What a visual factory looks like
- Status at a glance: andon lights on machines, hour-by-hour boards, tier boards with red and green measures.
- A place for everything: marked floor locations, shadow boards for tools, labelled shelves and containers.
- Standards where they are used: standard work, one-point lessons and SOP steps posted at the station.
- Flow made visible: kanban cards and squares, FIFO lanes, work-in-progress limits.
- Safety made visible: walkways, exclusion zones, PPE requirements, permit boards.
- Problems made visible: open actions, escalations and audit results on the area's board.
Why it matters
Visual controls turn the whole workforce into a problem-detection system. A missing tool, a full red lane, a red andon light or a red measure is seen by anyone passing, not only by the person responsible. Leaders on a gemba walk read the factory instead of asking for a report.
Building a visual factory
- Start with 5S so there is a standard to make visible.
- Decide what each area needs to see: the few measures, the standards, the status signals.
- Make normal and abnormal obvious: colour, position, size. If it takes explanation, it is not visual.
- Put the board where the team meets and run the daily huddle from it.
- Audit the visuals like any other standard; faded tape and stale boards undo the effect.
Physical and digital
Physical visuals, markings, shadow boards, lights, are irreplaceable at the workstation. Digital displays add live measures, actions that move between tiers and history, and keep remote leaders in the picture. The two should show the same picture.
