APPLICATION OF VALUE STREAM MAPPING TO REDUCE LEAD TIME ON FRONT DOORTRIM PRODUCTS AT PT XYZ

Abstract

Productivity is a fundamental component in the success and sustainability of a company, playing a crucial role in gaining a competitive advantage. PT. XYZ, an automotive company, faces several challenges in its production process, particularly in the manufacturing of front door trim. The challenges in production process is Poor Inventory Control and Long Supplier Lead Time. with the total lead time 278.7 minutes which according to the management is hight. They want to reduce the lead time at least 10%. Due to the inefficiency in productivity and various wastes occurring in the production process, PT. XYZ aims to improve productivity by implementing Value Stream Mapping (VSM). This study identified that defect waste and waiting waste are the most frequent issues leading to Inefficient productivity. Through the application of VSM, the lead time in the production process was reduced by 16.3%, decreasing from 46.4 minutes before the implementation of VSM and Process Activity Mapping to 38.87 minutes, which is 7.57 minutes faster. This demonstrates that implementing VSM and Process Activity Mapping has successfully improved production efficiency at PT. XYZ.
