Abstract: The main objective of the study was to establish the effect of quality management standards on customer satisfaction at Kenya Bureau of standards. The specific objectives of the study were to; examine the effect of quality planning on customer satisfaction, determine the effect of quality control on customer satisfaction, analyze the effect of quality assurance on customer satisfaction and assess the effect of continuous improvement on customer satisfaction at Kenya Bureau of standards. The study was guided by Total Quality Management (TQM) Theory, Systems Theory and Expectancy Theory. This study adopted the positivist research philosophy and correlation research design. This study targeted a total of 612 respondents comprising 92 quality assurance officers, 110 quality control inspectors, 80 quality planning/strategy officers, 120 customer service officers, and 210 customers of KEBS. Purposive sampling was employed. Closed questions were used to collect data. Data was presented using Tables. The study inferential statistics indicated that quality planning, quality control, quality assurance and continuous improvement have positive and statistically significant effect on customer satisfaction at Kenya Bureau of Standards. The study established that all quality management practices have a positive and statistically significant effect on customer satisfaction at the Kenya Bureau of Standards. Specifically, quality planning had a positive and significant effect (β = 0.459, p < 0.001), indicating that improved planning practices enhance customer satisfaction. Quality control recorded the strongest influence (β = 0.582, p < 0.001), suggesting that effective monitoring and compliance mechanisms play a critical role in improving service outcomes. Quality assurance also showed a positive and significant effect (β = 0.394, p < 0.01), highlighting the importance of consistency and reliability in service delivery. Additionally, continuous improvement demonstrated a positive and significant effect (β = 0.464, p < 0.001), implying that ongoing enhancements in processes and services contribute substantially to higher customer satisfaction. Overall, the findings indicate that strengthening all dimensions of quality management significantly improves customer satisfaction, with quality control having the greatest impact.
