Reducing Product Damage from Handling Process in the Warehouse of Srisawat Construction Materials Store

Abstract

This research aims to analyze the factors contributing to product damage and improve processes for handling goods. A qualitative research approach is used, with a population comprising 10 warehouse staff members from Srisawat Construction Materials Store. The sample size is determined using Krejcie and Morgan's sample size table. The primary research tool is the Fishbone diagram, which aids in identifying the root causes of product damage. Following this analysis, Work Instruction (WI) is developed as a guideline for operational procedures, and a preventive maintenance plan is established for handling equipment.The findings indicate that: 1) Product damage is primarily caused by inefficient staff performance, outdated handling equipment, and the use of unsuitable handling tools. 2) The implemented improvements have led to enhanced staff performance by developing work skills, introducing rest rotations, ensuring consistent work processes, and reducing employee fatigue. The use of the Fishbone diagram to pinpoint root causes, combined with Work Instruction (WI) as a standard procedure, has proven effective. These findings can be practically applied by utilizing the Fishbone diagram to identify underlying issues and adopting Work Instruction (WI) to standardize operational procedures.
