In this exercise, you apply the formulas of earned value (EV) analysis to the John’s Move project. Complete the exercise by following these instructions:
Navigate to the location where the student supplement files are stored and open Ch09EV.xls in a spreadsheet program such as MS Excel. Save the file on your computer as Ch09EVStudentName.xls. Four tasks span four weeks. The budgeted cost of work scheduled (BCWS) is shown at the beginning of each bar, as shown in Figure 9.11 "EV Analysis for John’s Move".
Click cell C25 to select it. In the Number group, click the Increase Decimal button two times, if necessary, to display two decimal places. See Figure 9.12 "BAC Calculation".
Move the mouse pointer to the Enter button on the Formula bar. See Figure 9.13 "PV Calculation for Week 1". Entering formulas by using this button keeps the selection on the current cell.
In the spreadsheet, click cell E16. Type =D5+D8 and then, on the Formula bar, click the Enter button. The EV is the sum of the budgeted work that has been performed up to that point in the project. See Figure 9.14 "EV Calculation for Week 1".
Click cell E19. Type =E16−E15 and then, on the Formula bar, click the Enter button. The schedule variance (SV) for week 1 is EV minus the PV. See Figure 9.15 "AC, CV, and SV Calculations for Week 1".
Refer to the definitions of CPI and SPI. Enter formulas in cells E20 and E21 to calculate the CPI and SPI. Recall that formulas begin with an equal sign and use cell names instead of the numbers in those cells. Use the Decrease Decimal or Increase Decimal buttons as needed to display two decimal places. See Figure 9.16 "CPI and SPI Calculations for Week 1".
Refer to the definitions of estimate to complete (ETC) for typical and atypical variances in AC. Enter formulas in cells E22 and E23 to calculate the ETC for typical and atypical CV. Recall that the BAC value is in cell C25. Compare your results to Figure 9.17 "ETC at the End of Week 1 for Typical and Atypical AC".
Refer to the definitions for CV, SV, CPI, SPI, and ETC and write formulas in cells H18 through H23 to calculate those values at the end of week 2. See Figure 9.18 "Calculations for Week 2".
In the spreadsheet, apply what you have learned to perform similar calculations for weeks 3 and 4. See Figure 9.19 "Calculations for Weeks 3 and 4".
Click cell E5. Type 30 and then, on the Formula bar, click the Enter button. Notice that all the calculations that depend on the AC in this cell are recalculated. See Figure 9.20 "Values That Depend on the AC in Cell E5 Change".
Prepare the worksheet for printing:
In the Page Setup dialog box, on the Page tab, click the Landscape button and the Fit To button. See Figure 9.21 "Printout Oriented Horizontally and Forced to Fit on One Page".
In the Page Setup dialog box, on the Header/Footer tab, click the In the Header dialog box, click the Left section, and then type your name. Click the Center section and then type John’s Move. Click the Right section box and type For InstructorName, substituting your instructor’s name. See Figure 9.22 "Your Name and Your Instructor’s Name in the Header".
Review your work in Ch09EVStudentName.xls and use the following rubric to determine its adequacy:
Element | Best | Adequate | Poor |
---|---|---|---|
File name | Ch09EVStudentName.xls | Ch09EVStudentName.xlsx | Did not include student name |
Create a spreadsheet to perform an EV analysis | Formulas that produce the values shown in Figure 9.16 "CPI and SPI Calculations for Week 1" and Figure 9.17 "ETC at the End of Week 1 for Typical and Atypical AC", depending on the value in cell E5; names in header for printout | Same as Best | Could do formulas for weeks 1 and 2 but could not apply knowledge to weeks 3 and 4; errors in formulas; missing header |
Review your work in Ch09EVStudentName.doc and use the following rubric to determine its adequacy:
Element | Best | Adequate | Poor |
---|---|---|---|
File name | Ch09EVStudentName.doc | Same name saved as .docx file | Used a different name |
Use dedicated project management software to manage changes to the WBS | Three screen captures that show the development of the spreadsheet | Same as Best | Missing screens |
