Answer:
a. Labor productivity is calculated as: Labor productivity = Total Yards Installed / Total Crew Size
Hence, the labor productivity for each week is;
Week 1 = 97 / 4 = 24.25
Week 2 = 71 / 3 = 23.67
Week 3 = 98 / 4 = 24.5
Week 4 = 54 / 2 = 27
Week 5 = 63 / 3 = 21
Week 6 = 52 / 2 = 26
b. A crew of size 2 works the best as they generate the highest labor productivity of 27. The crew with highest number generate a labor productivity of 24.5
