Project Management: Ch 5 quiz Qs
Total slack for the project is the difference between?
EF time of the last activity and the project required completion time
The project control process must occur regularly throughout the project and include all of the following except?
Having a single inspection of the project's deliverables at the end of the project
The _____ and _____ times are determined by working through the network diagram from the end of the project to the beginning of the project.
LF, LS
The total completion time is 25 days. Task A is planned to take seven days. Task B is planned to take five days. Task C is planned to take eight days. The tasks have a sequential relationship. How much slack does the project have?
Positive 5 days slack
Negative slack indicated a lack of slack over the entire project and the amount of time?
an activity must be accelerated to complete the project by the required completion time
Earliest finish time (EF) is the earliest time by which a specific activity can be completed, calculated?
by adding the activity's estimated duration to the activity's earliest start time: EF = ES + Estimated Duration
The longest path of activities from the beginning to the end of a project is called the _____ path?
critical
Calculate the latest start for Task B if its predecessor, Task A, finished on day 3, Task E, has a latest start day of day 7, and the duration of Task B id 2 days.
day 5
Calculate the earliest finish for Task D if one of its predecessors, Task A, finishes on day 3, its other predecessor, Task C, finishes on day 4, and the duration of Task D is 2 days.
day 6
Calculate the latest finish for Task B if its predecessor, Task A finishes on day 3, its succeeding activity, Task E, has a latest start of day 7, and the duration of Task B is 2 days.
day 7
Calculate the latest start for Task D if one of its successors, Task F, has a latest start on day 9, its other successor, Task E, has a latest start time on day 10, and the duration of Task D is 2 days.
day 7
Total slack is sometimes called?
float
The actual finish time of an activity?
has a ripple effect in the project and may alter the remaining activities' earliest start and finish times
When estimating the types and quantities of resources required for each specific activity, it is valuable to involve a person who?
has expertise or experience with the activity to help make the estimate
If the project is ahead of schedule, then concentrated efforts should be made to?
keep it ahead of schedule
Latest start time is calculated by?
subtracting the activity's estimated duration from the activity's latest finish time: LS = LF - Estimated Duration
As the project progresses, the actual finish times (AFs) of completed activities will determine?
the earliest start and earliest finish times for the remaining activities in the network diagram, as well as the total slack
The estimated duration for each activity must be the total time which equals?
the time for the work to be done plus any associate waiting time
If _______ is positive, it represents the maximum amount of time that the activities on a particular path can be delayed without jeopardizing completion of the project by its required completion time.
total slack
The ES and EF times are determined by calculating forward, that is, by?
working though the network diagram from the beginning of the project to the end of the project.
