Value Steam Mapping Data Set TWI Industries TWI Industries produces several components for tractors. This case concems one product family - Steering Arms - which are produced in many configurations. TWI's customers for this product family are both originalequipment tractor builders and the aftermarket repair business. Because of the wide variety of product configurations and the fact that customer configuration requirements vary from order to order, steering arms are a "make-to-order" business. It currently takes a customer order 27 days to get through TWT's production processes. This long lead time and a significant order backlog have prompted TWI to quote a 60-day lead time to customers. However, TWI's customers cannot accurately predict their size requirements more than 2 weeks out, and thus they make adjustments to their orders 2 weeks before shipment. These order adjustments lead to order expediting on the shop floor at TWI. Although TWI Production Control releases customer orders to production roughly in the order that they are received, orders are batched by product configuration on the shop floor to reduce the number of time-consuming changeovers. This also creates a need for order expediting. The Product - A steering arm is a metal rod with a forged fitting welded to each end. - TWI's steering arms are available in 20 different lengths, 2 diameters, and with 3 different types of end fittings. (Each end of the steering arm can have a different fitting.) This means there are 240 different steering arm part numbers that TWI supplies.
