An integrated engineering change management process model for a project-based manufacturing

In a project-based ETO (Engineering-To-Order) industry, design, purchasing, production and quality processes are closely integrated to meet a delivery schedule, cost limitation and quality specification. When an engineering change occurs in a project execution stage, miscommunication of design change may generate a significant cost and delay. This paper suggests a model to capture a design change and share activities for processing change done by each stakeholder. The framework also captures ECR (Engineering Change Request), ECO (Engineering Change Order) and a relationship among them with a result of processes. The data could be used for analysing defects of each process, improving a design quality, and a plan for cost reduction. For capturing, sharing and monitoring every change of drawing element and BOM (Bill of Materials), the model extracts a drawing and BOM from a product structure of a 3D CAD (Computer-Aided Design) system. Extracted data are sent to PLM (Product Life-Cycle Management)/ERP (Enterprise Resource Planning) system for planning, purchasing, manufacturing and quality control processes.
