Activity Attributes
Inherent characteristics that describe a scheduled activity and its place in a schedule network. Given suitable software, these attributes may be used for sorting purposes. [D05603]

 RMW
Activity Based Costing ("ABC")
Bottom up estimating and summation based on material and labor required for tasks. [D05242]

N

 SU
A methodology that measures the cost and performance of activities, resources, and cost objects. Resources are assigned to activities, then activities are assigned to cost objects based on their use. Activity based costing recognizes the causal relationships of cost drivers to activities. [D04680]

N

N

 PMK87
The length of time (hours, days, weeks, months) that it takes to complete an activity. This information is optional in the data entry of an activity. Work flow (predecessor relationships) can be defined before durations are assigned. Activities with zero durations are considered milestones or hammocks. [D00036]

N

 WST
PMST

The estimation of the number of work periods that will be needed to complete the activity. [D00037]

 WST
Activity Elaboration
A more detailed explanation of the work involved in the Activity, possibly by describing a series of tasks. [D02354]

N

 RMW
Activity File
A file containing all data related to the definition of activities on a particular project. [D00038]

N

 WST
Activity ID
A unique code identifying each activity in a project. [D00039]

N

 WST
Activity Identifier
See Activity ID or Activity Code. [D05605]

JN

  
Activity Listing
A summary of schedule activities, usually complete with their respective Activity Attributes. [D05606]

JN

 RMW
Activity Network
A flow diagram showing the activities of a plan and their interdependencies. The network shows each activity's duration, earliest start and finish times, latest start and finish times and float. Also known as "planning network". See also Critical path [D05243]

N

 PRNC2 2002
Activity Node Net
Project plan in the form of a structural network where the activities are denoted graphically by arrows. [D00041]

N

 NPMT
Activity on Arc ("AOA")
In documenting and drawing a network one may place the activities on the arcs or on the nodes (Activity on Node) [D00042]

N

 OTOB p271-4
Activity on Arrow
A network diagram showing sequence of activities, in which each activity is represented by an arrow, with a circle representing a node or event at each end. [D03709]

N

 PPS&C p338
See Arrow Diagramming Method. [D00048]

N

  
Activity on Node
A network where activities are represented by a box or a node linked by dependencies. [D00049]

N

 WST
See also Activity on Arc and Precedence Diagram Method. [D00043]

N

  
A network diagram showing sequence of activities, in which each activity is represented by a box or circle (that is a node) and these are interconnected with arrows to show precedence of work. [D03710]

N

 PPS&C p338
Activity Oriented
A planning approach focused primarily on activities rather than events. [D00044]

N

 NPMT
Activity Oriented Schedule
Schedule which presents information in terms of activities (i.e. periods of time, as opposed to points in time, e.g. milestone dates). See also Precedence Diagramming. [D00045]
