Estimates for the Viking project
Traditional ScheduleBig Requirements Up Front
Use WBS to decompose the project into tasksUse Estimating Technique to estimate tasksExpert Judgment (Wideband Delphi)
Re-estimating (when more is known) is often not doneMust estimate each change, or re-estimate project if f enough change occurs

Estimates for the Viking project
•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
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 SD2
• Total the variances• Take the square root of the total
