- Network diagram and activity
duration estimates are completed
- Schedule model
Anmerkungen:
- Approved
Realistic
Formal
- Critical path method
Anmerkungen:
- Critical path have zero float
- Involves determine the longest path (critical path),
the earlier and latest an activity can start (and be
completed)
- Critical path: helps to prove how long the project will
take, where to focus your efforts, provides a vehicle
to compress the scehdule, shows which activities
have float
- Near Critical Path
- It's the closest in length to the
critical path, this could be critical
during the project
- Float (slack)
- Total float or slack: is the amount of time an
activity can be delayed without delaying the
project
- Free float or slack: is the amount of time an
activity can be delayed without delaying the
early start date of its sucessor
- Project float: is the amount of time a
Project can be delayed without delaying the
externally imposed Project completion date
- Start Float = Late Start -Early Start
Finish Float= Late Finish
-Early Finish
- You have to completed the forward pass and then
the backward pass
- Schedule compression
- Technique used in project
management to create output faster
without changing the actual scope of
a project. Sometimes, there is a
tangible benefit to significantly
shortening the project timeline
- Fast tracking
- This technique involves taking crtical path
activities that were originally planned in a series
and doing them instead in parallel for some or all of
their duration. Often results in rework , usually
increases risk, and requieres more attention to
comunication.
- Crashing
- This technique adding or adjusting resources in order to compress the
Schedule while maintaining the original Project scope . REsults in
increased costs and may increase risk. Its trades time for money..
- Modeling
- Montecarlo Analysis
- This technique uses computer to simulate the outcome of a
Project based on the three points estimates (optimistic,
pessimistic and most likely. This technique is more accurate tha
other methods because it simulates the actual details of the
Project and calculates probability.
- Can help deal with path convergence , thus adding risk to the Project.
- Resource optimization
- Resource leveling
- Lengthens the Schedule and increases cost in order to deal with a limited amount of
resources, resources availability and resources constraints. Allows level peaks and valleys of
the Schedule.
- Resource Smooting
- Resources are leveled only within the limits of the float of their actvities , so the
completation of activities are not delayed.
