TOPIC: Oliver lehman Question

Post-mortem analysis after scheduled finish date of a project shows a CPI of 0.8 and an SPI of 1.25. What is a plausible explanation for that?92
o The project was terminated early. At that time, it was over budget and ahead of schedule.
o The project has produced additional deliverables which were originally not required.
o The project has evidently been finished under budget and behind of schedule.
o The project has evidently been finished over budget and ahead of schedule.

Can someone explain, why the correct answer is A and not D? I am not able to understand how do we determine that the project was terminated early.

Sushil.

Sushil,

I went ahead and wrote to Oliver Lehmann himself and asked for his explanation. Here is what he wrote back:

Once the scheduled finish day has passed, a successfully finished project has an SPI of 1.

It was scheduled to be finished by 100% and has achieved 100% completion. 100% divided by 100% is 1.00.

If a finished project has an SPI >1.00, it has either been finished ahead of schedule and the scheduled finish date lies still in the future, or it must have been cancelled.
