2. steps to effective time management
• Examine the Contract
• List Major Contractual Obligations
• Divide Project into Major Work Areas
• Building Technology Implies Sequence
• Find Productivity, Duration, Cost
• Calculate Initial Schedule
• Schedule Adjustments
• Resource Evaluation
• Time / Cost Trade-off
• Total Project Cash Flow
• Include All Important Procurement
3. Project Network Diagrams
• Network diagrams show the precedence
relationships among activities
• It’s easier to understand these relationships
graphically
• Network diagrams help to understand the flow of
work in a project
• Network diagrams are a useful tool for project
planning and control, as well as for scheduling
• One (perhaps exaggerated) claim is that the
network represents ¾ of the planning process
4. Two Versions of Network Diagrams
Activity-on-Arrow (AOA) networks
– also called Arrow Diagramming Method
(ADM)
– simpler for projects with many dependencies
– emphasizes events; milestones can be easily
flagged
– sometimes requires dummy activities
5. Two Versions of Network Diagrams
• Activity-on-Node (AON) networks
– also called Precedence Diagramming Method
(PDM)
– easier to draw for simple projects
– emphasizes activities
– no dummy activities
6. Activities vs. Events
• Activity – a chunk of work that is part of the
project; an activity may be broken down into
multiple subactivities
• Event – a significant point in time during the
project, such as a milestone event; an event
could be the time at which an activity is
completed or the time at which related
concurrent activities have all completed
• Dummy Activity – an artificial activity with zero
time duration that only shows a precedence
relationship among activities
