which one?

You are the project manager for your organization. You are working with your virtual team to
create activity duration estimates for your current project. This virtual team is comprised of team
members from around the world. Much of this process will be completed by geographical locations
though some conferences will require all the team members to participate and to coordinate the
activities that will interact between the different sites. The project manager must consider all of the
following when creating the activity duration estimates except for which one?

A.
Project calendar

B.
Critical path

C.
Resource calendar

D.
Time zone differences

Explanation:
When it comes to creating the project’s activity duration estimating, the critical path is not yet a
concern. The critical path will be determined by the duration of the project activities and the
sequencing of the project events. A critical path is the sequence of project activities, which add up
to the longest overall duration. This determines the shortest time possible to complete the project.
Any delay of an activity on the critical path directly impacts the planned project completion date
(i.e. there is no float on the critical path). A project can have several, parallel, near critical paths.
An additional parallel path through the network with the total durations shorter than the critical path

is called a sub-critical or non-critical path. These results allow managers to prioritize activities for
the effective management of project completion, and to shorten the planned critical path of a
project by pruning critical path activities, by “fast tracking” (i.e., performing more activities in
parallel), and/or by “crashing the critical path” (i.e., shortening the durations of critical path
activities by adding resources).
Answer option C is incorrect. The resource calendar must be considered for the availability of the
project resource.
Answer option A is incorrect. The project calendar must be considered to determine when the
project work is allowed to take place in the different sites.
Answer option D is incorrect. Time zone differences must be considered for communication
demands and coordination of events between the geographical sites.
