Types of Diagrams
What is precedence diagramming?
This is the EARLIEST possible time the activity could start based on the project network
What is Early Start?
Shorten the schedule without reducing the project scope to meet schedule constraints
What is schedule compression?
Starts when another task finishes
What is start to finish?
The activity is on the arrow.
Tells you the amount of time that an activity in a project network can be delayed without causing a delay to subsequent activities of project completion.
What is slack or float?
Assigning additional resources to an individual work package to get it done sooner
What is crashing the schedule?
Task finishes before another task starts
What is finish to start?
The activity is on the node.
What is an AON diagram?
This is the LATEST possible time the activity can start without delaying the project finish date based on the project network.
What is Late Start?
Scheduling consecutive tasks to concurrent
What is fast tracking?
Both tasks must start at the same time
Start to start
The activity is in the box.
What is an AIB diagram?
This represents how much an activity can slip without impacting a successor activity. This measure combined with slack determines which activities receive priority over resources.
What is free slack or float?
Method that smooths out peaks and valleys in schedule.
What is resource leveling?
Tasks must finish at the same time
Finish to finish
This is the EARLIEST possible time the activity can finish based on the project network.
What is Early Finish?
Minimizes period-by-period variations by shifting tasks
What is a benefit of Resource Leveling?
This is the LATEST possible time the activity can finish without delaying the project finish date based on the project network.
What is Late Start?
Indicates the task is on the critical path.
What is the task has a float of 0?
