Several researchers have conducted empirical studies using numerous factors (e.g. organizational, technological, and individual factors) which affect the information system success. However, there are several factors which are related to interpersonal conflict which may affect information system success. The interpersonal conflict is a critical dimension which can greatly influence information system success in a competitive environment such as the financial sector. Therefore, this study introduces a framework to investigate the influence of interpersonal conflict factors on information system success in the Ministry of Finance, Yemen. The study employed a quantitative method which consists of the following steps: survey design, data collection and data analysis. A sample size comprising 130 employees were distributed in the Ministry of Finance, Yemen. Questionnaires were used to collect data from this sample. Data analysis (reliability, validity, correlation and factor analysis) has been carried out using SPSS. In addition, structural equation modelling (SEM) has been used for evaluation the research model. Based on the experimental results, the findings in this study revealed that the interpersonal factors (interference, disagreement and instability) significantly negatively (at 0.05 level of significance) influence user satisfaction of information system success.

INTRODUCTION Information system (IS) is one of the important points which lead to the success of an organization, especially an organization that requires management and financial processing [1]. The success of the information system is also important not only for organizations to improve their efficiency and productivity, but also for developers who are responsible for enhancing and improving the systems. Therefore, the main challenge is how to assess the information system success based on user perception. Previous studies have investigated the factors that can be used to measure the IS success based on the users’ perception [2]-[5]. Most of the prior researches in the field of IS success have focused mainly on information quality, system quality, service quality, perceived usefulness, user satisfaction, user perception, and also organizational and technological factors [3], [6], [7]. Other researches consider interpersonal conflict [8]-[10] factors as important predictors of the success in the information system development. However, limited number of studies have been conducted to examine the effects of these factors on IS success.
