Project Time Management 6 Where Do Schedules Come From? Defining Activities ◼ Project schedules grow out of the basic document that initiate a project ◼ Project charter includes start and end dates and budget information ◼ Scope statement and WBS help define what will be done ◼ Activity definition involves developing a more detailed WBS and supporting explanations to understand all the work to be done
