How workers actually access instructions, specs, and documentation today — not vendor marketing
← Back to Manufacturing Jobs Index
Context: This page expands on a question that came up while reviewing the Aerospace JTBD Research — specifically, what does "computer-generated traveler" actually mean in practice? How do workers really access instructions today?
How do workers get the information they need to do their job?
Printed travelers, binders, laminated cards at station
Still dominantShared workstation PC, walk up to look up specs
CommonRugged iPad/Android, digital work instructions
GrowingHoloLens, projected overlays on work
Pilots only| Industry | Primary Method | Digital Adoption | Key Constraints |
|---|---|---|---|
| Aerospace | Paper travelers + MES terminals | Low–Medium | Huge structures, spotty WiFi inside metal, AS9100 audit trails |
| Automotive | Laminated station cards + andon boards | Medium | Takt time pressure, standardized work already optimized |
| Power Electronics | Paper travelers, MES kiosks | Low–Medium | High-mix, test data logging still manual |
| Medical Devices | Paper DHR binders | Low | 21 CFR Part 11 validation burden, multi-signature requirements |
Software vendors (Tulip, Parsable, Poka, etc.) sell tablet-based digital work instructions. The pitch: "eliminate paper, get real-time visibility, improve quality."
The reality:
A packet of printed work orders, drawings, and checklists that physically travels with the unit through assembly. Workers sign off each step by hand. Still the backbone of aerospace and medical device manufacturing.
Pros: Always available, no IT dependencies, legally defensible signatures
Cons: Version control nightmares, lost packets, no real-time visibility
Shared PC at the workstation. Worker walks over to look up specs, drawings, or current revision. May also be where they clock time or sign off digitally.
Common systems: SAP ME, Siemens Opcenter, Rockwell FactoryTalk, Boeing Velocity/CMES
Pros: Centralized data, audit trails, connects to ERP
Cons: Worker leaves station, shared login issues, clunky UX
iPad or Android device (often in a protective case) with digital work instructions app. Worker carries it or mounts at station. Can include photos, videos, interactive checklists.
Common platforms: Tulip, Parsable, Poka, Dozuki, Augmentir, PTC Vuforia
Pros: Instructions at point of use, multimedia, data capture
Cons: Battery life, WiFi connectivity, device management, change control
HoloLens, Magic Leap, or smart glasses that project instructions or wiring diagrams directly onto the work. Hands stay free. Boeing and Airbus have piloted for wire harness routing.
Pros: Hands-free, 3D overlay on actual parts, wow factor
Cons: Expensive ($3-5K/device), battery (2-3 hrs), worker acceptance, narrow FOV
