Lean Manufacturing Strategy to Improve Efficiency of Goods Preparation and Delivery with PDCA Method

This study focuses on the implementation of Lean Manufacturing principles to enhance the efficiency of goods preparation and delivery processes in a warehouse setting. The primary objective is to reduce the time taken for preparation and delivery while simultaneously increasing productivity. The research employs the PDCA (Plan- Do-Check-Act) methodology to systematically identify and address factors contributing to delays and waste in the preparation and delivery processes. In the “Plan†phase, an analysis of the current operational processes is conducted using Lean tools such as 5W + 1H and fishbone diagrams to identify inefficiencies. The “Do†phase involves implementing improvements, including reorganizing the warehouse layout and introducing stock leveling techniques to optimize item placement. The “Check†phase evaluates the effectiveness of these changes, revealing a 33% reduction in preparation and delivery time, alongside a 38% increase in productivity. The findings indicate that the application of Lean Manufacturing through the PDCA method has successfully streamlined the goods preparation cycle, leading to enhanced operational efficiency in the warehouse. This improvement not only meets but exceeds the initial targets set for preparation time and productivity, ultimately contributing to higher customer satisfaction through timely and reliable deliveries. The study concludes that Lean Manufacturing strategies can serve as a valuable framework for other organizations aiming to improve their operational performance and achieve competitive advantages in the market.
