A factory produced a new type of refrigerator designed to use less electricity. The machine was manufactured and sold to the public at Target, Wal-Mart, and K-Mart. After several months, reports showed that this refrigerator was not working correctly. 
Which choice below is the most likely cause?

• The proper cost analysis was not performed.
• The designers did not test other types of machines.
• They did not rigorously test and modify the prototype
