In that regard, the research aimed at investigating the impact of leadership and culture on organisational performance. The research demonstrates that leadership and performance management affected the delivery of quality government services such as health, education, water, and agriculture, among a few. Due to the general necessity of ensuring public service accountability and customer focus, the New Public Management and Public Service models were associated with leadership and performance management as the conceptual frameworks. A desk review of secondary material revealed that employee performance and service delivery was affected due to the leadership strategy's bureaucratic and centralised nature. It was recommended that future research should focus on the impact of performance contracting and its effects on employee performance in the public service. http://pubs.sciepub.com/wjssh/9/2/1/wjssh-9-2-1.pdf evaluation leadership monitoring performance management public service public service delivery new public management Zambia
