Which is correct?
The final decision on cloud implementation is up to the CIO and ____.”
As the object of a sentence, the first person singular pronoun is me. The easy way to figure out which to use is to take the other person out of the equation. (You would never say “The decision is up to I,” would you?)
As the subject of the sentence, the first person singular pronoun is I. For example: “The CIO and I will make the final decision.” (You would never say “Me will make the final decision,” would you?)
And never, never use myself in either situation. See more about why not here.
