From Steve Jobs: The Exclusive Biography  

I think collaboration is really important. Education is an example of an integrated product. It's vital that senior management teams meet frequently, and often, with a clear agenda, to ensure that the team is collaborative.

This approach also applied to key hires. He would have candidates meet the top leaders rather than just the managers of the department where they wanted to work.  

It's important that everyone in the senior management team meets any potential new members of staff. The new employees have to fit in. They have to be right for the team. That means that all leaders need to meet them.
