Scheduling Dates for Work Breakdown Structure (WBS) Elements
Objective
After completing this lesson, you will be able to schedule basic dates in WBS elements
Time Scheduling with WBS Elements
Basic Date Planning with WBS Elements

The preceding figure illustrates both manual planned dates and dates calculated by the system.
Basic Date Planning with WBS Elements
Basic dates can be extrapolated from lower to higher-level WBS elements or, conversely, inherited from higher to lower-level WBS elements. You can check the consistency of your scheduling data within the WBS structure.
In the execution phase, you can enter actual dates by dragging your mouse. In the project planning board or the information system, you can compare the actual dates with the planned basic dates.
Planning Methods
Top Down (checks consistency)
Bottom Up (extrapolates and extends)
Free Planning (neither checks nor calculates)
Strict Bottom Up (extrapolates, extends, and shortens)
