Question 1:
- The critical path follows task A, task D, task G, task J and takes 13 days.
[pic 1]
Task | LS-ES = Total Slack | Min ES’s f successors-EF = Free Slack |
A | 0-0=0 | Min{4;4}-4=0 |
B | 2-0=2 | Min{3;3}-3=0 |
C | 10-4=6 | 5-5=0 |
D | 4-4=0 | 9-9=0 |
E | 5-3=2 | 9-7=2 |
F | 6-3=3 | 4-4=0 |
G | 9-9=0 | 12-12=0 |
H | 7-4=3 | 12-9=3 |
I | 11-5=6 | 13-7=6 |
J | 12-12=0 | 13-13=0 |
- In this case, the estimated finishing time is 12.5 instead of 13 days and the critical path does change, becoming task B, task E, task G and task J.
Question 2:
TBC: 480
Cumulative PV :
PV1 : 130
PV2 : 230
PV3 : 320
Cumulative EV:
EV1 : 30% x 70 + 40% x 190 = 21 + 76 = 97
EV2 : 100% x 70 + 10% x 90 + 100% x 190 = 70 + 9 + 190 = 269
EV3 : 100% x 70 + 10% x 90 + 100% x 190 + 40% x 65 = 295
Cumulative AC :
AC1 : 70
AC2 : 205
AC3 : 255
SPI1: EV1/AC1 = 97/70 = 1.386
SPI2: EV2/AC2 = 269/205 = 1.312
SPI3: EV3/AC3 = 295/255 = 1.157
CPI1: EV1/PV1 = 97/130 = 0.746
CPI2 :EV2/PV2 = 269/230 = 1.169
CPI3 : EV3/PV3 = 295/320 = 0.922
To conclude, we are under budget and behind schedule on weeks 1 and 3.
Question 3:
Before Leveling: Expected finish date is Wednesday 3rd of May 2017.

After leveling: The expected finish date does not change. The date does not change because the leveling affects how Worker1 works on the different tasks. It makes the use of Worker1 more efficient.

The expected finish date is now Friday 14th April 2017. This is because there are more workers available, so tasks can be completed faster.
