  • Eliminate the need for the three stagers (Reinvest them into value added jobs).

Approach:

  • Charter a raw materials replenishment team.

  • Provide Kanban Pull System Training.

  • Calculate demand for each item number and establish standard Kanban quantities and containers.

  • Set up Kanban Inventory Locations at the point of use on each assembly line.

  • Set up blanket orders for each item number with suppliers.

  • Right-size the inventory level for each item by allowing the assembly lines to pull excess materials down to the new maximum inventory level.

  • Begin replenishing to point of use using the new Kanban Pull System.

  • Shut down incoming warehouse.

  • Reinvest three stagers into value added positions.

  • Present results to the management team.
