Abstract

Objectives: This research aims to find which capability of IT personnel influence on IT infrastructure capability, especially the enterprise software and the mobile application software firms doing business in Thailand. Methods/Statistical Analysis: We collected data from project managers and users of 96 participated firms by employing questionnaires which contained the constructs borrowed from the study of Fink and Neumann. Each construct was validated by Cronbach alpha coefficient. In order to reduce bias, each questionnaire required responses from 3 persons per a firm. Then the mean of responses for each questionnaire of a firm was calculated and used as the data for our research. To analyze data, we employed the stepwise regression analysis to determine which competences of IT personnel have impact on the capability of IT infrastructure. Before utilizing the stepwise regression analysis, multicollinearity must be tested: the Variance Inflation Factor (VIF) and the Condition Index (CI). Findings: Technical and business capability of Information Technology personnel affect IT infrastructure capability in the overall Thai software industry and mobile application software firms. In case of enterprise software firms, IT infrastructure capability is influenced by only business capability of IT personnel. Application/Improvements: These findings suggest that human resource policies, training and organizational development programs of these firms can be adjusted to reach the best fitting composition of personnel for the achievement of the services. In addition, universities can utilize the outputs from this study to adapt graduate programs to serve the requirements of IT providers.
