I have some difficulty in understanding the following sentences. Could the teacher help me ? Thank you very mcuh.

1、As a project manager, you will often have projects presented to you that are barely past the big-picture stage
What does "barely past the big-picture stage"mean here?
2、The diffefence between objectives and goals. ...are both examples of objectives. If we clean these statements up a tad and add some measures and dates, we’ll have goals.
What does "clean these statements up a tad and add some measures and dates" mean?
3、 One person may have the authority or influence to twist the arm of another
What is the meaning of " to twist the arm of another" here ?
4、 "Two people act like oil and water when put into the same room together"
What is the meaning of "act like oil and water " in this sentence?

'big picture' = outline
'a tad' = a bit
twist the arm = apply pressure
oil and water don't mix

It is still in thje planningh stage. Not many details have been worked out.

2、The diffefence between objectives and goals. ...are both examples of objectives. If we clean these statements up a tad and add some measures and dates, we’ll have goals.

There is no meaningful difference between objectives and goals.
