Essential of Software Engineering 4th Edition. Chapter 13 Exercises 13.5

We saw in the EV example shown in Table 13.4 that there is more actual effort spent than what the BCWP indicates on 4/5/2012 because that calculation only includes the completed tasks. Suppose we invent another term called all actual efforts spent (AAES) to include all the efforts spent as of the status date and then use it to compute a new formula: EV9 = AAES / BAC. a. Discuss your opinion of utilizing EV9 instead of EV. b. Because AAES is just a redefined and expanded BCWP, do you believe the SV and CV figures will be more representative of the true project status if we use AAES in computing SV and CV? Why?
