Establish clarity among tasks.
Planning Terminology & Definition of Terms
Activity.
Activity is a specific project task that requires resources and time to complete.
Event.
An event is an end state for one or more activities/performance that occurs at a specific point in time.
Path.
A path is a sequence of lines and nodes in a network.
Dummy activity.
Dummy activity is defined as diagrams to represent dependencies not otherwise possible to show.
Zero-time activity.
Zero-time activities are added just to connect dependent tasks.
Free slack.
Free slack is the amount of time in a schedule that can be taken before the next task is delayed.
Total slack.
Total slack is the amount of time in a schedule that a task can be delayed before an entire project's completion date is delayed.
Network.
Network is a combination of interrelated activities and events depicted with arcs and nodes; constructed left to right, event times, and activity precedence.
The early start date.
The early start dates of the project schedule are the earliest that any activity in the schedule can be scheduled to start given the logic and constraints of the schedule.
The early finish.
The early finish of an activity in the schedule is the earliest that the activity can be scheduled to be completed given the logic and constraints of the schedule.
The late start.
The late start of an activity is the latest that a project activity can be scheduled to be started without having to reschedule the calculated early finish of the project.
The late finish.
The late finish of an activity is the latest that a project activity can be finished without having to reschedule the late finish of the project. The late finish of the project is the late finish of the last activity to be completed in the project.
Critical path.
A critical path is the sequence of project network activities which add up to the longest overall duration, regardless if that longest duration has float or not. This determines the shortest time possible to complete the project. There can be 'total float' (unused time) within the critical path.
Slack.
Slack is important when managing a project because it is very rare that things don't change while working on a project: budgets change, schedules change, available resources change and so do task priorities; without slack time it will be very challenging to be able to manage the project in a flexible way without causing tasks to be stuck or not have time to handle urgent things that were introduced.
