Defective Coffee Beans Reduction: A Case Study of Small-scale Coffee Beans Production in Shan State, Myanmar
Keywords:
Coffee Beans, Defective, Arabica, Immature Beans, Parchment, and Broken at Dry MillAbstract
This case study focuses on how Lean Six Sigma methodology can be applied to enhance performance and support the creation of business improvement activities.The main objectives of this case study on coffee production are to identify the underlying reasons for the high defect rates of coffee green beans and to find out the most efficient ways to address the issue, make it better and more durable, and implement the solution within the company. The processes were carried out by applying Lean Six Sigma, such as DMAIC, to expedite the procedure and systematic thinking. A detailed analysis method, including Measurement System Analysis (MSA), SIPOC, Process Map, Pareto Chart, and Fishbone Diagram, identifies potential causes and offers possible corrective measures.One of the main issues faced by Jadae Akha Coffee is the high rate of defects in coffee beans caused by poor farming techniques, a lack of equipment (a Refractometer, a tool for checking Brix or sugar content, to examine the coffee cherries' level of sugar content at 18 degrees or ripeness before beginning the harvesting process), inexperienced workers, and insufficient handling experience of hulling machines, which has a substantial negative
