Common WBS terms

Work Packages

Elements on the lowest level of the WBS

Elements may exist below the work package for

resource and/or detail task planning and tracking

Code of Accounts Charge codes assigned to the various elements in

the WBS

WBS Tips

Name work packages (WBS elements) forhard deliverables

Something you can lay on the table

Limit the duration of work packages to oneor two weeks

Why Do a Schedule, Anyway?


21/28

Why Do a Schedule, Anyway?

Eliminate or reduce uncertainty

Improve efficiency of the operation

Obtain better understanding of the project

objectives Provide a basis for monitoring and controlling

the work


22/28

Steps to Develop a Schedule

1. Develop WBS for project2. Assign durations to activities associated with each

work package in the WBS

Enter durations in the scheduling program, not

start and finish dates Designate selected activities as milestones

3. Develop the logic for the schedule

Define the predecessor and successor activitiesfor each activity on the schedule

4. Assign resources to the activities

5. Select report formats for updating and trackingprogress


23/28

Schedule formats

PERT (Project Evaluation and ReviewTechnique)

Requires three estimates of duration foreach activity in the schedule

Results in a statistical probability of thelikelihood of achieving the schedule asplanned

Calculates a critical path Longest duration path through the schedule

Dictates the earliest completion date


24/28

Schedule formats

CPM (Critical Path Method) Only one duration assigned to each activity

Calculates a critical path
