In the example used to explain the principle of production levelling (heijunka), the monthly plan was shown on a table like this.

In this table available hours of each day are displayed in column for the whole month of 20 days.
Each hour (cell) one production order can be processed. The table allows a visual management of production planning.

Order box

A Heijunka box is a box whith cells representing a specified duration, based on the very same principle than the table. Here, each cell represents one hour. All production orders are set into the cells, according to scheduling.

The operator of the leading process takes the orders from the cell corresponding to the actual time and processes the orders like scheduling set them up. This very simple system is also very flexible, as rescheduling is easy to do, exchanging orders in cells.
