Heijunka

Heijunka is a lean tool used for minimizing the overburden & unevenness in a production process.

With the implementation of Heijunka the batch production can be stopped and can start processing the orders as per the customer requirement. By this the inventory costs will come down as there will be less volume of goods when the customer demand is low.

Using Heijunka when the varying customer demands are met the process and the team will be protected from getting overburden. Heijunka will help to produce & deliver the products to the customer at a balanced rate so that the variations are handled as per the average demand which is achieved by the following ways

  • Levelling by volume
  • Levelling by type

Levelling by Volume

Processing in batches has to be stopped and continuous flow of work is to be implemented to reduce the inventory costs. Lean emphasises that production to be continued only when there are orders from the customers.

The average volumes of all orders received are processed to level out the production.

Ex: If the average customer demand is 30 orders per week and the varying daily demand is Mon; 7, Tue; 10, Wed; 5 ….etc. Using Heijunka we can level out production by quantity, i.e.  average 5 orders per day are to be processed for levelling the volume.  By this the process runs smoothly without overburden when there are fluctuations during the week.

Levelling by Type

When you are having a family of products and want to level the production by each type based on the average demand of the product Heijunka can be used to organize the work smoothly.

Example ; If you have 7 orders per week for product A, 4 orders per week for product B, 9 orders per week for product C and 5 products per week for product D, the production can be levelled to your capacity to produce 25 numbers in total per week. However you can use Heijunka for levelling the production by each product type.
