摘要:The purpose of this paper is to explore the critical success factor for implementing standards, best practices and codes of ethics, what their benefits are when implemented and how they impact the quality of information technology (IT) services. Through extensive literature review and interview with experts in the field we identified instrumental determinants. The structural equation model (SEM) has been used on the case of IT departments in large Slovenian companies to test the hypotheses presented. The study is based on 102 responses from IT managers in large Slovenian companies. Research findings confirmed a positive correlation between used factors. DOI: 10.15458/85451.39
