RIRA Company makes attachments, such as backhoes and grader and bulldozer blades, for construction equipment. The company uses a job order cost system. Management is concerned about cost performance and evaluates the job cost sheets to learn more about the cost effectiveness of the operations. To facilitate a comparison, the cost sheet for Job 206 (50 backhoe buckets completed in October) was compared with Job 228, which was for 75 backhoe buckets completed in December. The two job cost sheets follow.

Management is concerned with the increase in unit costs over the months from October to December. To understand what has occurred, management interviewed the purchasing manager and quality manager.
Purchasing Manager: Prices have been holding steady for our raw materials during the first half of the year. I found a new supplier for our bulk steel that was willing to offer a better price than we received in the past. I saw these lower steel prices and jumped at them, knowing that a reduction in steel prices would have a very favorable impact on our costs.
Quality Manager: Something happened around mid- year. All of a sudden, we were experiencing problems with respect to the quality of our steel. As a result, we€™ve been having all sorts of problems on the shop floor in our foundry and welding operation.
