A few weeks after production started on Spin Master Toys latest product, E-Chargers, an electrically powered model airplane, the operations manager had to deal with a persistent and serious quality problem; up to 30 per cent of the current production of the wings were substandard. He knew he had to do something fast. The company could not afford any more supply problems. This is the third case in a three case series that follows the selection of a manufacturer and the progress of the production of a new product. The accompanying cases are Spin Master Toys (A):Finding a Manufacturer (product 9B01D001) and Spin Master Toys (B): A New E-Chargers Supplier? (product 9B01D002).
