Abstract

The purpose of this study is to increase the efficiency of the goods receipt and return process, using the convenience store as a case study.  The study had employed the 5W1H methodology to analyze the detailed processes, to find issues and their root causes, and to identify waste. It was found that there are two main processes with problems – the process of Goods Receipt and Transfer of Goods Receipt data. There are also various processes that face discontinuity in the flow. To address these issues, the processes had been re-designed under the Lean concept and Eliminate Combine Rearrange Simplify (ECRS) guidelines by leveraging improved technology to enable real time information feedback, streamline processes, and reduced wastage in scanning and receipt processes.  This was put to the test at 29 convenience stores, by capturing before and after data over a period of 60 days.


It was found that the new process shortens the time, on average from 44.00 minutes to 30.50 minutes or equivalent to 31% of reduction. Therefore, the company could increase productivity and reduce the total cost of operations. Moreover, the proposed concepts in this study could be applied for other products group or used as the guideline for other suppliers with whom may have the same business model in the future.
