4. Agenda Member Introduce Combination of Wideband Delphi to generates schedule, budget and resource 1 2 3 4 Estimates for the Viking project

5. Traditional Schedule  Big Requirements Up Front Use WBS to decompose the project into tasks Use Estimating Technique to estimate tasks Expert Judgment (Wideband Delphi)  Re-estimating (when more is known) is often not done  Must estimate each change, or re-estimate project if f enough change occurs Introduce

7. WBS for Viking project

8. Wideband Delphi  Assumptions established by team  Team discusses assumptions where estimates vary  Goal: Team working with same & correct assumptions Estimates for the Viking project

9. Agenda Member Introduce Combination of Wideband Delphi to generates schedule, budget and resource 1 2 3 4 Estimates for the Viking project

10. List all task of Viking project ( base on WBS ) Members estimate time (hour) to complete the task. Members check each other estimate, and adjust to be more suitable and explain in Assumption. After that, teams discuss each task to find the best estimated time for the task. Combination of Wideband Delphi

11. When we have estimated numbers, we will calculate as below: Because > 10 tasks, so team using a complex standard deviation calculation: Compute the SD of each task (or feature): Individual SD = (IndividualWorstCaseEst- IndividualBestCaseEst)/6 Compute each task’s variance: Task variance = Task’s SD 2 Total the variances Take the square root of the total Combination of Wideband Delphi
