Yamazumi Charts


A Yamazumi chart is a stacked bar chart that shows the balance of cycle time workloads between a number of operators typically in an assembly line or work cell. The Yamazumi chart can be either for a single product or multi product assembly line.

Yamazumi is a Japanese word that literally means to stack up.

Toyota uses Yamazumi work balance charts to visually present the work content of a series of tasks and facilitate work balancing and the isolation and elimination of non value added work content.

Video Timer Pro automatically embeds videos in each activity chip when measuring the work content. Clicking on the chip instantly replays the content to explore improvement opportunities or for operator training.

A single click in Timer Pro will send the entire Yamazumi balance chart to Excel (shown below). The system automatically sizes the work elements in proportion to the work content. Additionally, it embeds video snippets in the Excel sheet. Charts can be printed from Excel in any size – some companies print them out over 3 feet tall for worker and management review.
