Creating a Schedule Using Creating a Schedule Using Divide and ConquerDivide and Conquer

Outline the work that needs to be Outline the work that needs to be done using a done using a Work Breakdown Work Breakdown Structure Structure ((WBSWBS))

Turning a WBS into a schedule byTurning a WBS into a schedule by– Defining task dependenciesDefining task dependencies– Estimating the duration of each taskEstimating the duration of each task– Assigning peopleAssigning people– Adding milestonesAdding milestones
