Determination of appropriate depth requires practice. •A WBS is not intended to be an exhaustive list of all the tasks within a project. •Development of a WBS is necessary prior to scheduling. The WBS lays the foundation upon which scheduling and resource allocation can be accomplished. •A WBS should not built around organizational constructs. Work/tasks should be unconstrained by organization, but tasks will be assigned to organizational elements. •Once finalized, resourced and scheduled against, the WBS should be subjected to configuration control. Some lecture content courtesy of Prentice Hall, Rights Reserved Individual Practice Exercise Practice Exercise (15 minutes) – - Sit with your project team - Open up MS Excel or MS Word on your desktops - Create a three level WBS with task dependencies & save - Here are some project options: Buying a House • Agents • House location/budget • Loans • House selection • Negotiation • Inspection • Closing Building a Boat Dock • Design concept • Budget • Contractors • Detailed design • Permits •Build • Inspection Some lecture content courtesy of Prentice Hall, Rights Reserved Project Scheduling • Key Steps • • • • • Identifying precedence relationships Sequencing activities Determining activity times & costs Estimating material & worker requirements Determining critical activities • Purpose of Scheduling Steps • • • • Shows the relationships between activities and whole project. Identifies the precedence relationships among activities. Encourages setting realistic time and cost estimates. Helps make better use of people, money, and material resources by identifying critical bottlenecks in the project.

(Decide which activities must precede and which must follow others.) Draw the network connecting all of the activities Assign time and/or cost estimates to each activity Compute the longest time path through the network. This is called the critical path Use the network to help plan, schedule, monitor, and control the project Some lecture content courtesy of Prentice Hall, Rights Reserved Determining the Project Schedule Perform a Critical Path Analysis The critical path is the longest path through the network The critical path is the shortest time in which the project can be completed Any delay in critical path activities delays the project Critical path activities have no slack time Some lecture content courtesy of Prentice Hall, Rights Reserved Task Duration Predecessor A B 2 3 A C D 2 4 A B Question - What is the duration of this project and what is the critical path?
