Blaine Reid, purchasing manager at Hewitt Dental, in Sacramento, California, was reviewing the purchasing strategy for the company's adaptive matching composite (AMC) product line. Hewitt Dental currently used two sources for this product line, but Blaine was considering changing to a single supplier with the expectation that he could secure a cost reduction. Blaine needed to evaluate whether single sourcing represented the best approach for the AMC product line, and if so, which supplier should be selected. It was Monday, January 25, and Blaine was expected to make his recommendation during the commodity review committee meeting at end of the week
