Question 1

Which critical path method (CPM) concept identifies the longest sequence of dependent activities that determines project duration?

Accepted Answer

Critical Path

Answer

The critical path is the longest sequence of tasks that determines the minimum project duration; any delay on it directly delays project completion.

Question 2

A cost controller uses a 'Schedule Variance at Completion (SV%)' trending upward toward zero. This means:

Accepted Answer

The project is recovering its schedule slippage and moving toward on-time completion

Answer

An SV% trending toward zero from a negative position indicates schedule recovery as actual progress catches up to planned progress.

Question 3

What is 'float' (slack) in project scheduling?

Accepted Answer

The amount of time an activity can be delayed without delaying the project's critical path or end date

Answer

Float is schedule flexibility — activities with positive float can be delayed or stretched within that window without impacting overall project completion.

Question 4

In EVM, the To-Complete Performance Index (TCPI) measures:

Accepted Answer

The cost efficiency required on remaining work to meet the BAC or EAC target

Answer

TCPI = (BAC − EV) ÷ (BAC − AC); a TCPI above 1.0 means future work must be done more efficiently than past work to hit the target.

Question 5

A project's CPI is 0.80. What does this mean for the cost controller?

Accepted Answer

For every dollar spent, only $0.80 of budgeted work has been accomplished — the project is over budget

Answer

CPI = EV/AC = 0.80 means cost efficiency is below 1.0, indicating the project is over budget relative to the work accomplished.
