How do I choose between different shop floor control systems for commercial aerospace production?

Choosing a shop floor control system for commercial aerospace production is mostly about matching the system to your quality, traceability, compliance, and production complexity needs—not just picking the most feature-rich software.

1) Start with aerospace-specific requirements

Commercial aerospace usually needs more than basic manufacturing execution. Make sure the system can support:

• Full lot/serial traceability
• AS9100 / AS9145 / FAA / customer compliance support
• First article inspection (FAI) support
• Nonconformance, MRB, and deviation workflows
• Tool calibration control
• Operator certification and training qualification tracking
• Traveler/routing control with revision history
• Electronic signoff and audit trail
• Configuration management and engineering change control
• Material pedigree and certificate of conformity tracking
• Quality records retention

If a system cannot reliably handle those, it’s usually not a fit for aerospace.

2) Decide what kind of shop floor system you actually need

Different products get called “shop floor control,” but they’re not all the same.

A. Basic tracking / work order system

Good for:

• Simple routing visibility
• Labor booking
• WIP status updates

Not enough if you need:

• Strong quality workflows
• Paperless travelers
• Real-time compliance evidence

B. MES / shop floor execution system

Good for:

• Paperless production
• Enforcement of process steps
• Data collection
• Traceability
• Quality integration

Usually the best fit for aerospace production.

C. ERP module with shop floor functions

Good for:

• Inventory, planning, purchasing, costing
• Light production visibility

Often weak on:

• Detailed execution
• Inspection workflows
• Advanced traceability
• Aerospace-specific compliance

3) Evaluate the key capabilities

Use a scorecard and compare vendors against these areas:

Traceability

Can it track:

• Raw material heat/lot
• Serialized parts and subassemblies
• Tooling used
• Operator, machine, date/time
• Process parameters
• Inspection results
• Rework history

Quality control

Does it support:

• In-process and final inspection
• SPC / process control
• NCMR / NCR workflows
• MRB disposition
• Holds and releases
• Deviations / concessions / waivers

Document and revision control

Can it ensure operators see only the current:

• Drawing
• Work instruction
• Spec
• Route
• Tooling list
• Inspection plan

Compliance and auditability

Look for:

• Immutable audit trails
• Electronic signatures
• User access control
• Record retention policies
• Exportable audit reports

Integration

It should integrate with:

• ERP
• PLM
• QMS
• CAD/CAM, CMM, barcode/RFID systems
• Tool calibration systems
• Test equipment and IoT devices

Scheduling and dispatch

Depending on your operation, you may need:

• Finite scheduling
• Dispatch lists
• Work center loading
• Constraint management
• Priority-based job release

Usability on the shop floor

If operators hate it, it will fail. Check:

• Touchscreen usability
• Barcode scanning
• Offline capability
• Error-proofing / poka-yoke prompts
• Ease of training

4) Match the system to your manufacturing environment

Your choice depends heavily on the type of aerospace work you do:

• Machining / fabrication: strong machine integration, labor tracking, tool control
• Assembly: traveler management, torque traceability, step-by-step signoff
• Special processes: parameter capture, certification records, controlled process evidence
• Electronics/avionics: component genealogy, ESD/process control, serialization
• MRO / aftermarket: repair history, part interchangeability, service records

5) Check implementation fit, not just software features

A good system can fail if implementation is poor. Evaluate:

• Vendor aerospace experience
• Implementation methodology
• Support model and response times
• Configuration vs. customization approach
• Upgrade path
• Data migration effort
• Validation support if needed
• Total cost of ownership

Avoid excessive customization unless absolutely necessary. In aerospace, clean configuration is usually safer than hard-coded changes.

6) Build a weighted decision matrix

Create criteria and weights. Example:

• Traceability – 20%
• Quality workflows – 20%
• Compliance/auditability – 15%
• Integration – 15%
• Usability – 10%
• Scheduling – 10%
• Vendor support – 10%

Score each system 1–5 and compare totals. Weight the things that matter most to your operation.

7) Run a pilot with real jobs

Before buying:

• Test on a real work order
• Use real travelers, inspections, and deviations
• Include at least one complex part or assembly
• Involve operators, quality, planners, and supervisors
• Measure cycle time, errors, and data completeness

A demo is not enough. You want a pilot that exposes pain points.

8) Common red flags

Be cautious if the system:

• Can’t enforce process sequence
• Handles traceability only in spreadsheets
• Has weak audit trails
• Requires lots of manual re-entry
• Doesn’t support revision control cleanly
• Can’t integrate with your ERP/QMS
• Needs heavy customization for basic aerospace needs

9) A practical short list of questions to ask vendors

• How do you support full genealogy and serial/lot traceability?
• How do you handle NCR/MRB/rework workflows?
• Can you support electronic travelers and signoffs?
• How do you prevent obsolete revisions from being used?
• What aerospace customers do you support today?
• How do you integrate with ERP, QMS, and PLM?
• What is your approach to validation and audit readiness?
• What are the implementation timeline and hidden costs?
• How do you handle offline shop floor operation?
• Can we run a pilot using our actual part family?

10) Rule of thumb

For commercial aerospace, choose the system that best combines:

1. Traceability
2. Quality control
3. Compliance
4. Integration
5. Shop floor usability
