Agile modeling of Enterprise Arcitecture

I talked about classic modeling enterprise architecture (EA) at the past Analyst Days 2016, showed an example of EA by using Archimate. After that I heard many comments that the classical modeling of EA is very difficult, long and models hard to support. In this talk I'll share my thoughts - how to facilitate the description of EA and implement in Agile:

• A minimum set of required Archimate diagrams .
• Where and how to use Archimate diagrams in Agile?
• Archimate + UML - how to combine them?
• The implementation of Agile principles in EA development.
