What does this AoN network look like?

Node points now need to show:

• The tasks
• The earliest start
• The latest start
• The float

They also often show

• The earliest finish
• The latest finish

These are both a function of task duration and start time so are easily calculated.

Again, to find the critical path for the project we do two passes. The earliest start times for each task from its preceding tasks and their durations, the latest start from the descendants and the tasks duration. This gives:

Each task here shows the earliest start time (EST), the duration, the id and task description, the latest start time (LST) and the float. Remember a float of zero defines the critical path.
