A point beyond which the project duration cannot be reduced irrespective of the increase in direct cost is known as
- Anormal duration
- Boptimum duration
- Cpessimistic duration
- Dcrash durationCorrect
Solution
Concept
Crash time
Step-by-step solution
1. The shortest possible duration, no matter how much extra direct cost is spent, is the crash duration.
Explanation
Time-cost trade-off analysis reduces the duration by spending more on direct cost up to the crash point, beyond which no further reduction is possible.
Why the other options are wrong
Normal duration is the least-cost duration, optimum duration is the least total-cost duration, and pessimistic duration is a PERT estimate.
Shortcut
Crash = fastest possible.
Common mistake
Choosing optimum duration.
Correct answer: D) crash duration
