What is a Fully Integrated Engineer™?
Most engineers are just that... engineers. They contribute their technical know-how. They answer questions and solve problems. And in a real way it's very much "Here is my answer, now management can do what it will with my answer."

That is how things are generally in a technical organization.

But what would it be like if engineers not only solved problems, but could explain the implications of those technical answers from a broader perspective? What would it be like if they could be fully integrated into no only the technical perspective of the team, but the operational perspective and from the interdepartmental perspective? What if your engineers understand that they had to understand the implications of their decisions on a broader horizon? What if your engineers learned to communicate, and influence, and interact "systemically" not just from their own world view but with a interdepartmental view?

Then you would have a Fully Integrated Engineer™.
