A Standard Work Chart is a visual document that shows the layout of a workstation or cell, the sequence of operations, the standard work-in-process, and the safety and quality checks. It is one of the three standard work documents (with the Combination Sheet and the Production Capacity Sheet) that together define the standard.
A scaled sketch of the workstation showing machines, tools, materials and the operator's walking path. Numbered steps in the correct sequence. Symbols marking safety-critical steps, quality checks and standard WIP quantities. Cycle time and takt time. The chart is designed to be posted at the workstation so the standard is visible at all times.
Written procedures describe the work. The standard work chart shows the work. Combined, they make the standard concrete, visual and easy to follow, even for a new operator. Leaders can also use the chart during Gemba walks to compare what is happening against what should be happening, and to coach when the two diverge.
The chart is not decoration. It is updated every time the standard changes, after a Kaizen event, after a Poka-Yoke installation, after a rebalance. An outdated chart is worse than no chart because it teaches an obsolete method. Ownership must be explicit: someone is responsible for keeping every chart current.
The Standard Work Chart makes standard work visible on the shop floor where the work happens. It is a small document with a large role in sustaining stable, repeatable operations and in creating the baseline from which every Kaizen improves.
