100% VERIFIED
T/F: At the beginning of every project, it is possible to estimate the durations for all
activities with a high level of confidence regarding their accuracy. - ANSWER False
Having the person who will be responsible for performing a specific activity estimate the
duration for that activity _____ from that person and _____ that may be introduced by
having one person estimate the durations for all of the activities - ANSWER generates a
commitment, avoids any bias
T/F: A consistent time base, such as hours or days or weeks, should be used for all the
estimated durations of activities in a network diagram - ANSWER True
If an organization or subcontractor has performed similar projects in the past and has
kept records of how long specific activities actually took, these historical data: - ANSWER
can be used as a guide in estimating the durations of similar activities for future projects
If an organization or subcontractor has performed similar projects in the past and has
kept records of how long specific activities actually took, these historical data - ANSWER
can be used as a guide in estimating the durations of similar activities for future projects.
In order to establish a basis from which to calculate a schedule using the estimated
durations for the activities, it is necessary to - ANSWER select an estimated start time
and a required completion time for the overall project.
, T/F: Padding estimates with the vision of becoming a hero when the activities are
completed in less time than estimated is not a good practice. - ANSWER True
When estimating durations for activites with a high degree of uncertainty, one approach
is to provide 3 estimates to help calculate your overall estimate... these 3 estimates are...
- ANSWER an optimistic estimate, a pessimistic estimate, and a most likely estimate.
Earliest start time (ES) is the earliest time at which a specific activity can begin - ANSWER
calculated on the basis of the project estimated start time and the estimated durations of
preceding activities.
Earliest finish time (EF) is the earliest time by which a specific activity can be completed,
calculated - ANSWER by adding the activity's estimated duration to the activity's earliest
start time: EF = ES + Estimated Duration.
Latest start time (LS) is the latest time by which a specific activity must be - ANSWER
started in order for the entire project to be finished by its required completion time.
Latest start time is calculated by - ANSWER subtracting the activity's estimated duration
from the activity's latest finish time: LS = LF- Estimated Duration
Latest finish time (LF) is the latest time by which a specific activity must be - ANSWER
completed in order for the entire project to be finished by its required completion time
