The heijunka technique works by leveling both the production volume and the product mix. It doesn’t build products according to the actual flow of customer orders, which can swing up and down widely, but takes the total volume of orders in a period and levels them out so the same amount and mix are being made each day. Heijunka is a technique that helps reach the defined takt time and adds value to it.
