EL Specialty Manufacturing Company makes an artificial leather-like product for the fashion accessory market. The material is made in sheets and has the appearance of a thin rug. Each sheet is 36 inches wide and 100 feet long and is wound into a roll. The quality manager has requested that 100 rolls be inspected. Thirty-eight nonconformances were found.
a. Calculate the nonconformances per unit (NPU) and the throughput yield (TY).
b. If the production process consists of three steps, with step 1 having a TY of 83 percent; step 2, 90 percent; and step 3, 92 percent, what is the rolled throughput yield (RTY), and the proportion nonconforming?
