The Enterprise Architect’s Dilemma

Focus of Enterprise Architecture

The challenges

• How do you keep track of business requirements?

• 50-100 proposals every quarter
• Prioritize and avoid conflicts

• How do you keep track of a very large and complex portfolio of IT-systems ?

• Several hundred systems
• Several thousand interfaces

• How do you asses the impact of changes ?

• More than 100 major IS/IT-projects each year
• Most projects impact several systems and interfaces

• How do you communicate ?

• The way we do business is deeply integrated into the IT-systems, and changes always impact our processes and opportunities
• In a large organization knowledge is always spread among several units, no central unit can contain the sum of all relevant knowledge

... and the answers are:

• Go beyond the technical issues

• “Understand”

• You need to reduce the (apparent) complexity by defining building blocks and abstractions

• ”Simplify”

• You need to build a tool that identifies where and how functionality and data is located

• ”Document”

• You need to build a common language and communication tool

• ”Communicate”
