| Question | Answer |
|---|---|
| Preceding activities are those that must occur before others can be done. | True |
| A backward pass is performed when it is necessary to undo some work that has been performed in order to complete it properly. | False |
| Float is always measured in exactly the same way as slack. | True |
| Burst activities are those with two or more successor activities. | True |
| In assigning a value for the most pessimistic (b) duration, the project manager should estimate the duration of the activity to have a 99% likelihood that it will take b or less amount of time. | True |
| The late start time should be calculated using a forward pass through the network. | False |
| Laddering is a technique that allows the project manager to redraw the network to more closely sequence project subtasks to make the overall network sequence more efficient. | True |
| At a burst point in a backward pass, the largest succeeding late start becomes the late finish for that node. | False |
| Activity float is the difference between the late finish and early finish for the activity in question. | True |
| The term ordered activity means: | tasks must either precede or follow other tasks in project planning and management. |
| A sequence of activities defined by the project network logic is a(n): | Path |
| One of the defining points of a network, a junction point joined to some or all of the others by dependency lines, is called a(n): | Node |
| These can be located by doing a backward pass through a network. | Burst Activities |
| An activity with two or more immediate predecessors is a(n): | Merge Activity |
| The least amount of float is found: | on the critical path |
| The variance of an activity is given by: | [1/6(b-a)] ^2 |
| An activity has an optimistic time estimate of 15 days, a most likely estimate of 24 days, and a pessimistic estimate of 40 days. What is the expected duration of the activity? | less than 26 days but greater than or equal to 25 days |
| An activity has an optimistic time estimate of 7 days, a most likely estimate of 12 days, and a pessimistic estimate of 20 days. What is the expected standard deviation of the activity? | between 2 and 3 days |
| The amount of time an activity may be delayed from its early start without delaying the finish of the project is the: | Float |
| Negative float exists when a project's critical path has been completed more quickly than anticipated. | False |
