A Comparative Analysis of Agile and Traditional Project Management Methodologies: Impact on Project Success Metrics in the IT Sector Amid Rapid Technological Evolution

Abstract

This study investigates the impact of agile and traditional project management methodologies on project success in the IT sector, where dynamic requirements and rapid technological changes are expected. Traditional methodologies, like the Waterfall model, follow a linear process suited for well-defined projects but struggle with adaptability. In contrast, agile methodologies prioritise flexibility and stakeholder collaboration, enabling quicker delivery. Employing a qualitative research design, the study involved semi-structured interviews and case studies with IT professionals and project managers experienced in both methodologies. Thematic analysis revealed that agile approaches achieve higher stakeholder satisfaction (82%) and faster delivery (75%), while traditional methods provide better cost control (68%) and structured workflows. The findings suggest that the choice of methodology should align with project needs and organisational goals. Agile is preferable for flexible projects, while traditional methods excel in predictable environments. The study recommends considering hybrid approaches, where initial phases use traditional planning, and agile execution follows to adapt to changing requirements.
