The end responsiblity for the "Architecture of the Enterprise" lies with the CEO. This means that Enterprise Architects need to have strong business knowledge in various domains, such as corporate finance, strategy, managerial accounting, organisational behaviour, marketing, investment strategy and economics. And on top of this, strong leadership and management skills.

This means that GEAO should only certify Enterprise Architects who have a business degree (or comparable skills and knowledge gained from experience).
