Software project management is characterized by its intricate nature, often hindered by the volatile dynamics of software development. Conventional management approaches struggle to address the uncertainties that arise in such contexts. This study delves into the synergistic fusion of fuzzy logic and Six Sigma methodologies to refine software project management. Fuzzy logic adeptly navigates uncertainty, while Six Sigma employs a data-driven strategy for process enhancement. This research investigates the amalgamation of these methodologies to optimize software project management, ultimately leading to heightened project outcomes, diminished risks, and amplified stakeholder contentment.
