In this study, the “iron triangle,” which also covers quality management and people management, is compared to the effectiveness of an IT project. To determine the key aspects of project design that have a major impact on project success, a survey was administered to numerous project teams working in Pakistani financial institutions. Project planning, scope management, time management, cost management, quality management, and people management were some of the areas of project management that were the focus of the study. To gather data, a questionnaire was created based on the theoretical frameworks of stakeholder theory and resource dependency theory. It was discovered through observation and data analysis that the management of different IT project components has a big impact on the project's success. To further explore the management elements that were not examined in this study and the procedures that have the greatest influence on project outcomes, more research is however required. The necessity of successfully managing project components to maximize the possibility of a successful project completion is highlighted by this study, which offers useful insights for IT project managers and stakeholders.
