Labour productivity was an important factor in the success of a company. A company’s output was as much dependent on labour productivity as it was on capital productivity. The study sought to examine the influence of quality circles on labour productivity in the judicial service in Nyeri County. The study adopted the descriptive design. The target population comprised 43 Magistrates, 93 Court Administrators, and 145 Lawyers (members of the Nyeri Law Society). Using 30% representation, a sample size of 13 Magistrates, 21 court administrators, and 44 Lawyers (members of the Nyeri Law Society) was utilized. The study used cluster random sampling to select 8 clusters, stratified sampling to identify the sample within each cluster, and simple random sampling to choose respondents from each stratum. It collected quantitative and qualitative data using questionnaires and interviews, then used statistical analysis to organize, summarize, and present the data. Quantitative data was analyzed with descriptive statistics (frequencies, percentages, means, and standard deviation) and presented in tables, graphs, and charts. The study demonstrates there is a very strong positive correlation between labour productivity in courts and quality circles, with a coefficient of 0.875 and a significance level of 0.000. This means that courts that implement quality circles tend to have higher levels of labour productivity The regression analysis shows that technology use significantly enhances productivity, with a one-unit increase resulting in a 0.265 standard deviation rise (Beta = 0.265, p = .026). The study recommended that the judicial service should improve the technology infrastructure to boost productivity and performance in the legal sector.
