This project was aimed to improve the inventory control system by applying Six Sigma DMARC framework, which integrated the DMAIC and DMADV methods. The project utilized other quality assessment tools, including Pareto chart, Fishbone diagram, Kano model, and Quality Function Development (QFD). These tools were used to gather voice of customer, define the problem, measure process performance, analyze the root causes, improve the process performance, and control the progress made. With the introduction of radio-frequency identification (RFID) into our inventory- checking procedures, results showed that there were 47% reduction in the procedures, 53% reduction in the time, 53% reduction in the number of labors involved in the inventory- checking process. An increase in customer satisfaction from 3.93 to 4.23 was also observed. Our findings suggested that the implementation of the new system increased efficiency, reduced cost, and increased user satisfaction.

為簡化財產盤點作業，本文應用六標準差管理步驟流程DMARC (即六標準差方法論之DMAIC作業改善與六標準差設計方法的DMADV) 進行改善。過程中並搭配運用柏拉圖、魚骨圖、Kano model及QFD等品質工具，來蒐集顧客聲音、界定問題、衡量現況、分析原因、設計新流程與服務及維持改善成效，以符合顧客需求。經改善後，導入新的RFID盤點作業系統及盤點工具，可減少盤點作業流程約47%，減少作業時間約53%及節省人力約53%，顧客滿意度由原3.93提升到4.23，使財產盤點作業更簡化、快速及節省作業人力。
