Scope creep, the uncontrolled expansion of project scope without corresponding adjustments to time, cost, and resources, remains a persistent challenge in software development projects. This study introduces a novel Scope Management Tracker Application (SMTA), a tool designed to provide real-time tracking and management of scope changes throughout the software development lifecycle. Using a mixed-methods approach, the research involved empirical evaluation through quantitative metrics and qualitative feedback from project managers and development teams. The application was tested in real-world settings, where it resulted in a 25% increase in on-time project completion and a 20% improvement in budget adherence. Additionally, the frequency of scope changes was reduced by approximately 30%, with response times shortened by an average of 48 h. Qualitative feedback emphasized the application’s user-friendly interface and its role in improving communication and transparency among stakeholders. However, suggestions for improvement included better integration with existing project management tools and the need for more comprehensive user training. Overall, the findings demonstrate that the SMTA effectively mitigates the impact of scope creep, enhances project management practices, and improves stakeholder satisfaction. Future research should explore its applicability across diverse project environments and expand its functionality to increase versatility. Continuous development and further study will be essential to unlocking the application’s full potential across various industries.
