Refers to a concept promulgated by the National Association of Higher Education Systems (NASH), on behalf of its network of 51 higher education systems working collaboratively to address critical issues in higher education. The concept is founded in the recognition that systems working together are greater than the sum of their parts.  The core of their commitment is to leverage their power to convene and facilitate, along with their governing and policy-making authority, to build collaborations to support students and campuses—rather than trying to mediate competitive actions.
