~Proceed with project planning.
~Let a box represent each activity with a duration.
~Activity dependency is shown by a line between boxes.
~Each project has single start and Finish activities. These may be of zero duration.
~Each network path is continuous.
~Activities are assigned unique numbers.
~Line length is meaningless and arrow heads are optional.
~Subnetworks can combine to make a master network.
~There are no dummy activities with the precedence diagram.
~Revisions are easily made, node positioning is not critical and activity numbers need not change.
Concrete Utility Pit, Precedence Diagram
This subnetwork precedence diagram results from project planning -- simple footing pierced by electrical service and water pipes.
Proceed with project scheduling.
Estimate activity durations (customary work days):
~ CPM - uses a single time estimate
~ PERT - uses three time estimates (TE): minimum, most likely, maximum.
Perform network calculation for both activity and project start and Finish times (forward and backward pass).
