a. 33.333 Labels per minute
b. 42.5 Labels per minute. The second worker is more productive. He can create 42.5 labels per minute where the first one can only create 33.3 labels a minute.
2. Howard Plastics produces plastic containers for use in the food packaging industry. Last year its average monthly production included 20,000 containers produced using one shift five days a week with an eight-hour-a-day operation. Of the items produced 15 percent were deemed defective. Recently, Howard Plastics has implemented new production methods and a new quality improvement program. Its monthly production has increased to 25,000 containers with 9 percent defective.
(a) Compute productivity ratios for the old and new production system.
a. 8*5 = 40 20,000 – 3000 = 17000/160 = 106.25 good parts per hour
b. 25,000 – 2250 = 22,750/160 = 142.1875 good parts per hour
c. (22750-17000)/ 17000 = 34% increase
(b) Compare the changes in productivity between the two production systems.
a. The machine that produced 25,000 containers is better and is more efficient.
