The Answer would be C (7000 USD)
Reason

If you crash activity A and E , you will earn

(10-8) +(9-7) = 4 weeks

 

and the budget to do so would be 

 

(4000-6000) + (14000-19000) = - 7000

Which means one would have to spend 7000 USD more to crash this schedule 

 

Does anyone else has a different answer????

 

Hope that helps,

Hello Valentin,

 

Good to see such a good example.

- We need to understand the importance of baseline. What ever might be the reason the team wants to compress the schedule. To compress the schedule we have 2 techniques. fast tracking and crashing. Crashing is done by adding additional resources. That means additional cost.

 

As per the requirements, we need to crash 4 weeks.

Look at the options over there. You can crash with task F alone. But the additional cost would be $18,000.

Take activities D and E - the additional cost will be $6000 but you can crash only 3 weeks.

Other options E+A=4 weeks $7000, E+C = 4 weeks = $9000.

 

Consider option A+C you can reduce the schedule by 4 weeks and can additional cost would be $6000 only.

This is the lowest possible option.

 

Thanks

The answer should be B ie 6000 USD

 

Crash activity A and C

 

ie

 

(10-8)+(14-12) =4 weeks

 

cost wise (4000-6000)+(22000-26000)

(-2000) + (-4000)= - 6000

So least cost to crash is 6000 USD.

 

If any body disagree please reply back

 

Thanks
