Introduction to Project Time Management


Includes the processes required to ensure timely completion of the project.
The major processes in developing the project time schedule are:
– Activity Definition
– Activity Sequencing
– Activity Duraton Estimating
– Schedule Development
– Schedule Control




Activity Definition
– Identifying and documenting the specific activities that must be performed to produce the various project derivables and subderivables identified in the WBS
