The study examined the influence of internal control measures on the financial performance of KTDA-managed factories in Kenya, focusing specifically on internal audit controls and risk assessment. Using a descriptive research design, data were collected from 111 employees across various roles through questionnaires. The findings revealed that risk assessment practices like stock-taking and access control positively impact financial performance, while weak adherence to cash reconciliation and document reviews hinders effectiveness. Segregation of duties and well-defined operational procedures were found to be the most influential in improving financial outcomes. Although internal audit controls and risk assessment also play a role, their direct effects are less pronounced. The study recommends staff training on risk assessment procedures and refining operational processes, particularly in areas related to risk mitigation and accuracy of financial records.
