STRATEGIC RISK MANAGEMENT TOWARDS INFORMATION TECHNOLOGY PROJECT ENVIRONMENT: AN EMPIRICAL STUDY IN THE UNITED ARAB EMIRATES (UAE)
Abstract
The strategic risk management of IT projects towards a precise definition of the role of top management has been investigated and conceptualized in this research. The study contributes to the body of knowledge in the area of strategic management in IT projects as there is a shortage of literatures in the area. The study shapes on known theories towards the formation of unknown theories which can serve as grounds for future researches in the area of strategic management of IT projects. The population of the research includes all IT professionals and senior management officials of institutions in UAE with a dedicated IT department and the sample size was determined as 384 respondents, and finally collected 371 altogether. Through a careful analysis of findings, results revealed significant and positive predictive effects of both strategic planning processes and strategic risk integration on IT project environment.
