Answer:
Total slack
Step-by-step explanation:
Total slack is defines as the time that tasks are delayed which will eventually affect the finishing date of a project.
Total slack can be either positive or negative. Positive slack is when delay in tasks do not affect project finish date, and negative slack are delays that affect project finish date.
Total slack is calculated as difference between smaller value of late finish and early finish.
Tom shares 4 days of his slack with the contractor.
So he has 10- 4 = 6 days slack
The total slack is 6 + 4= 10 days
In this scenario the difference between late start and early start is 9 - 5= 4 days
