Question

1. "Step X of a project has been budgted for 600. It is 0% complete. You have spent 400 so far. You had to order steel and had to make an advance payment. Are you overbudget or underbudget. If you are underbudget, indicate the amount as a negative number. If you are overbudget, indicate the amount as a positive number (no plus)."

2. Step X normally takes 4 weeks and $800. You can crash it to 2 weeks and it cost $ 1200. What is the weekly crash cost? If this impossible, enter -999.

3. Step X: EST = 8, LST = 12, LST = 9, LFT = 12. What is slack? (enter -999 for impossible nodes

Answer 1

1. Since 0% is complete, nothing should have been spent.

However, actual expenditure is 400

Therefore, we are overbudget by = 400 – 0 = 400

1. Weekly crash cost

= ( Crash cost – Normal cost )/ ( Normal duration – Crash duration )

= ( $1200 - $800) / ( 4 – 2 )

= $400/2

= $200

1. It is confusing to answer the question because Late Start time ( LST) at one place is mentioned as 12 and another place is mentioned as 9. There has to be unique value for LST.

However if we ignore above,

We can say that Slack = LST – EST = 12 – 8 = 4
