Operator tablet kiosk

Tablet work instructions for every workstation.

Paper travelers are a 1980s answer to the question "how does the operator know what to build?". And they're the single biggest source of audit findings, version mix-ups, and quality holds in SMB manufacturing today. Ignite Lean replaces them with a $200 tablet you already own. Badge in, walk the sequence, flag what's wrong with a photo, hand off the finished serial. No native app, no IT project, no per-seat scanner-gun budget.

The workflow

Pair, badge, build

A device-token QR code from the admin pairs the tablet to a specific workstation (caliper sub-assembly, wiring-harness route, paint cell). After that, the tablet auto-loads the kiosk on boot. An operator badges in via short PIN or printable QR badge. That identifies them at the workstation. They pick the next unit off the queue (or scan a parent serial off the rack), and the build flow begins: step 1, step 2, step 3, commit. The operator never sees a paper traveler, the kiosk never sees an unauthorised user.

  • One-time device pairing via admin QR code
  • Kiosk auto-loads on boot. No separate login per shift
  • Operator badge-in via PIN or printable QR badge
  • Pick from station queue or scan a parent serial to start
  • Step-by-step build flow with embedded WI + scan validation
  • Auto-commit on the last step → unit moves to the next workstation's queue

Visual work instructions on every step

The latest revision. On the right step.

Each build step can attach a visual work instruction. The one engineering just published, with the rotor, the four bolts, the torque values. The operator sees the WI rendered as a full-screen page, can pinch-zoom for detail, tap through multi-page documents, and tap a callout to highlight it. The WI lives on the work_instructions row; when engineering edits it, the next badge-in renders the new version. No floor swap, no toolbox talk, no risk of the off-shift crew running yesterday's revision.

  • Visual WI attached at the step level. Engineering controls per-step
  • Pinch-zoom for detail, tap through multi-page documents
  • Always renders the latest published version (closes ISO 9001 7.5.3.2)
  • Falls back to a markdown notes block when no visual WI is attached
  • View any past revision from the build history (auditor view)

Scan-validated parts

Wrong rotor in the right hand? Build halts.

For tasks that risk part mix-up. A 295mm rotor on a 280mm caliper. Flip on scan-required at the engineering workbench. The kiosk then demands a barcode scan before that step can complete, validates the scan against the expected part number, and halts the build with a clear error if it doesn't match. No need for a dedicated scanner gun. Most tablet camera apps and cheap USB scanners both work via the browser's scan input.

  • Per-task scan-required toggle from the engineering workbench
  • Validates against the expected part number. Halts on mismatch
  • Works with tablet camera, USB barcode reader, or Bluetooth scanner
  • Wrong-part attempts logged for the supervisor's reference
  • Optional enforced step ordering: operators can't skip ahead
Defect, scrap, downtime. Captured at the source

Photo, reason, supervisor. Without leaving the build

When something's off. A casting blemish on the caliper body, a missing fastener in the kit, a downed compressor. The operator hits the flag button on the current step, picks a reason, takes a photo with the tablet, and the unit drops into the supervisor approval queue. The build pauses, the operator gets a new unit to work on, and the supervisor disposes (ship-as-is / rework / scrap) from their floor view. The original photo stays attached through the decision. The auditor sees what the operator saw.

  • In-line flag for defect, scrap, or variance. One tap from the build
  • Photo capture from the tablet camera, attached to the flag
  • Reason picker from an admin-configurable catalog
  • Build pauses, operator gets the next unit, no idle time
  • Supervisor approval queue with three dispositions + reason
  • Downtime start/stop with reason. Feeds the plant-wide pareto
Operator-first design

It works for the operator, not just the boss

The thing classic MES systems get wrong is treating the operator as data capture. Ignite Lean's kiosk shows the operator their own personal queue, their target vs. actual cycle time on the current build, their last five completes for the day, and a streak counter that rewards consistency. Stations stop feeling like surveillance terminals and start feeling like the operator's own bench. Which is the difference between an MES the floor tolerates and an MES the floor actually uses.

  • Personal queue per operator
  • Live target vs. actual cycle time during the build
  • Recent completes for the operator (not just the station)
  • Glove-friendly tap targets (44 × 44 pt minimum, capacitive-friendly)
  • Works on any iPad, Surface, Android tablet. No native app to install
  • Free for operators forever. You only pay for manager seats
