This analysis reveals time wastage issues in aircraft maintenance operations, suggesting lean six sigma methods improve efficiency.
The global Maintenance, Repair, and Overhaul (MRO) industry are experiencing significant growth, particularly in wide body and narrow body aircraft segments. However, operational efficiency challenges persist, as demonstrated by excessive time wastage during the installation process within an Indonesian MRO company. This paper employs the Lean Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) framework to identify and address the root causes of this time wastage. Through Value Stream Mapping, Why-Why Analysis, and the implementation of innovative solutions such as a dedicated screw box and QR code stickers for material management, this research aims to streamline the installation process, reduce waste, and improve overall efficiency. The anticipated outcomes include a remarkable 40-minute reduction in material search time, an 80% increase in Process Cycle Efficiency (PCE), and a substantial and lasting improvement in value-added job task efficiency. This study contributes valuable insights to the aviation maintenance sector's pursuit of operational excellence and customer satisfaction.
