4. Project Schedule Management
Project schedule management is the processes
required to manage the timely completion of the
project.

5. Key Terms
• Schedule baseline: the version of the schedule model
used to manage the project; it is what the project team’s
performance is measured against.
• Schedule compression: a technique to shorten an already
developed schedule.
• Crashing: schedule compression technique by adding resources.
• Fast tracking: schedule compression technique in which activities
normally done in sequence are performed in parallel for at least a
portion of their duration.
• Activity list: list of activities to be managed in the project
schedule.
• Network diagram: a diagram of project activities that
shows the sequential relationships of activities using
arrows and nodes.

6. Key Terms (continued)
• Contingency (schedule) reserve: the estimated duration
within the schedule baseline, which is allocated for
identified risks that are accepted.
• Management reserve: specified amount of the project
duration (not included in baseline) withheld for
management control purposes and are reserved for
unforeseen work that is within the scope of the project.
• Critical path: the longest duration path through a network
diagram, and it determines the shortest time it could take
to complete the project.
• Milestone: significant events within the project schedule;
not work activities and have no duration.

7. Key Terms (continued)
• Near critical path: closest in duration to the critical path.
• Total float: the amount of time an activity can be delayed
without delaying the project end date or an intermediary
milestone.
• Free float: the amount of time an activity can be delayed
without delaying the early start date of its successor(s).
• Project float: the amount of time a project can be delayed
without delaying the externally imposed project
completion date required by the customer.

8. Key Terms (continued)
• Lead: the amount of time a successor activity can be
advanced with respect to a predecessor activity.
• Lag: the amount of time a successor activity will be
delayed with respect to a predecessor activity.
• Student syndrome (procrastination): people start to apply
themselves only at the last possible moment before
deadline.
• Parkinson’s Law: work expands to fill the time available
for its completion.

9. Trends & Emerging Practices
• Iterative scheduling with backlog
• On-demand scheduling

10. Tailoring Considerations
• Life cycle approach
• Resource availability
• Project dimensions

11. Considerations for Adaptive Environments
• Adaptive approaches use short cycles to
undertake work, review the results, and adapt as
necessary.
• To address the full delivery life cycle for larger,
enterprise-wide systems, a range of techniques
utilizing the predictive, adaptive, or hybrid
approach may need to be adopted.
• The role of project manager does not change.
