PM - Lesson 6

The shortest time necessary to complete all of the activities in a network is called the:

• Activity duration length

• Critical path

• Maximum slack path

• Compression path

Which of the following cannot be identified after performing a forward and backward pass?

• Dummy activities

• Slack time

• Critical path activities

• How much overtime is scheduled

Which of the following is not a commonly used technique for schedule compression?

• Resource reduction

• Reducing scope

• Fast-tracking activities

• Use of overtime

A network-based schedule has four paths, namely 7, 8, 9, and 10 weeks. If the 10-week path is compressed to 8 weeks, then:

• We now have two critical paths.

• The 9-week path is now the critical path.

• Only the 7-week path has slack.

• Not enough information is provided to make a determination.

The major disadvantage of using bar charts to manage a project is that bar charts:

• Do not show dependencies between activities

• Are ineffective for projects under one year in length

• Are ineffective for projects under $1 million in size

• Do not identify start and end dates of a schedule

The first step in the development of a schedule is a:

• Listing of the activities

• Determination of dependencies

• Calculation of effort

• Calculation of durations

Reducing the peaks and valleys in manpower assignments in order to obtain a relatively smooth manpower curve is called:

• Manpower allocation

• Manpower leveling

• Resource allocation

• Resource commitment planning

Activities with no time duration are called:

• Reserve activities

• Dummy activities

• Zero slack activities

• Supervision activities

Optimistic, pessimistic, and most likely activity times are associated with:

• PERT

• GERT

• PDM

• ADM

The most common “constraint” or relationship in a precedence network is:

• Start-to-start

• Start-to-finish

• Finish-to-start

• Finish-to-finish
