6.5 Develop Schedule:
Questions:
- Can we have more than one critical path?
- Yes, increasing the risk.
- Can we change the critical path?
-
- Can the critical path have negative total float?
- Yes, it indicates the project is behind schedule.
- A sequence of activities with lesser criticality than the main critical path.
Float (or Slack):
- Float (Total Float): The amount of time a schedule activity can be delayed without delaying the project finish date or violating a schedule constraint.
- Free Float: The amount of time an activity can be delayed without delaying the early start of any succeeding activity. Free float occurs when two or more activities share a common successor.
- Project Float: The amount of time a project can be delayed without delaying the externally imposed project completion date or the date previously committed by the project manager.

Schedule Compression:
- Crashing usually results in increased cost.
- The option with maximum compression and minimum cost impact is selected.
-
- Fast tracking may result in rework and increased risk.
- Communication requirements increase during fast tracking.

Output of Process:
- Output of the schedule model, including planned dates, durations, milestones, and resources.
- At the start of execution, the Project Schedule is the same as the Schedule Baseline.
- As work progresses, updates are made to the Project Schedule.
- The latest version of the schedule is called the “Project Schedule.”
- The schedule can be displayed in:
- Milestone Charts (Master Schedule)
- Project Schedule Network Diagram (PDM)
-
- A specific version of the project schedule from the schedule network analysis.
- Accepted and approved by appropriate stakeholders.
- Can only be changed through formal change control procedures.
- A component of the project management plan.
What?
- Process of analyzing activity sequence, duration, resource requirements, and constraints to create a project schedule model.
Why?
- A viable and acceptable schedule model determines the planned start and finish dates for project activities and milestones.
When?
- Iterative process, performed throughout the project.
How?
- Once the project start or finish dates have been set, the project staff assigned to activities review their activities. The schedule is then analyzed to:
- Estimate the minimum project duration (critical path) and determine schedule flexibility.
- Identify conflicts with the resource calendar and determine if resource optimization is required.
- Identify conflicts with milestones and determine if schedule compression is needed.
- Review and revise duration estimates, resource estimates, and schedule reserves for risks.
- Establish an approved project schedule to serve as a baseline for tracking progress.
