The findings reveal whether the production and distribution process of paracetamol remains within acceptable quality control limits or exhibits significant variations that may compromise drug safety and effectiveness. Results indicate the presence or absence of out-of-control conditions, providing insight into process stability and areas requiring improvement. The study highlights the importance of applying statistical quality control techniques in pharmaceutical retail settings to ensure compliance with health standards and enhance consumer confidence. It is concluded that the use of p-chart and c-chart offers an effective approach for monitoring and improving the quality performance of paracetamol. Recommendations are made for regular quality assessment, improved handling practices, and adherence to regulatory standards to maintain product integrity and safeguard public health.
