Data were collected through questionnaires and interviews, and the Statistical Package for Social Sciences (SPSS) version 23 was used to analyze the data. The findings indicated that stakeholder collaboration and partnerships significantly affect the implementation of youth development projects funded by BDF, with an adjusted r2 value of 0.737, explaining approximately 73% of the variations in implementation. The study concluded that the positive and very high correlation of 0.551 (55%) and the significant level at 0.01 (1%) with a p-value of 0.000 (0.0%) confirm a significant relationship between project management strategies and the implementation of youth development projects funded by BDF.
