STEP |
ACTION |
|
1 |
Use the WBS and activity sequencing to complete the network |
|
2 |
Decide which activities will be the start and finish activities |
|
3 |
Link the activities to their predecessors as identified in the activity sequencing |
|
4 |
All nodes must be entering or exit lines except for the start and finish nodes |
|
5 |
Ensure that there are no loops |
|
6 |
Eliminate superfluous lines |
