According to the 2025 World Happiness Report, Philippines ranks as the 57th happiest country, with Finland as the happiest and Afghanistan as the least happy, while ranking 4th in Southeast Asia. While happiness index serves as essential metric for assessing a country's mental and emotional well-being, it can be used as a valuable quality indicator of collaborative Projects, Programs, and Activities (PPAs) between organizations and its local government. This research aimed to evaluate the extent and quality of collaborative practices of the LGU Makati as seen under the lens of affiliates of the Federation of Makati Cooperatives (FEMACO). The study employed surveys, key informant interviews, and group discussions between cooperative leaders and local government officials. A t-test was conducted to determine significant difference in happiness indices between respondents: the Board of Directors and LGU Officials. Findings revealed that FEMACO affiliates displayed varying happiness indices in relation to the extent of collaborative practices in terms of compliance to laws and circulars, recognition programs, technical support, capacity building, promotional activities, and partnership and linkages. The study shed light on the perceptions, inclusiveness, and collaborative values essential for promotion and growth of cooperatives as instruments of social justice, equity and economic development. Finally, the study highlights internal and external challenges experienced by affiliates on PPAs collaboration. Ultimately, the study recommends not only expanding collaboration with the LGU but also forging partnerships with Civil Society Organizations (CSOs) and community groups to create inclusive and empowered cooperatives essential in realizing the SDG of 2030.
