activity
answer
An element of work normally found on the WBS that has an expected duration, cost, and resource requirements; also called a task
question
activity attributes
answer
information about each activity, such as predecessors, successors, logical relationships, leads and lags, resource requirements, constraints, imposed dates, and assumptions related to the activity
question
activity list
answer
a tabulation of activities to be included on a project schedule
question
activity-on-arrow
answer
a network diagramming technique in which activities are represented by arrows and connected at points called nodes to illustrate the sequence of activities; also called arrow diagramming method
question
arrow diagramming method
answer
a network diagramming technique in which activities are represented by arrows and connected at points called nodes to illustrate the sequence of activities; also called activity-on-arrow
question
backward pass
answer
a project network diagramming technique that determines the late start and late finish dates for each activity in a similar fashion
question
baseline dates
answer
the planned schedule dates for activities in a Tracking Gantt chart
question
buffer
answer
additional time to complete a task
question
burst
answer
a single node followed by two or more activities on a network diagram
question
crashing
answer
a technique for making cost and schedule trade-offs to obtain the greatest amount of scheduling compression for the least incremental cost
question
critical chain scheduling
answer
a method of scheduling that takes limited resources into account when creating a project schedule and includes buffers to protect the project completion date
question
critical path
answer
Generally, but not always, the sequence of schedule activities that determines the duration of project. It is the longest path through the project. (see also CPM)
question
critical path method
answer
a project network diagramming technique used to predict total project duration
question
dependency
answer
the sequencing of project activities or tasks; also called a relationship
question
discretionary dependencies
answer
sequencing of project activities or tasks defined by the project team and used with care since they may limit later scheduling options
question
dummy activities
answer
activities with no duration and no resources used to show a logical relationship between two activities in the arrow diagramming method of project network diagrams
question
duration
answer
the actual amount of time worked on an activity plus elapsed time
question
early finish date
answer
the earliest possible time an activity can finish based on the project network logic
question
early start date
answer
the earliest possible time an activity can start based on the project network logic
question
effort
answer
the number of workdays or work hours required to complete a task
question
external dependencies
answer
sequencing of project activities or tasks that involve relationships between project and non-project activities
question
fast tracking
answer
a schedule compression technique in which you do activities in parallel that you would normally do in sequence
question
feeding buffers
answer
additional time added before tasks on the critical path that are preceded by non-critical-path tasks
question
finish-to-finish dependency
answer
a relationship on a project network diagram where the "from" activity must be finished before the "to" activity can be finished
question
finish-to-start dependency
answer
A relationship on a project network diagram where the "from" activity must be finished before the "to" activity can be started
question
float
answer
the amount of time a project activity may be delayed without delaying a succeeding activity or the project finish date; also called slack
question
forward pass
answer
a network diagramming technique that determines the early start and early finish dates for each activity
question
free slack
answer
The amount of time you can delay the start of a task without delaying the early start of a successor task.
question
gantt chart
answer
a standard format for displaying project schedule information by listing project activities and their corresponding start and finish dates in a calendar format; sometimes referred to as bar charts
question
late finish date
answer
the latest possible time an activity can be completed without delaying the project finish date
question
late start date
answer
the latest possible time an activity may begin without delaying the project finish date
question
mandatory dependencies
answer
sequencing of project activities or tasks that are inherent in the nature of the work being done on the project
question
merge
answer
two or more nodes that precede a single node on a network diagram
question
milestone
answer
a significant event that normally has no duration on a project; serves as a marker to help in identifying necessary activities
question
multitasking
answer
working on more than one task at a time
question
murphy's law
answer
the principle that if something can do wrong, it will
question
network diagram
answer
a schematic display of the logical relationships or sequencing of project activities
question
node
answer
the starting and ending point of an activity on an activity-on-arrow diagram
question
parkinson's law
answer
work expands to fill time available for completion.
question
PERT weighted average
answer
(optimistic time + 4 * most likely time + pessimistic time)/6
question
precedence diagramming method
answer
A network diagramming technique in which boxes represent activities
question
probabilistic time estimates
answer
duration estimates based on using optimistic, most likely, and pessimistic estimates of activity durations instead of using one specific or discrete estimate
question
program evaluation and review technique (PERT)
answer
a project network analysis technique used to estimate project duration when there is a high degree of uncertainty with the individual activity duration estimates
question
project buffer
answer
additional time added before the projects due date
question
project time management
answer
the processes required to ensure timely completion of a project
question
relationship
answer
the sequencing of project activities or tasks; also called a dependency
question
resource breakdown structure
answer
a hierarchical structure that identifies the project's resources by category and type
question
resources
answer
people, equipment, and materials
question
schedule baseline
answer
the approved planned schedule for the project
question
slack
answer
the amount of time a project activity may be delayed without delaying a succeeding activity or the project finish date; also called float
question
slipped milestone
answer
a milestone activity that is completed later than planned
question
SMART criteria
answer
guidelines to help define milestones that are specific, measurable, assignable, realistic, and time-framed
question
start-to-finish dependency
answer
a relationship on a project network diagram where the "from" activity cannot start before the "to" activity is finished
question
start-to-start dependency
answer
A relationship on a project network diagram where the "from" activity cannot start until the "to" activity starts
question
task
answer
an element of work normally found on the WBS that has an expected duration and resource requirements; also called an activity
question
Theory of Constraints
answer
a management philosophy that states that any complex system at any point in time often has only one aspect or constraint that is limiting its ability to achieve more of its goal
question
three-point estimate
answer
an estimate that includes an optimistic, most likely, and pessimistic estimate
question
total slack (total float)
answer
the amount of time an activity may be delayed form its early start without delaying the planned project finish date
question
tracking gantt chart
answer
a Gantt chart that compares planned and actual project schedule information
