Statistical Process Control (SPC) is an effective powerful methodology for analyzing, monitoring, managing, and improving process performance. The purpose of this study is to introduce Statistical Process Control technique in Yazd ceramic tile manufacturing plant in Iran for reducing
unwanted ceramic tile defects and wastages. Defects were categorized on their frequencies by examining defective tiles produced in the manufacturing plant. The most important defect was a variety of cracks in different tiles. By implementing control diagrams R, X and six-pack for a
sensitive parameter, a significant result was observed. Also, system troubleshooting was performed by examining the process and its related machines. After identifying and resolving the given defect and reevaluating the process by the mentioned diagrams, the quality of observed ceramic tiles were improved significantly. Hence, this study presents a complete process to help manufacturer identify defects for
process improvement with immediate benefits for the current development cycle in the plant.
