confirmatorio a través del modelamiento con ecuaciones estructurales utilizando el programa IBM SPSS Amos. Este procedimiento consta de ocho pasos, conceptualización del modelo, identificación del modelo, estimación de parámetros, análisis de ajuste, modificación del modelo y finalmente interpretación. En este caso se interpreta el modelo propuesto sin considerar su modificación, el cual en forma conjunta posee un ajuste de datos aceptable, solo en el caso de ajuste del modelo estructural dos relaciones no son estadísticamente significativas que corresponden a relaciones causales entre facilidad de uso sobre utilidad percibida y credibilidad sobre facilidad de uso.Finalmente se presentan las conclusiones del análisis y recomendaciones, donde se justifica el modelo planteado, aceptando cuatro de las cinco hipótesis propuestas, donde estas influyen en los principales componentes del TAM que finalmente determinarían la intención de uso de una nueva tecnología.Se plantea incorporar al análisis el modelo TAM con todas sus variables y relacionar variables externas que podrían influir en la decisión de utilización de una nueva tecnología.
The main subject of this research is to validate a model that was proposed based on the extended technology acceptance model (TAM), which aims to explain the intention to use a new internet sales channel in the pharmaceutical company Roche Chile, specifically in the diagnostics division.In the first part of the research, the main predictive models for technology use and their variants are presented theoretically, together with a confirmatory analysis that consists of a modeling with structural equations, SEM.In the methodology design, the integration of three new variables is considered. These variables affect the main constructs of the technology acceptance model (TAM); ease-of-use and perceived usefulness, where there are five hypotheses for testing. In the final stage, a questionnaire of seventeen questions was created, which was sent by email to 156 clients of the public and private sector.From the results obtained, it was made a descriptive analysis, which allows to know the profile of the respondents, together with a confirmatory factor analysis through modeling with structural equations using the program IBM SPSS Amos. This procedure consists of 8 steps; model conceptualization, model identification, parameter estimation, assessment of model fit, model modification and interpretation. In this case, the proposed model is interpreted without considering its modification, which has an acceptable data adjustment. Only in the case of structural model adjustment there are two relationships that are not statistically significant, which corresponds to causal relationships between ease-to-use of perceived usefulness and credibility of ease-to-use.Finally, the conclusions and recommendations of the analysis are presented, the model is tested and four out of the five hypotheses are accepted. These hypotheses affect the main components of TAM that would finally determine the intention to use a new technology.The idea is to add the TAM model with all its variables to the analysis and relate it to external variables that could have an influence in the decision of using a new technology.
