When crashing a schedule to minimize cost, which activities should be crashed first?
Answer: Critical path activities with the lowest crash cost slope
Crashing critical path activities with the lowest crash cost slope first maximizes time reduction per additional dollar spent.
What happens to a near-critical path when fast-tracking consumes all of its available float?
Answer: It becomes a new critical path, creating multiple critical paths
When fast-tracking consumes all float on a near-critical path, that path becomes critical, potentially creating multiple concurrent critical paths.
Which document formally authorizes schedule recovery actions on a construction project?
Answer: A schedule recovery plan or recovery baseline approved through change control
A schedule recovery plan documents the approved recovery actions, revised logic, and any new baseline submitted through the formal change control process.
In schedule compression, 'what-if' scenario analysis is primarily used to:
Answer: Evaluate the impact of potential schedule changes before implementing them
What-if scenario analysis allows schedulers to model and evaluate different compression strategies and their impacts before committing to irreversible changes.
Which of the following is NOT a recognized schedule acceleration technique?
Answer: Expanding the scope of work to add buffer activities
Expanding scope adds more work to be completed and would extend rather than compress the overall project schedule.
When multiple critical paths exist after schedule compression, the scheduler must:
Answer: Monitor and actively manage all critical paths to protect project completion
When multiple critical paths exist, delay on any one of them will delay the project end date, so all must be actively monitored.
The 'time-cost tradeoff curve' in schedule optimization illustrates that:
Answer: After optimal compression points, additional crashing yields diminishing returns and becomes cost-prohibitive
The time-cost tradeoff curve shows that beyond optimal compression points, further duration reduction requires disproportionately large cost increases.
