The Impact of Lean Tools and Waste Analysis on the Improvement of Process Cycle Efficiency and Manufacturing Lead Time of Pipe Sleeve Fabrication: A Case Study

This study investigates the implementation of lean tools to enhance process cycle efficiency and reduce production lead time by at least 10% in a case study of pipe sleeve fabrication at one of manufacturing company in Indonesia. Improving production efficiency is a critical investment for manufacture sustainability and competitive advantages. The application of lean tools, such as value stream mapping and pareto analysis, can help reduce process inefficiencies by eliminating non-value-added activities, such as machine breakdowns, waiting, and material handling. The results demonstrate that the implementation of lean tools can increase Process Cycle Efficiency (PCE) from 39.76% to 51.40% and reduce Manufacturing Lead Time (MLT) by 22.63%. This case study provides insights into how lean tools can be applied to improve productivity in manufacturing processes. Lean tools can be implemented across various manufacturing industries to enhance their productivity. Broader implications of implementing lean method suggest that companies can enhance productivity, reduce cost of production, improve quality, and ultimately increase their competitive advantage in the market.
