          The objective of this study is to analyze problems caused by the ceramic production process of a case study of a ceramic company in Samut Prakan Province by using the Supply Chain Operations Reference: SCOR Model and to propose alternative solutions to increase the efficiency of the ceramic production process. The Supply Chain Operations Reference (SCOR Model) is used as a framework for data collection by observing and studying work processes from actual work operations together with the analysis with the Flow Process Chart, Flow diagram, Value Added (VA) and Non Value Added (NVA) activities, including the necessary and unnecessary activities in conjunction with the ECRS (Eliminate, Combine, Rearrange and Simplify) which is the principles to identify waste and unnecessary steps from the process and find ways to improve it. The result shows that there are 3 and 16 wasteful activities in the planning and production processes respectively. Therefore, the solution to reduce waste in the planning and production processes by reducing cycle time. The result of research shows that the planning process and production process after the improvement has been reduced the cycle time 17.16 hours and 5.87 hours respectively. This solution can produce more pieces per day and increase work efficiency which is beneficial to the business operations in the future.
