Total activity duration = 16.33 days = 17 days
Critical path is (A,C,F,G,I)
Z probability
= (34-16.3)/(0.25+0.11+0.25+0+0.028)
=27.74
If Z>5 so probabilityis 0.75/75%

2. Q2:
Productivity = Units produced/labor hours used
Current Labor Productivity (when no buyer) = Output / Input
So,
Output = 300 crates
Input = Material required + labor hours
One log requires 3 labor hours; therefore 200 logs require 600 labor hour.
Current Labor Productivity
= 300 crates / (200 logs * 3 hours/ log)
= 300 / 600 = 0.5 crates per labor hour
New Output = 160 crates
Increase in labor hours = 8
Labor Productivity:
= 160 crates / (120 logs * 3 hours/ log) + 8 hours
= 160 / 368
= 0.4348 crates per labor hour
Difference:
(0.43 – 0.5) / 0.5 * 100
= -14%
The productivity with professional buyer would decrease by 14%
