Part One: Start with the WBS you created for your Unit 2 Assignment (home-improvement, gardening, website creation, corporate office move, family vacation, wedding, or professor approved project) and build a duration estimate using Excel. Use the Generic Excel Workbook as your guide for an example. Go to Course Resources to view the Generic Excel Workbook and the ISA WBS and Network Diagrams for guidance. Remember to cross-check yourself against the grading rubric to ensure you address each and every grading criterion. Remember to use a time duration estimate technique to achieve your durations. You should complete a duration estimate for each activity and summarize the duration at the work package level and also provide a final duration estimate (summary of work packages) for the project. Durations should be shown on the WBS using a start and end date/time. Your time duration estimates are needed for Part Two to create the network diagram. Part Two: Using what you have developed for your Unit 3, Part 1 Assignment duration estimate (which is based on the WBS you created for your Unit 2 Assignment), complete the Assignment for Part 2 by developing a network diagram based on the primary tasks and a Gantt (Bar) chart for a schedule, using either MS Excel, MS Word, or MS Project. Use the ISA WBS in Course Resources as your guide. Remember to cross-check yourself against the grading rubric to ensure you address each and every grading criterion. If you build your time duration estimates in MS Project, the Gantt chart and network diagrams are built automatically. Be careful to check your dependencies (links) between your activities in MS Project, otherwise you may have a Gantt chart and network diagram that does not correctly reflect your project.
