Malaysian government has given a very high importance in developing the knowledge and skills among public service officers who are knowledge workers since human capital has been the key towards high performance achievement. However, there are many issues on unsatisfactory performance in public sector which were flagged by numerous audit reports and complaints received by Public Complaints Bureau. This paper fills the gap by examining the comprehensive literature in order to understand the relationship between knowledge productivity and knowledge worker performance. The aim of this paper is to identify knowledge productivity practices contributing to knowledge worker performance in public sector and to develop a conceptual framework supporting their relationship. The literatures reveals that there is a positive relationship between job related factors, human related factors, organizational commitment and knowledge worker performance. If empirically supported, this conceptual framework offers a new perspective on understanding knowledge productivity, organizational commitment and knowledge worker performance. This study also assists federal government to focus on factors related to knowledge productivity in order to further improve knowledge worker performance in public sector.
