Agile, Traditional, and Hybrid Approaches to Project Success: Is Hybrid a Poor Second Choice?

TLDR

The study examines three project management approaches: traditional, agile, and hybrid. Across 477 cross‑industry projects, 52% used hybrid methods, and regression analysis (R² 0.21–0.41) showed that hybrid and agile approaches significantly improve stakeholder success compared to traditional methods while maintaining equivalent budget, time, scope, and quality, confirming hybrid as a leading project management approach.

Abstract

Three project management approaches—traditional, agile, and hybrid—were considered in this study. Results from an international study, including 477 cross-industry projects, indicated that 52% of projects could be categorized as hybrid approaches. A regression analysis using multiple outcome measures indicated substantial explanatory power (0.21 < R 2 <0.41). Analysis suggested that hybrid and agile approaches significantly increase stakeholder success over traditional approaches while achieving the same budget, time, scope, and quality outcomes. Hybrid approaches were found to be similar in effectiveness to fully agile approaches. Results validate decisions by practitioners to combine agile and traditional practices and suggest that hybrid is a leading project management approach.
