Project Management

Which of the following must hold for an activity on the critical path in a PERT network?

• a) Slack = 0

• a) ES=LS

• a) EF=LF

• a) All of these

A project can have more than one critical path.

• True

• False

A critical path must go from “start” node to “finish” node

• True

• False

The performance times (durations) of the “start” node and “finish” node are

• 0

• To be determined by manager

• Usually different, but at least 1 working day

One day delay of a task on the critical path would cause one day delay of the whole project

• True

• False

We should go ___________ when calculating latest times, LS and LF

• Forward

• Backward

Suppose activity H’s immediate predecessors are D and G. EF=8 for G. What is ES for H?

• 8

• 10

• 12

• Not enough information is provided in here

Suppose the common immediate predecessor of Q and R is P. LS=8 for Q. LS=12 for R. What is the LF for activity P?

• 8

• 10

• 12

• Not enough information provided, cannot be determined

Which is correct?

• The critical path identified at the beginning of a project will never change in the progress of the project

• The critical path identified at the beginning of a project may change if some activities’ actual completion times are not as expected.
