Definition
| Any schematic display of the logical relationships of project activities. |
|
|
Term
|
Definition
| sequence of activities defined by the project network logic. |
|
|
Term
|
Definition
| A point when an activity is either started or completed. Often used in conjunction with AOA networks, they consume no resources & have no time to completion associated with them. |
|
|
Term
|
Definition
| One of the defining points of a network; a junction point joined to some or all of the others by dependency lines (paths). |
|
|
Term
|
Definition
| Those activities that must be completed prior to initiation of a later activity in the network. |
|
|
Term
|
Definition
| Activities that cannot be started until previous activities have been completed. These activities follow predecessor |
|
|
Term
|
Definition
| The earliest possible date on which the uncompleted portions of an activity can start, based on the network logic & any schedule constraints. |
|
|
Term
|
Definition
| The latest possible date that an activity may begin without delaying a specified milestone (usually the project finish date). |
|
|
Term
|
Definition
| Network calculations that determine the earliest start/earliest finish time (date) for each activity. |
|
|
Term
|
Definition
| Calculation of late finish times (dates) for all uncompleted network activities. The latest finish dates are determined by working backward through each activity. |
|
|
Term
|
Definition
| An activity with two or more immediate predecessors (tasks flowing into it). They can be located by doing a forward pass through the network. |
|
|
Term
|
Definition
| An activity with two or more immediate successor activities (tasks flowing out from it). these activities can be located by doing a backward pass through the |
|
|
Term
|
Definition
| The amount of time an activity may be delayed from its early start without delaying the finish of the project. |
|
|
Term
|
Definition
| The path through the project network with the longest duration. These path may change from time to time as activities are completed ahead of or behind schedule. Critical path activities are identified as having zero float in the project. |
|
|
Term
| Critical Path Method (CPM) |
|
Definition
| A network analysis technique used to determine the amount of scheduling flexibility (the amount of float) on various logical network paths in the project schedule network, & to determine the minimum total project duration. It involves the calculation of early (forward scheduling) & late (backward scheduling) start & finish dates for each activity. Implicit in this technique is the assumption that whatever resources are required in any given time period will be available. |
|
|
Term
| Resource-limited schedule |
|
Definition
| A project schedule whose start & finish dates reflect expected resource availability. The final project schedule should always be resource-limited. |
|
|
Term
| Program Evaluation & Review Technique (PERT) |
|
Definition
| An event- & probability-based network analysis system generally used in projects where activities & their durations are difficult to define. |
