, the president said that Mr Trump should always "respect" US institutions.
He added he had tried to impress upon his successor that running the White House is an entirely different role to any other job.
He said: "You can't manage it the way you would manage a family business.
"You have to have a strong team around you. You have to have respect for institutions and the process to make good decisions because you are inherently reliant on other folks."
He told the chief anchor George Stephanopoulos he had chatted with Mr Trump about having confidence in US intelligence agencies.
He said: "When I talked to him about our intelligence agencies, what I said to him is that there are going to be times where you've got raw intelligence that comes in and in my experience, over eight years, the intelligence community is pretty good about saying 'look we can't say for certain what this means'."
The out-going president also commented on the fact he does not think Mr Trump has spent much time "sweating the details" of being president.
He said this could be a strength or a weakness as it could give him a fresh approach but also means he could be lacking in vital information.
