CAPM Project Scheduling & Critical Path 2

Question 1

A project has activities A→C→E on one path (durations 3,5,4) and A→B→D→E on another (durations 3,2,6,4). Which path is critical?

Accepted Answer

A→B→D→E with duration 15

Answer

A→B→D→E totals 3+2+6+4=15 days, which is longer than A→C→E at 3+5+4=12 days, making it the critical path.

Question 2

What does a negative float (slack) value on an activity indicate?

Accepted Answer

The schedule has a constraint violation or the project is behind schedule

Answer

Negative float means the activity's late finish is earlier than its early finish, indicating a schedule constraint violation or delay.

Question 3

Which scheduling technique uses three time estimates (optimistic, pessimistic, most likely) to calculate expected activity durations?

Accepted Answer

Program Evaluation and Review Technique (PERT)

Answer

PERT uses three-point estimates with the formula (O + 4M + P) / 6 to calculate expected duration under uncertainty.

Question 4

In a Precedence Diagramming Method (PDM) network, which relationship type means successor cannot start until predecessor finishes?

Accepted Answer

Finish-to-Start (FS)

Answer

Finish-to-Start (FS) is the most common dependency type, where the successor activity cannot begin until the predecessor is complete.

Question 5

A project manager applies fast tracking to compress the schedule. What is a primary risk of this technique?

Accepted Answer

Rework because activities that were meant to be sequential now overlap

Answer

Fast tracking overlaps activities that were originally planned sequentially, which can cause rework if later work depends on outputs from earlier work that isn't complete.
