Presentation held by Dr. Stefan Zerbe, ITM at EA Connect Days 2018 in Bonn. While EA (enterprise architecture) is a well-known discipline many business organizations struggle with maturity of their corporate EA practice. But even companies that stopped EA activities in recent years now relaunch EA, in order to tackle challenges resulting from digital transformation, regulatory pressure and increasing IT complexity. This presentation builds on lessons learned from companies working with EA and refocuses the EA value proposition in order to meet business expectations. It highlights the importance to extent EA thinking to business units and explains collaboration modelsto engage both, business and IT architecture specialists as well as managers, in joint architecture activities based on a real project example. From a business-oriented perspective on EA, the presentation picks up the discussion regarding a new agile mindset for EA architects and presents new ideas for tool sets to support EA work in corporations.

use content wisely

applying common knowledge
§ Allow for rehearsal interaction

for e.g. roadmaps
§ See visualizations as products
§ Allow for growth
§ Treat users not as experts -
but as professionals searching
for smart assistance
