The ongoing evolution and enrichment of the Higher Education Reference Models would be impossible without the warm global collaboration between the CAUDIT HERM Working Group, our colleagues in the United Kingdom through UCISA, other European colleagues through EUNIS, and our North American colleagues through EDUCAUSE. The value and usefulness of the HERM is enriched, amplified, and increased enormously by the expertise, engagement, and generous contributions of the worldwide higher-education enterprise architecture community.
