From Q1:
Suppose there are 8 activities in your project with the following information.
Activity |
Immediate Predecessor |
Processing Time (days) |
Processing Cost ($ per day) |
---|---|---|---|
A | B | 5 | 20 |
B | - | 4 | 40 |
C | A,B | 6 | 30 |
D | A | 7 | 10 |
E | C,D | 6 | 25 |
F | C | 5 | 40 |
G | E,F | 4 | 25 |
H | F | 3 | 50 |
Base on the information of the project in question 1, you monitor the status of the project at the end of day 18 and found out the following information.
Activity | % Work Completion | Incurred Cost |
---|---|---|
A | 100% | $100 |
B | 100% | $160 |
C | 100% | $180 |
D | 100% | $80 |
E | 17% (equivalent to 1 day of work) | $40 |
F | 20% | $50 |
G | - | - |
H | - | - |
Problem1: What is the closest number to the planned value of this project?
A.)$575 B.)$610 C.)$620
Problem2: From the information above, what is the closest number to the earned value of this project?
A.)$610 B.)$620 C.)$575
Problem3 :From the above information, what is the performance of this project?
A.)Right on the budget B.)Over budget by 5.7% C.)Over budget by 7.2%
Problem4: From the above information, what is the performance of this project in term of schedule?
A.)Behind schedule by 7.2% B.)Behind schedule by 5.7% C.)Right on schedule
Problem5 :Suppose the behavior of the cost is likely to continue this trend, what is the new estimation of cost at the end of the project?
A.)$1,177 B.)$1,145 C.)$1,197
Problem6 :Suppose the behavior of the cost up to the monitoring date is unusual, and the management can fix it and all the cost will likely to be as plan, what is the new estimation of cost at the end of the project?
A.)$1,145 B.)$1,177 C.)$1,197
Budget is the row-wise sum up to Day-26
PV is the row-wise sum up to Day-18
EV = Budget * % complete
-------------------
A) PV = $620
Actually PV is coming at $680. But no such option is given, so we select $620 which is the closest (there must be some flaw in the question set - check that).
B) EV = $575
C) Over-budget by 5.7%
% overbudget = (AC - EV) / AC = (610 - 575) / 610 = 5.7%
D) Behind schedule by 7.2%
% behind schedule = (PV - EV) / PV = (620 - 575) / 620 = 7.2%
E) $1177
CPI = EV / AC = 575 / 610 = 0.9426
EAC = AC + (BAC - EV) / CPI = 610 + (1110 - 575) / 0.9426 = 1177
F) $1145
EAC = AC + (BAC - EV) = 610 + (1110 - 575) = 1145
