Wendy is the project manager for the NHQ project. She is working with her project to begin
creating the project duration estimate. Her organization is in weak matrix and several of the project
team members are scheduled to complete work on other projects. What input will most likely be of
the biggest assistance as Wendy and the project team begin creating the duration estimate for this
project?

A.
Project charter

B.
Project scope statement

C.
Project communications management plan

D.
Resource calendar

Explanation:
The resource calendar is needed because it will help Wendy and the project team to determine
when the project team resources will be available. The availability of the project resources can
affect the overall duration of the project. A resource calendar is used to make sure that work
resources (people and equipment) are scheduled only when they are available for work. They
affect a specific resource or category of resources. By default, the working time settings in the
resource calendar are the same as in the project calendar. However, a user can customize the
resource calendar to show individual schedule information, such as vacations, leaves of absence,
or equipment maintenance time.
Answer option B is incorrect. The project scope statement is an input to the estimate activity
duration estimate, but it is not the best choice for this question.
Answer option C is incorrect. The project communications management plan is not an input to the
estimate activity duration process.
Answer option A is incorrect. The project charter is not an input to the estimate activity duration
process.
