PDM Product Data Management

Scenario Challenges

• Drawings, BOMs, and process documents exist in multiple versions with inconsistent definitions.
• Engineering changes still depend on email or offline communication, making the process risky and hard to trace.
• Data handoff from design to manufacturing is delayed, affecting execution accuracy.
• Audit and quality traceability lack a single trusted data baseline.

Module Positioning

PDM serves as the product master-data center, managing the core objects that connect engineering and manufacturing so collaboration is not distorted by multiple versions, multiple definitions, and multiple disconnected systems.

Master Data Objects

• Drawings and technical documents: centralized archiving, version control, and access control.
• BOM and substitute materials: structured maintenance with change records.
• Process and standards: linked process versions, inspection criteria, and release status.
• Change records: complete engineering-change approval history.

Core Workflow

1. Create, review, and release documents.
2. Maintain, validate, and publish BOM structures.
3. Submit, evaluate, approve, and execute engineering changes.
4. Synchronize change results to manufacturing, procurement, and collaboration systems.

Key Deliverables

• Product master-data model and naming/coding standard.
• Version-control mechanism and permission strategy.
• Engineering change process and approval rules.
• Cross-system data synchronization and mapping scheme.

Integration Relationships

• Provide version baselines for collaborative design and auto-drawing.
• Provide executable process and material versions to T-MOM and MES.
• Share controlled product data with the supply-chain platform to reduce version and material mistakes.

Metrics and Value

• Reduce rework and delays caused by inconsistent versions.
• Improve cross-functional coordination and change-execution accuracy.
• Strengthen quality traceability, audit retention, and compliance management.
