Answer:
27.78%
Step-by-step explanation:
Missing word "The production facility operates strictly eight hours per day. 5 people work daily in the plant."
In the earlier scenario, furniture maker manufactured 77 (72 non defective) pieces per 5 laborers working 8 hours day. Thus, the productivity in terms of units per labor hour is:
= 72 / 5*8
= 72 / 40
= 1.8
Similarly, after the process improvement, the productivity in units per labor hour would be:
= 92 / 5*8
= 92 / 40
= 2.3
Thus, change in productivity would be calculated as:
= (2.3 - 1.8)/1.8
= 0.27777778
= 27.78%
The productivity of non defective parts would increase by 27.78%
