This paper aims to elaborate on the use of Six Sigma and Kaizen in policing services. Two case examples are discussed, followed by a review of the key implications obtained from the projects. In optimising the quality of policing services to the community, the police agencies in the UAE are faced with numerous challenges. This paper aims to provide further evidence of the use and applicability of Six Sigma and Kaizen in the policing field and to propose the direction for future studies. Based on the study results, it is proposed that the methodologies from Six Sigma and Kaizen are adopted in policing services to achieve an improvement in all aspects of their environment, including the process of service delivery, service effectiveness and efficiency, and the reduction of operational costs. This study is considered one of the few that have reported the use and benefits of these methods in policing services. Specifically, the findings have provided implications to the general arguments on the effectiveness of Six Sigma and Kaizen and their applicability in police agencies under the public sector, leading to further contributions which fill the research gap. Moreover, this study offers significant value for practitioners and managers in the organisations under the public sector to exert continuous improvement in the provision of services or products and organisational performance.
