3 Learning Outcomes: Plan (verb) reate a plan for an intermediate size software project and manage to the plan. Maintain a software project schedule. n n n Do some Earned Value Analysis Examine Estimated to omplete Values Determine good and bad Trends in the progress

4 You have the WB and have identified the activities. Where do you start with Earned Value Analysis? n Think for seconds n Turn to a neighbor and discuss it for a minute n Then can we tawlk?

5 Earned Value Exercise (PV, A, EV) Task Develop and install ten printer drivers. Budget - $100,000 ($10K per printer driver) Time 10 weeks (1 printer driver per week) At week 5: 4 printer drivers developed and installed $47,500 spent to date PV = $??? A = $??? EV = $??? Q1, 2, 3

6 Derived EVA Metrics: V and V V = EV A V = EV PV ost Variance n n omparison of the budgeted cost of work performed with actual cost Negative V means the project is over budget chedule Variance n n omparison of work performed during a period of time to what was scheduled to be performed Negative V means the project is behind schedule Q4

over budget chedule Variance n n omparison of work performed during a period of

7 Earned Value Exercise (V) ost Variance (V) V = EV - A = $??? Good News: If V value is positive, the project is currently under budget (spending less than planned for the work) Bad News: If V value is negative, the project is currently over budget (spending more than planned for the work)

budget (spending less than planned for the work) Bad News: If V value

8 Earned Value Exercise (PI) ost Performance Index (PI) PI = EV / A =??? Good News: If PI value is >1 or =1, the project cost trend is currently under or at planned budget Bad News: If PI value <1, the project cost trend is currently over budget Q5

9 Earned Value Exercise (V%) ost Variance % (V%) V% = V / EV =???% Good News: If V% value is positive, the project is currently under budget by the V% Bad News: If V% value is negative, the project is currently over budget by the V%

10 Awkward!!!

11 Earned Value Exercise (V) chedule Variance (V) V = EV - PV =??? Good News: If V value is positive, the project is currently ahead of schedule Bad News: If V value is negative, the project is currently behind schedule

12 Earned Value Exercise (PI) chedule Performance Index (PI) PI = EV / PV =??? Good News: If PI value is >1 or =1, the project schedule trend is currently ahead or on planned schedule Bad News: If PI value <1, the project schedule trend is currently behind schedule Q6

13 Earned Value Exercise (V%) chedule Variance % (V%) V% = V / PV =???% Good News: If V value is positive, the project is currently ahead of schedule Bad News: If V value is negative, the project is currently behind schedule Q7

14 Earned Value Exercise Task Develop and install ten printer drivers. Budget - $100,000 ($10K per printer driver) Time 10 weeks (1 printer driver per week) At week 5: 4 printer drivers developed and installed $47,500 spent to date PV = $50,000 A = $47,500 EV = $40,000 V = -$7,500 PI = 0.84 V% = -19% V = -$10,000 PI = 0.80 V% = -20%

week) At week 5: 4 printer drivers developed and installed $47,500 spent to date

15 But, when will we complete? Estimate at ompletion (EA) Actual costs to date plus a new estimate for all remaining work (original plan no longer valid) EA = A + ET (ET Estimate to omplete) Q8

16 Well, it s a little involved Estimate at ompletion (EA) Actual costs to date plus remaining budget (current variances viewed as atypical of future variances) Actual costs to date plus remaining budget modified by a performance factor (PI) (current variances are viewed as typical of future variances) EA = A + [(BA - EV) / PI] ~EA = BA / PI Q8

costs to date plus remaining budget modified by a performance factor (PI) (current

17 Earned Value Performance Indices Project: Alpha Good Progress Under budget Ahead of schedule Over budget Behind schedule Project Week

6 Under budget Ahead of schedule Over budget

18 Earned Value Performance Indices Project: Beta Divergent Progress Under budget Ahead of schedule Over budget Behind schedule Project Week

19 Earned Value Performance Indices Project: harlie Losing Ground Under budget Ahead of schedule Over budget Behind schedule Project Week Q9
