# Standardized Work Chart

**URL:** https://kaizumi.com/dictionary/standardized-work-chart

**Description:** A Standardized Work Chart (SWC) is a top-down diagram of a work area showing the operator walking path, work sequence, quality checks, and safety points for a standardized cycle.

## Definition

The Standardized Work Chart (SWC) is Form 3 of the three core standardized work documents in the Toyota Production System. It is a spatial, top-down diagram of a work cell or station that shows the operator's walking path, the sequence of operations, the location of each machine or work point, and the positions where quality checks and safety-critical steps occur. Alongside the diagram, the SWC records the takt time, cycle time, and standard work-in-process for the cycle. Where the Standardized Work Combination Table shows the work in time, the SWC shows it in space — and together they define how a cycle should be performed.

## Examples

### Manufacturing

> A machining cell posted an SWC at the entrance showing the operator's figure-eight walking path across three machines, each loading step numbered in sequence. Red dots marked two in-process quality checks, a yellow triangle flagged the overhead crane interaction as a safety-critical step. New operators could learn the cycle from the chart in minutes.

### Healthcare

> A surgical prep team created an SWC for the pre-op room layout. The diagram showed the verification sequence (patient ID, consent, site marking, medication check), the walking path between the patient, the anesthesia station, and the instrument tray, and the safety-critical pauses for the surgical time-out. The chart became the visual standard for preventing wrong-site surgery.

### Administrative

> A mortgage underwriting team built an SWC-style diagram of their workstation and paper-flow: inbox, screen, document printer, file cabinet. Mapping the movement revealed a 40-foot-per-file walking loop, eliminated by relocating the printer and re-sequencing the steps so the file moved once instead of three times.

## Key Points

- Shows work in space, complementing the SWCT which shows work in time
- Makes the operator's walking path explicit, exposing unnecessary motion
- Flags quality checks and safety-critical steps visually at their physical location
- Posted at the line so operators and leaders share the same standard

## Common Misconceptions

**The SWC is a facility floor plan.** A floor plan shows what is where; an SWC shows what is done in what order, where. The operator path and step sequence are the point, not the geometry.

**The SWC is only for manufacturing cells.** The spatial-standard-work logic applies anywhere a person moves between resources to complete a repeating task — operating rooms, kitchens, labs, warehouses, offices.

## Try It

Build your own right here. Map the work area, trace the operator walking path, mark quality and safety points, and export a print-ready chart. (Also available as a [standalone tool](/tools/swc).)
