1. (TCO 1) A company has found that introducing one additional worker enables a process improvement that reduces processing time for each unit so that output is increased by 25% with less material. Under the old process, five workers could produce 60 units per hour. Labor costs are $12/hour, and material input was previously $16/unit. For the new process, material is now $10/unit. Overhead is charged at 1.6 times direct labor cost. Finished units sell for $31 each. What increase in productivity is associated with the process improvement? (Points : 30)

 

Factor                   Old System                         New System

Output                       60                                     60(1.25) = 75

# of workers             5                                              6

Worker cost           $12/hr                                                   $12/hr

Material                                 $16/unit                                                 $10/unit

Overhead                1.6(labor cost)                               1.6(labor cost)
