Project Management – Components of an Activity Network

network diagram
a graphic representation for how the project will proceed, often using nodes
node label
the unique identifier used to make certain every task and activity is understood
immediate predecessor
a task or activity that must be completed immediately before a certain task can be performed
sequence
What process do label nodes identify?
tasks
As they become better understood, activities are broken down into ________.
concurrent tasks
tasks that can be done at the same time
successor tasks
tasks that can only be done after certain work is completed
predecessor tasks
tasks that need to be completed before certain work is started
serial tasks
tasks that can be done in a single stream of tasks

What is a graphic representation for how a project will proceed?
document
Is WBS a document or graphic representation for how a project will proceed?
discretionary dependency
when the PM can choose based on resource availability, including people, money/budget, and other materials
mandatory (or logical) dependencies
when the sequence of tasks are affected by legal requirements or on other activities
internal dependencies
when the sequence of tasks are affected by their impact on milestones as defined by the project requirements or by management control
external dependencies
when the sequence of tasks rely on external resources or forces
physical

in a single stream of tasks
How are serial activities performed?
different
Do tasks that can be performed concurrently involved the same or different resources?
external dependency
Activities are rushed to match a competitor’s release date. What type of dependency is this an example of?
physical dependency
Tasks are scheduled for different days due to limited space for crews. What type of dependency is this an example of?
logical dependency
Two task activities depend on each other due to legal requirements. What type of dependency is this an example of?
internal dependency
Tasks are linked to regular milestones required by management. What type of dependency is this an example of?
