Engineering Change Order (ECO) is een begrip binnen de industriële digitalisering en productstructuur & documentatie.
Definitie
Engineering Change Order (ECO) is een gecontroleerd proces voor het formeel wijzigen van product ontwerp, documentatie, processen of specificaties. Het ECO systeem waarborgt dat alle wijzigingen systematisch worden beoordeeld, goedgekeurd en geïmplementeerd met volledige impact analyse en traceability.
Kenmerken
- Change request formalisatie: Gestructureerde aanvraag met reden en impact assessment
- Approval workflow: Multi-disciplinaire review en goedkeuring proces
- Impact analyse: Complete assessment van technische, cost en schedule gevolgen
- Effectiviteits planning: When-effectief dates en implementation timeline
- Document controle: Automatic update van alle gerelateerde documentatie
- Traceability: Complete audit trail van change rationale en implementation
- Cross-functional coordination: Engineering, manufacturing, quality, sourcing alignment
- Customer communication: Formal notification waar contractueel vereist
Toepassing
Design wijzigingen:
- eBOM updates: Component additions, deletions, substitutions
- CAD model changes: Dimensional updates, feature modifications, interface changes
- Material specifications: Grade changes, surface treatments, heat treatment updates
- Tolerance adjustments: GD&T modifications, fit en clearance updates
Manufacturing process changes:
- mBOM modifications: Production structure en assembly sequence updates
- Routing changes: Work center modifications, operation additions/deletions
- Tooling updates: Fixture changes, cutting tool specifications, setup procedures
- Control plan revisions: Quality control point modifications
ECO proces flow:
- Change request: Problem identification en proposed solution documentation
- Preliminary assessment: Engineering feasibility en initial impact estimate
- Formal review: Cross-functional team evaluation en approval/rejection
- Implementation planning: Timeline, resources, communication plan development
- Execution: Controlled rollout met FAI validation waar needed
- Closure: Effectiveness verification en lessons learned capture
Metaalindustrie ECO drivers:
- Design optimization: Weight reduction, cost improvements, performance enhancements
- Manufacturability: DFM improvements, tooling optimization, assembly simplification
- Quality improvements: CAPA driven design changes
- Supplier changes: Alternative sourcing, supplier capability changes
- Regulatory compliance: Standards updates, certification requirement changes
- Cost reduction: Material substitution, process improvements, design simplification
Digital ECO management:
- PLM integration: Automated workflow en document control
- ERP synchronization: BOM updates, costing updates, MRP re-calculation
- MES updates: Work instruction changes, quality plan updates
- Supplier portals: Automatic notification van affected suppliers
