Chapter 6.2
If, for some reason, the project must be expedited to meet an earlier date, which of the following actions would the project manager take first?
Check to see which activities are on the critical path.
Which of the following correctly calculates the early finish for an activity?
ES + DUR
Which of the following will correctly calculate the total slack in an activity?
Either LS - ES or LF - EF
________ activities must be completed immediately before a particular activity.
Predecessor
________ activities are to be completed immediately following a particular activity.
Successor
Which of the following is true about hammock activities?
They are used to identify the use of fixed resources or costs over a segment of a project.
If a project has more than one activity that can begin when the project is to start, a common start node should be used to indicate a clear project beginning on the network. Without a common start node, each path is a
dangler path.
The backward pass in project network calculations determines all of the following EXCEPT
earliest time an activity can finish.
The assumption that all immediately preceding activities must be 100% complete is too restrictive in some situations. When an activity is broken down into smaller segments in order to start the succeeding activity sooner, this is called
laddering.
The minimum amount of time a dependent activity must be delayed to begin or end is referred to as
lag.
The likelihood the original critical path(s) will change once the project is initiated is referred to as
sensitivity.
The forward pass in project network calculations determines all of the following EXCEPT
the critical path.
A purchasing agent is responsible for ordering hardware for a custom home his company is building. The contractor installing the hardware is scheduled to start in 5 working days, but the hardware is on backorder and will not arrive for another 9 working days. Fortunately, the purchasing agent has 10 days of slack; however, he shares this slack with the hardware installer. He will have to let the contractor know that the hardware will be ready 4 days later than expected and that the slack for the installer has been reduced by 4 days. The purchasing agent and the installer share 10 days of
total slack.
The amount of time an activity can be delayed and yet not delay the project is termed
total slack.
Which of the following correctly calculates the late start for an activity?
LF - DUR
