Abstract:This study sought to investigate the performance improvement through benchmarking in commercial banks in Kenya by focusing on the extent to which commercial banks used benchmarking, the relationship between benchmarking and organizational performance, and the challenges facing the adoption and implementation of benchmarking. Simple Random sampling technique was used to select two respondents from each bank. Both descriptive and inferential statistics were applied and Statistics Package for Social Sciences (SPSS) for windows version 20.0 was used for analysis. The analysis indicated that on overall, benchmarking has a positive and significant correlation r =0.551 and p< 0.001with organizational performance. The results indicated that benchmarking was an established performance improvement technique that was proved to be effective in the banking industry in Kenya over time. The researchers recommend that the benchmarking initiatives should incorporate the divergent views of all employees since at the end of it all these employees will need the information to improve the process.
