A Causal Relationship Model of Benefit Realization from Information System in Thai State Enterprise of Thailand

Abstract

Nowadays, Information Systems (ISs) are employed in for various works especially for job effectiveness. However, many organizations especially in Thai government and stage enterprises, face many problems in maximizing their ISs. This research therefore was to develop and validate a causal relationship model of benefit realization from ISs in Thai state enterprises. Data was collected from 220 respondents by paper-and-online questionnaires and 26 respondents (e.g., IT management and users)        in-depth interviews, in 8 Thai state enterprises. Descriptive analysis and the causal relationship model of benefit realization were analyzed using SPSS and LISREL, respectively; while content analysis was used to extract valuable information from interview data. The questionnaire-and-interview comparison results revealed consensus and consistency statistics. The model results demonstrated Chi-Square Test (c²) = 33.74, df = 26, Root Mean Square Error of Approximation (RMSEA) = .03, Comparative Fit Index (CFI) = .99, and Structural Equation Modeling (SRMR) = .02. All variables in the model were accounted for by 89% of the total variance in benefit realization from ISs. Consequently, in order to maximize the information technology, the model could be adopted for management planning in accordance with information technology management.
