Enhancing Order Fulfillment Through Production Process Reengineering Using Manufacturing Execution System as a Reference Model

Order Fulfillment is a critical performance metric in company operations, directly linked to the effectiveness of process optimization and information integration. The ISA-95 standard sets a foundational guideline for the flow of information between control and management systems within organizations. At the core of this integration is the Manufacturing Execution System (MES), which functions as a shop floor information management system, capturing, integrating, and analyzing data to provide real-time insights into factory status on machine conditions, work-in-process, and production progress. This paper utilizes MES as a reference model, adopting the principles outlined in the ISA-95 standard to develop a framework for production process reengineering aimed at enhancing the order fulfillment. In this paper, a three-step guideline for reengineering the production process will be presented, with a machining factory serving as a practical case study. Through the reengineering of processes at this machining factory, this case company’s order fulfillment will be improved. While actual process reengineering has not yet been implemented at the case company, the proposed process reengineering plan has been officially endorsed by this case company, setting a path forward for future enhancement. An interview summary with the case company is provided in Section IV.
