2. Which of the following is true about the duration estimates?
A. The duration estimates may be progressively elaborated.
B. The activity durations are often estimated before estimating activity resources.
C. Resource utilization could be helpful in estimating activity durations.
D. The duration estimate helps to define the required resource for each project activity.
HINT: Note that we often return to planning processes as we learn and integrate new
information.
QUESTION:
3. The correct answer is A.
The Estimate Activity Durations process involves estimating the number of work periods needed to
complete individual activities. These duration estimates depend on the estimated resources required to
complete the work. The Estimate Activity Resource process, in turn, depends on the activity list, attributes,
assumptions, and cost estimates that are produced in the Define Activities and Estimate Costs processes.
Indeed, the planning processes for several knowledge areas are interdependent.
At the beginning of the project planning with limited information about the project, estimates are likely to
be less accurate and less reliable. Thus, the estimates should be iteratively developed as more accurate
and up-to-date information is available. The duration estimates are documented as activity attributes,
usually associated with the activity list as an output of this process, and an input to the next process,
which is Develop Schedule.
