Manufacturing Aerospace

The Need

Your engineering team identifies a design flaw during production. They need to change a specification on drawing V3. But production is already building units to V3 specs. Quality is inspecting against V3 specs. Suppliers are manufacturing components for V3. If the change isn't coordinated across all these teams, you get chaos: some units built to old specs, some to new specs, creating rework. Inventory of old components becomes obsolete. Customers receive inconsistent products.

Changes happen through email chains and spreadsheets. Change status is unknown. Multiple drawing versions circulate. Suppliers unknowingly ship components to obsolete specs. Production schedules don't account for changeover timing. Quality uses outdated specifications. Regulatory auditors discover undocumented changes.

For aerospace, automotive, and medical device manufacturing with long lead times, the problem multiplies. A six-month lead-time component can't change specification at the last minute. Changes must be planned months in advance. But most organizations lack discipline for effective planning. Last-minute changes force expedited production, emergency procurement, or design freezes that delay market launch.

A single uncontrolled change costs $100,000+ in aerospace or medical device manufacturing—investigation, correction, regulatory fines. Scrap rates increase. Suppliers get disrupted. Regulatory compliance fails.

The Idea

An engineer initiates an ECO with description, justification, reason for change, proposed effective date, and initial impact assessment. The system automatically analyzes impact: which drawing revisions are affected, which BOMs, which suppliers, which active production orders, which customers. Not guesswork. Data-driven impact analysis pulling exact numbers from your manufacturing system.

The system generates a structured approval workflow based on change type and impact. Simple design refinement requires engineering and quality sign-off. Component substitution requires engineering, quality, procurement, and manufacturing. Changes affecting customer products require customer approval. Each stakeholder gets role-specific context: manufacturing sees production impact and changeover timing; procurement sees which suppliers to notify; quality sees specification changes; customers see whether the change affects them.

Effectivity becomes transparent. The approver specifies effective date: "Change effective for all new production orders starting 2024-12-01." The system enforces this: orders before effective date use old specs; orders after use new specs. Orders currently in production show whether they're affected with recommendations: "This order due 2024-11-25, change effective 2024-12-01. Recommendation: complete using old spec or expedite to incorporate new spec."

Inventory impact is calculated automatically: "Old component inventory (5,420 units) becomes obsolete on effective date. Value: $127,000. Recommendation: consume old inventory in orders 1-47, purchase new component starting order 48." System manages buy-out strategies and supplier adjustment negotiations.

Supplier notification is auditable. System generates change notices with technical details, effective date, and required acknowledgment. Notifications transmitted electronically with receipt tracking. Supplier acknowledgment is required. Qualification status for new suppliers is tracked: "New supplier XYZ approved as alternative. Status: samples in testing. Expected approval 2024-12-15. Cannot use until qualification complete."

Quality procedures are automatically flagged for update: "QPS-2024-001 (inspection procedure) marked for revision due to dimensional requirement change. Revision due 2024-11-25, change effective 2024-12-01." System requires updated procedures before effective date.

Revision control is automatic. Every affected document (drawing, BOM, procedure) is automatically versioned. System maintains complete change history: "Component Type-D: Rev A (production until 2024-11-30), Rev B (effective 2024-12-01 per ECO-2024-147)."

For regulated industries (aerospace AS9100, pharma 21 CFR Part 11, medical device ISO 13485), system generates compliant regulatory documentation with immutable audit trails and electronic signatures at each approval stage.

Deployment options include on-premise installation, deployment on your cloud (AWS, Azure, GCP), or fully managed IoTReady-hosted solutions. All deployment models include identical enterprise features.

OTP includes built-in backup and restore, AI-powered assistance for data analysis and anomaly detection, integrated business intelligence dashboards, and spreadsheet-style data exploration. Role-based access control ensures appropriate information visibility across your organization.

Frequently Asked Questions

What is an engineering change order and why does it matter?
An engineering change order (ECO) or engineering change notice (ECN) is a formal request to modify a product design, component specification, or manufacturing process. It matters because uncontrolled changes lead to production of conflicting specs, supplier confusion, regulatory non-compliance, and costly recalls. A disciplined ECO process ensures all departments approve changes before implementation and enforces consistent specifications across production.
How does change request tracking reduce manufacturing costs and delays?
By automating impact analysis, change trackers identify which products, suppliers, and work orders are affected—preventing last-minute surprises that cause scrap and rework. The system calculates changeover timing requirements so production schedules account for specification transitions. It eliminates manual email coordination, reducing approval cycles from weeks to days and enabling predictable, controlled production changeovers.
How does a change request system ensure regulatory compliance in aerospace and medical device manufacturing?
Regulatory compliance requires immutable audit trails of all change decisions with timestamps and approver identity. The system automatically generates compliance documentation for AS9100 (aerospace), ISO 13485 (medical device), and 21 CFR Part 11 (pharma) standards. It maintains electronic signatures at each approval stage, links changes to design control documentation, and ensures that quality procedures are updated before new specifications take effect—critical for regulatory audits and product recalls.
What happens to inventory when a component change is approved?
The system automatically calculates the impact: quantity of old material in inventory, consumption rate before the effective date, inventory that becomes obsolete, and estimated scrap value. It can recommend buy-out strategies (purchasing the last batch of old components at favorable pricing before the supplier discontinues them) or negotiating supplier adjustments, potentially recovering thousands in obsolescence costs.
How does a change request tracker notify suppliers and confirm they understand the change?
The system generates supplier change notices with technical details and effective dates, transmits them electronically, tracks receipt, and requires formal acknowledgment of understanding. For aerospace suppliers, it can format notices to meet AS9102 requirements. If a supplier misses an acknowledgment deadline, the system escalates to procurement, ensuring suppliers don't manufacture components to obsolete specifications.
Can a change request system integrate with our existing ERP and MES systems?
Yes. The system queries your drawing management, BOM, supplier database, production planning, and customer management systems to automatically identify affected items. It integrates with ERP/MES to enforce drawing and BOM revisions based on effective dates, ensuring production orders created before the effective date use old specifications and orders created after use new specifications. It also integrates with quality procedure systems to flag updates required before the effective date.
How long does it typically take to approve and implement an engineering change?
Manual email-based processes often take 2-4 weeks with multiple rounds of coordination and lost emails. An automated system typically reduces approval cycles to 3-5 days by routing structured requests to each stakeholder with role-specific context and supporting impact analysis. For simple design refinements requiring only engineering and quality sign-off, approval can complete in 1-2 days, enabling faster time-to-market for cost reductions and process improvements.
