You should be able to come up with 30â€“100 activities easily for your schedule baseline. Once those activities have been identified, finish your schedule by plugging in start and finish dates, durations, predecessor relationships, and adding cost and resource names. Resource names and cost can be added in the main summary page or directly in the resource sheet. Your project name must go in the first row, and all other activates should be indented under it. You should link all activities to summary tasks and subactivities to the main activity. You may make assumptions for any of this work, and estimates do not need to be real.
