Tom is responsible for ordering hardware for a custom home his company is building. The contractor installing the hardware is scheduled to start in 5 working days, but the hardware is on backorder and will not arrive for another 9 working days. Fortunately, Tom has 10 days of slack; however, he shares this slack with the hardware installer. He will have to let the contactor know that the hardware will be ready 4 days later than expected and that the slack for the installer has been reduced by 4 days. Tom and the installer share 10 days of:

Total slack

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

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
