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?

The Delivery Spectrum

How do workers get the information they need to do their job?

📄 Paper

Printed travelers, binders, laminated cards at station

Still dominant

🖥️ Fixed Kiosk

Shared workstation PC, walk up to look up specs

Common

📱 Tablet

Rugged iPad/Android, digital work instructions

Growing

🥽 AR Glasses

HoloLens, projected overlays on work

Pilots only

Reality by Industry

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

The Vendor vs. Reality Gap

Software vendors (Tulip, Parsable, Poka, etc.) sell tablet-based digital work instructions. The pitch: "eliminate paper, get real-time visibility, improve quality."

The reality:

Information Delivery Methods

Paper Travelers

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

MES Kiosk / Fixed Terminal

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

Rugged Tablets

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

AR Glasses / Head-Mounted Displays

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
