## Definition

A shadow board is a visual control tool where each item's designated location is marked by an outline or "shadow" of the item, typically painted on a board, cabinet, or wall. When tools are in place, they cover their shadows; when removed, the empty shadow immediately reveals what's missing and where it belongs. Shadow boards are a classic application of seiton (set in order) from 5S, making correct storage obvious and missing items impossible to overlook. They reduce search time, prevent loss, and simplify returning items to correct locations.

## Examples

### Manufacturing

> A maintenance shadow board holds frequently used tools. Each tool's outline is painted on the board in contrasting color. At shift end, a glance reveals any missing tools. New technicians immediately know where each tool belongs without asking or guessing.

### Healthcare

> A crash cart uses shadow board principles—each item has a designated, labeled location with outlines. Missing items are immediately obvious during checks. After use, restocking is quick and error-free because locations are unambiguous.

### Administrative

> An office supply area uses shadow board concepts—each type of supply has a marked location with label and outline. Missing items and low inventory are visible at a glance. Anyone can restock correctly without instructions.

## Key Points

- Shadow boards make missing items immediately obvious without counting or inspection
- They eliminate "where does this go?" questions—the outline shows exactly
- Shadow boards reduce time searching for tools and increase accountability
- They work for any items that have designated locations

## Common Misconceptions

**Shadow boards only work for tools.** The principle—showing designated locations visually—applies to supplies, equipment, documents, or any items that should have a "home." The concept transcends physical tools.

**Shadow boards are permanent and inflexible.** Good shadow boards can be updated as needs change. The investment in creating them should be balanced against need for flexibility.

## Try It

A shadow board answers two specific items in the audit below: whether visual indicators show where items belong, and whether a missing item is immediately obvious. Both sit in the Set in Order section. Score one real area against those two before you build anything. If storage locations are not labeled yet, a shadow board is premature. That gap shows up one item earlier in the same section.
