Chapter 6
After working with key stakeholders to define activities and calculate their resources, what is the next process in project schedule management?
Determine their dependencies
In project schedule management, which process involves analyzing activity sequences, activity resource estimates, and activity duration estimates to create the project schedule?
Developing the schedule
Which dependencies are sometimes referred to as soft logic and should be used with care because they may limit later scheduling options?
Discretionary
A backward pass through the network diagram determines the early start and early finish dates for each activity.
False
In a network diagram, it is mandatory for every item on the WBS to be shown instead of only those activities with dependencies.
False
In project schedule management, the next step after sequencing activities is to define these activities.
False
In project schedule management, the primary output of defining activities is a schedule management plan.
False
Milestones are easy to achieve and are always achieved through one main activity.
False
One of PERT's main disadvantages is that it does not address the risk associated with duration estimates.
False
Start-to-finish relationships are the most frequently used dependencies between activities.
False
The arrows in a network diagram represent missed milestones in a project.
False
The main disadvantage of crashing is that it lengthens the time needed to finish a project.
False
Which technique involves doing activities in parallel that one would normally do in sequence?
Fast tracking
How does critical chain scheduling protect tasks on the critical chain from being delayed?
Feeding buffers
What is the latest possible time an activity might begin without delaying the project finish date?
Late start date
The critical path is the _____ path through a network diagram, and it represents the _____ amount of slack or float.
Longest; shortest
What is an accurate difference between the Program Evaluation and Review Technique (PERT) and critical path method (CPM)?
PERT uses different duration estimates whereas CPM uses one specific duration estimate.
What is the first process involved in project schedule management?
Planning schedule management
Which document is most likely to include planned project start and end dates which serve as the starting points for a detailed schedule?
Project charter
Which is true of dummy activities?
They show logical relationships between activities.
A dependency pertains to the sequencing of project activities or tasks.
True
Network diagrams are the preferred technique for showing activity sequencing.
True
To define activities, the project team should start with reviewing the schedule management plan, scope baseline, enterprise environmental factors, and organizational processes.
True
In project schedule management, what is the next step after defining project activities?
determining their dependencies
In project schedule management, the ultimate goal of which process is to provide a basis for monitoring project progress for the time dimension of the project?
developing a schedule
In project schedule management, which is an output of controlling the schedule?
project management plan update
In project schedule management, which process primarily involve identifying and documenting the relationships between project activities?
sequencing activities
During which relationship is the "from" activity unable start until the "to" activity is started?
start -to-start
Which statement best describes the difference between an activity list and an activity attribute?
An activity attribute is a tabulation of activities to be included on a project schedule whereas an activity list is not.
Which is a similarity between scope control and schedule control?
Both are portions of the integrated change control process under project integration management.
In an AOA network diagram, what occurs when two or more activities follow a single node?
Bursts
Which technique is used for making cost and schedule trade-offs to obtain the greatest amount of schedule compression for the least incremental cost?
Crashing
Which technique involves network diagramming and is used primarily to predict total project duration?
Critical path analysis
What term is used for the amount of time an activity can be delayed without delaying the early start date of any immediately following activities?
Free slack
Which provide a standard format for displaying project schedule information by listing project activities and their corresponding start and finish dates in a calendar format?
Gnatt charts
Which is a similarity between the crashing and fast tracking?
both can shorten the time needed to finish a project
