PCC Scheduling & Time Management 3

Question 1

Which PERT formula is used to calculate the expected duration of an activity?

Accepted Answer

(O + 4M + P) / 6

Answer

The PERT three-point estimate formula is (Optimistic + 4×Most Likely + Pessimistic) / 6, giving a weighted average.

Question 2

When a project has negative float on the critical path, what does this indicate?

Accepted Answer

The project cannot meet its imposed deadline without corrective action

Answer

Negative float means the project's calculated finish date exceeds the target date, requiring corrective action like crashing or fast tracking.

Question 3

Which scheduling output documents the planned dates for performing schedule activities and the planned dates for meeting schedule milestones?

Accepted Answer

Project schedule

Answer

The project schedule presents the planned start and finish dates for all activities and milestones in a usable format.

Question 4

A lag in a project schedule network diagram represents:

Accepted Answer

A mandatory waiting period between activities

Answer

A lag is a directed delay added to a dependency, forcing a waiting period between the end of one activity and the start of another.

Question 5

During schedule development, which technique uses historical data from similar past projects to estimate activity durations?

Accepted Answer

Analogous estimating

Answer

Analogous estimating uses actual durations from similar previous projects as the basis for estimating current project durations.
