In a critical path analysis, the shortest path is what drives the completion date for the project.
False;
longest path

False;
late start and late finish dates
Knowing the amount of float allows project managers to know whether a project schedule is flexible.
True
The main disadvantage of crashing is that it lengthens the time needed to finish a project.
False;
advantage; shortens
The technique of fast tracking can result in lengthening the project schedule.
True
Critical chain scheduling assumes that resources multitask and maximizes multitasking.
False;
It assumes that resources do not multitask or at least minimize multitasking.
One of PERT’s main disadvantages is that it does not address the risk associated with duration estimates.
False;
it does
The final process in project time management is developing the schedule.
False;
controlling the schedule
A drawback of the project management software is that it does not have the capacity to calculate the critical path(s) for a project.
False;
it can

controlling the schedule
In project time management, a(n) _____ is an output of controlling the schedule
project management plan update
Which of the following documents is most likely to include planned project start and end dates which serve as the starting points for a detailed schedule?
Project charter
Which of the following is a difference between an activity list and an activity attribute?
An activity attribute provides more schedule-related information about each activity than an activity list.
A(n) _____ on a project is a significant event that normally has no duration.
milestone
In project time management, the main goal of _____ is to ensure that the project team has complete understanding of all the work they must do as part of the project scope so they can start scheduling the work.
defining activities
In project time management, the next step after defining project activities is:
determining their dependencies.
Which of the following types of dependencies are inherent in the nature of work being performed on a project?
Mandatory
____ dependencies are sometimes referred to as soft logic and should be used with care because they may limit later scheduling options.
Discretionary
Which of the following dependencies involve relationships between project and non-project activities?
External
In an AOA network diagram, _____ occur when two or more activities follow a single node.
bursts
A network diagramming technique in which boxes represent activities is known as a(n) _____.
PDM (Precedence Diagramming Method)
AOA network diagrams use only _____ dependencies.
finish-to-start
Which of the following is a relationship in which the “from” activity cannot start until the “to” activity is started?
Start-to-start
Which of the following is true of a finsih-to-finish dependency?
It is a dependency in which the “from” activity must be finished before the “to” activity can be finished.
Which of the following is true of dummy activities?
They show logical relationships between activities.
Which of the following is one of the main outputs of estimating activity resources process?
Project documents update
After working with key stakeholders to define activities and calculate their resources, the next process in project time management is to:
estimate the duration of activities.
In project time management, the ultimate goal of _____ is to provide a basis for monitoring project progress for the time dimension of the project.
developing a schedule
