Dear fellow Prepcast students,
Here is one question that apparently is easy -
When the project manager completes the detailed project schedule, who should approve it? Choose the best answer -
A> The Project Sponsor
B> The Project Team
C> Functional managers
D> Customer
Based on my understanding, the answer I chose was A. But it came out to be wrong! The answer given was C.

Unable to digest it, I thought let me seek opinion of Prepcast Gurus & community.
Any plausible explanation for the answer C? (The text of the question was exactly as mentioned here.)
I feel it's the Project Sponsor who should approve the project schedule.
Thanks for your time and help.
Best regards,
Surendra
