The 2023 Compendium of Innovation and Productivity Initiatives in the Public Sector results from extensive outreach, data gathering, and analysis to identify leading best practices in public-sector productivity across the Philippines. The report describes 20 improvement initiatives that were successfully implemented, highlighting their potential replicability. Each entry in this inventory can also be further expanded into an individual case study, allowing for the most compelling success stories to be promoted, disseminated, replicated, and used to enhance trust in the public sector and motivate public servants to strive for excellence.
