Poor implementation of devolution hinders effective planning and efficient service delivery. The performance of governors is based on infrastructure development, governance, safe water provision, health, housing, food security, investment opportunities, manufacturing, public participation, social services, emergency services, urban development, poverty eradication, youth empowerment, women empowerment, economic growth initiatives, delivery of basic services, ability to self-generate revenue to reduce reliance on national government, and governor’s leadership capabilities.
