The progressive cavity pump market is in high demand, serving key industries such as automotive, electronics, pharmaceuticals, and food and beverages. This research applies the Integration Definition for Function Modeling (IDEF0) and the Supply Chain Operations Reference (SCOR) framework to analyze supply chain processes. It examines the challenges faced by a Japanese progressive cavity pump manufacturer that has expanded operations to Thailand and proposes strategic guidelines to enhance supply chain efficiency. The study identifies critical issues across pre-production, production, and post-production stages, making complex operations more manageable and easier to visualize. These issues include market trend analysis, customer feedback integration, demand planning, online data connectivity, supplier evaluation, predictive maintenance management, international transportation, real-time tracking, and defective product management. Addressing these challenges can improve overall production management, support global product expansion, particularly in Thailand and Southeast Asia, enhance customer requirement understanding, and mitigate risks to operational efficiency. This approach strengthens the company’s competitive advantage by optimizing supply chain processes and delivering superior products and services to end users.
