CST Schedule Compression & Acceleration Techniques 2

Question 1

When crashing a schedule to minimize cost, which activities should be crashed first?

Accepted Answer

Critical path activities with the lowest crash cost slope

Answer

Activities with the most total float

Answer

Activities with the largest resource allocation

Answer

Non-critical activities with the longest duration

Question 2

What happens to a near-critical path when fast-tracking consumes all of its available float?

Accepted Answer

It becomes a new critical path, creating multiple critical paths

Answer

The project duration automatically increases

Answer

Float increases on all other network paths

Answer

The original critical path is automatically eliminated

Question 3

Which document formally authorizes schedule recovery actions on a construction project?

Accepted Answer

A schedule recovery plan or recovery baseline approved through change control

Answer

The original project charter

Answer

The original project schedule baseline

Answer

The resource-loaded histogram

Question 4

In schedule compression, 'what-if' scenario analysis is primarily used to:

Accepted Answer

Evaluate the impact of potential schedule changes before implementing them

Answer

Determine the actual cost of work completed to date

Answer

Calculate the earned value of in-progress activities

Answer

Establish the original project baseline for contract purposes

Question 5

Which of the following is NOT a recognized schedule acceleration technique?

Accepted Answer

Expanding the scope of work to add buffer activities

Answer

Authorizing overtime for critical path crews

Answer

Resequencing activities to allow parallel execution

Answer

Accelerating material procurement to reduce lead time

Question 6

When multiple critical paths exist after schedule compression, the scheduler must:

Accepted Answer

Monitor and actively manage all critical paths to protect project completion

Answer

Monitor only the original critical path identified at baseline

Answer

Remove constraints from the least important critical path

Answer

Reduce resources on near-critical paths to simplify monitoring

Question 7

The 'time-cost tradeoff curve' in schedule optimization illustrates that:

Accepted Answer

After optimal compression points, additional crashing yields diminishing returns and becomes cost-prohibitive

Answer

Cost always decreases linearly as duration is reduced

Answer

Resource leveling and crashing produce identical cost outcomes

Answer

Earned value always improves when schedule compression is applied
