3. Enterprise Architecture - Objectives for Today Not to be a boring re-run To answer the simple question – Did it work for you? To use language and arguments which non experts can understand To present a personal view in the context of the opportunities that EA might bring at an industry and European level To do that by: Describing what I think EA is Presenting the characteristics of EA of particular value and which might be relevant in persuading Airspace Users to engage Discussing what engagement might require from Airspace Users To consider potential next steps

10. Enterprise Architecture - Summary Service Orientated Enterprise Architecture is a proven approach and has now been shown as applicable to ATM It is beneficial within an individual stakeholder business but seems particularly useful in describing a Business Enterprise dependent on relationships between a number of disparate stakeholders To be successful it requires the active involvement of all stakeholders.
