Phoenix Systems manufactures computer chips and is based in Canada. This year the company has begun working with suppliers in other countries, but the suppliers' quality levels have been erratic. Based on what you have read, which of these is the most cost-effective way to combat this problem?

Fire all the suppliers but one, and use the increased amount of work to bargain for a lower cost per chip.

Hire a broker or intermediary in a supplier's country to determine if that country has a supplier capable of keeping quality standards high.

Hire only Canada-based suppliers so Phoenix can take advantage of lower transportation costs and can more closely supervise product creation.

Eliminate all suppliers and create computer chips in house with a specially trained staff.
