On enterprise architect

Quote from The Role of the Enterprise Architect.

one of the fundamental requirements for being a successful EA is the ability to lead without actually owning anything: If you don't have good leadership skills, the rest of it fundamentally doesn’t matter... If you do not lead and do not take the risk to lead, the transformation won’t occur. One of the barriers for the profession today is that many architects are not prepared to take the risk of leadership.

The authority of an architect ultimately comes from their ability to articulate a compelling value proposition for architecture in general, for specific architect in a specific situation... This is probably one of the biggest problems that architects coming from a technical background have. They'll tell you about features and functions but never get around talking about benefits.
