"Since 2003, more and more authors using the term EA explicitly in their publications, Most of the newer contributions are coming from an academic background. Especially after 2005, a lot of consultancies and IT-companies are adopting their products and strategies to an extended architectural understanding hence Enterprise Architecture... After 2004-2005 a lot of companies started to use the term EA and since then have connected it somehow to their products and strategies a huge amount of superficial marketing material has been distributed. Consider the maturity and the focus of the contributions there is no topic or even a theory in the discipline of EA. Almost half of the approaches discussed in the papers are still coming from low maturity level (Concept Phase) in the context of readiness to be used in an organization. Only a third of the authors are delivering some kind of best practice (Implementation/Adoption). Differentiating the focus of EA-authors there are two specific topics only (EA-Frameworks and Enterprise Modeling) the majority is dealing with rather general aspects."
