Meta-análisis sobre la implantación de sistemas de planificación de recursos empresariales (ERP)

The study presents a systematic literature review on the implementation of ERP systems. The analyses are based on 168 articles published in ISI journals. Firstly, the course of investigation on the phenomenon is investigated. Then, methodologies under use are specified in the analysis: field work - statistical technique and variables; case studies - the type of design and study problem; conceptual works - their impact on literature. Additionally, critical success factors proposed for the implementation of ERP systems are summarized. Lastly, with the purpose of supporting the development of future assumptions, some conclusions are provided on the scientific background for the study. A general analysis concludes that publications on ERP system implementation show a clear expansion trend, and are concentrated in information system journals. Empirical studies are privileged, with case studies used more frequently. Organizations under study are usually multinationals in the industrial sector. Based on that review, one concludes that: 1- organization size plays a key role in ERP systems implementation; 2- the factors that affect late ERP adoption differ from those that affect early implementation; 3- cultural collision can be felt at ERP implementation; 4- diligent studies on success factors in ERP implementation are few in number; 5- there is not one single dimension to measure ERP system success.Este estudio expone una revisión sistemática de la literatura científica sobre la implantación de sistemas ERP. Tomando como punto de partida 168 artículos publicados en revistas científicas ISI se realizan un conjunto de análisis. Primero, se estudia la evolución de la investigación sobre el fenómeno. Luego se particulariza según las metodologías de investigación empleadas, este análisis incluye: en los trabajos de campo, las técnicas estadísticas utilizadas y las variables estudiadas; en los estudios de casos, el tipo de diseño y el problema de estudio; y en los trabajos conceptuales su impacto en la literatura. Adicionalmente, se sintetizan los factores críticos de éxito propuestos para la implantación de sistemas ERP. En último lugar, y con el objeto de dar soporte al desarrollo de hipótesis futuras, se entregan algunas conclusiones sobre los antecedentes científicos recogidos en el estudio. En un análisis general, se concluye que las publicaciones sobre implantación de sistema ERP presentan una clara tendencia de crecimiento y se concentran en revistas de sistemas de información. Los estudios empíricos son preferidos, el estudio de caso es utilizado con mayor frecuencia, y normalmente las organizaciones estudiadas son grandes multinacionales del sector industrial. Por otra parte, a partir de la revisión de los trabajos se concluye que, primero, el tamaño de la organización juega un rol importante en la implantación de sistemas ERP. Segundo, los factores que afectan la tardía adopción de un ERP difieren de aquellos que afectan su adopción temprana. Tercero, en la implantación del ERP existe una colisión cultural. Cuarto, existen pocos estudios científicos rigurosos sobre factores de éxito de la implantación de ERP. Y quinto, no existe una sola dimensión para la medición del éxito del sistema ERP

eWOM & Referrals in Social Network Services

If a few decades ago the development of the Internet was instrumental in the interconnection between markets, nowadays the services provided by Web 2.0, such as social network sites (SNS) are the cutting edge. A proof of this trend is the exponential growth of social network users. The main objective of this work is to explore the mechanisms that promote the transmission and reception (WOM and referrals) of online opinions, in the context of the SNS, by buyers of travel services. The research includes some research lines: technology acceptance model (TAM), Social Identification Theory and Word-of-Mouth communication in virtual environment (eWOM). Based on these theories an explicative model has been proposed applying SEM analysis to a sample of SNS users’ of tourist service buyers. The results support the majority of the hypotheses and some relevant practical and theoretical implications have been pointed out for tourist managers

E-Learning and gender

This study is to examine gender differences and the adoption of technology in tertial education students. We have used TAM model to measure the acceptance and use of elearning of the respondents. ANOVA and Partial Least Squares (PLS) was used, specifically, the PLS multi-group analysis, to compare differences between groups. In summary, results show that students’ behavior of acceptance of e-learning technology do not manifest statistically significant differences between women and men

El Nivel de la Inversión en Tecnología de Información No Afecta el Rendimiento Empresarial: Evidencia Empírica de las Industrias Manufactureras Chilenas

Con el propósito general de evaluar el impacto de la tecnologías de información (TI) en el rendimiento industrial dentro del contexto de un país en desarrollo, y basado en una muestra de 212 grandes empresas manufactureras chilenas, este estudio tiene por objetivo medir la influencia de la inversión en TI sobre la eficiencia relativa de las organizaciones. Para lograr este objetivo, se ha construido una medida multidimensional de eficiencia relativa basada en el análisis envolvente de datos (AED). Luego se han aplicado test ANOVA para evaluar, por una parte, si la inversión en computadores, y por otra, si la existencia de software empresarial, diferencian significativamente la eficiencia relativa de estas organizaciones. Los resultados del estudio indican que no existen diferencias estadísticamente significativas entre la eficiencia relativa de estas empresas manufactureras de la muestra y su nivel de inversión en TI

Purchase intention of specialty coffee

The main aims of this study are: (1) to test whether the theory of planned behavior (TPB) is useful to explain the intention to purchase specialty co ee; (2) to analyze whether people more involved in social responsibility could manifest a di erent response from those not so interested in this matter concerning specialty co ee. The sample is composed of 489 specialty co ee consumers from Brazil. The statistical tool for testing the measurement and structural model was partial least squares. Then a multigroup analysis was performed to meet the second objective; the software SmartPLS was utilized. The main contributions of this study are that we can explain the intention to use specialty coffee in a sample of Brazilian consumers using the classical TPB model. Moreover, we demonstrate the moderating e ect of consumer perception of corporate social responsibility in this general model

Towards to personal profiles of online video game players: application of POS-PLS on UTAUT model

There are diverse segmentations of online players in the literature. Most of them are proposed a priori, and there are no segmentations based on the acceptance of technology and the personal values of the players. The foremost purpose of this study is to obtain a clustering of online video games players, founded on UTAUT model, and to describe the subsequent segments consistent with the personal values of Schwartz. The measurement model and the structural model was analyzed with partial least squares (PLS). Subsequently, the POS-PLS technique has been devoted to inspect unobserved heterogeneity and to find players’ segments. Four segments are obtained from the statistical tools

Exploration of the factors that affect the adoption of social networking services by generation y in Chile

The purpose of this paper is to study the adoption of social networking services (SNS) for a sample of members belonging to the Generation Y in Chile. The study used an adapted technology acceptance model (TAM) to measure the acceptance and use of SNS of the 173 respondents (111 women and 62 men). The basic TAM was enhanced with three antecedents of perceived usefulness: social identity, telepresence and altruism. Structural equation modeling has been applied to test the proposed model. Results show that a version of TAM model explains the adoption of SNS by Generation Y in Chile.El propósito de este trabajo es estudiar la adopción de los servicios de redes sociales (SRS) en una muestra de miembros pertenecientes a la Generación Y en Chile. El estudio utilizó una adaptación del modelo de aceptación de tecnología (TAM) para medir la aceptación y el uso de los SRS en 173 encuestados (111 mujeres y 62 hombres). El modelo TAM básico fue en riquecido con tres antecedentes de la utilidad percibida: identidad social, telepresencia, y altruismo. La técnica de modelado de ecuaciones estructurales se utilizo para probar el modelo propuesto. Los resultados muestran que la versión del modelo TAM explica la adopción de la SRS por la Generación Y en Chile.O propósito deste trabalho é estudar a adoção dos serviços de redes sociais (SRS) em uma amostra de membros pertencentes à Geração Y no Chile.

Telemedicine acceptance during the Covid-19 pandemic : an empirical example of robust consistent partial least squares path modeling

The explanation of behaviors concerning telemedicine acceptance is an evolving area of study. This topic is currently more critical than ever, given that the COVID-19 pandemic is making resources scarcer within the health industry. The objective of this study is to determine which model, the Theory of Planned Behavior or the Technology Acceptance Model, provides greater explanatory power for the adoption of telemedicine addressing outlier-associated bias. We carried out an online survey of patients. The data obtained through the survey were analyzed using both consistent partial least squares path modeling (PLSc) and robust PLSc. The latter used a robust estimator designed for elliptically symmetric unimodal distribution. Both estimation techniques led to similar results, without inconsistencies in interpretation. In short, the results indicate that the Theory of Planned Behavior Model provides a significant explanatory power. Furthermore, the findings show that attitude has the most substantial direct effect on behavioral intention to use telemedicine systems
