Demand (units/shift)

Takt time is the drumbeat of production — the shift length divided by demand, the pace each unit must be finished to meet the order. Tasks are grouped into stations so no station's work exceeds takt. The theoretical minimum stations is the total work over takt; balancing efficiency measures how little idle time is left. Higher demand shortens takt and needs more stations.

Governing equation

T_{t} = \frac{28800}{400} = 72.0 s, η = \frac{38}{1 \times 72.0} = 53%

Reading this result: Takt time is 72.0s, so every unit must clear a station within that window; 1 stations suffice here, leaving about 47% idle slack.
