Application of Six Sigma Methodology for Reducing Repair Time Case Study: Iran KhodroAgent

In recent years, many companies have used different types of quality programs such as total quality management, reengineering, value engineering, lean production, and six sigma in order to increase customer satisfaction and reduce quality cost. Among all these programs, six sigma is one of the most powerful tools for problem solving. Iran Khodro Company has begun using this methodology in Isaco. This paper demonstrates the executive progress of reducing time of car repair in one of Iran Khodro agents in Shiraz city. DMAIC problem solving approach was used for this project. The aim of this project is to increase customer satisfaction and increase agent revenue. Implementing this approach, vehicle clearance and store were identified as critical to quality divisions. So, making amendments in these areas reduces the repair time.
