Sean has worked within BT for six years in technical disciplines and technical assurance roles.  He has developed methods and approaches for delivery of complex technical projects and programmes ranging from simple switched LAN transformation (140,000+ user ports) to IP Telephony and IP Contact Centre solutions delivery.  He has experience of developing new methods for technical assurance and most recently led a proof of concept exercise in enterprise modelling for BT, working closely with Avolution to demonstrate the effectiveness and potential of enterprise modelling.  He has a long history of applying industry standards including ISO9001, ITIL, BS7799, PRINCE2 and most recently TOGAF in a systems engineering and integration context.  He has worked in all aspects of IT for more than twenty years and now heads up a new technical assurance function underpinning a large government IT transformation programme within BT.

Presentation
CASE STUDY: Enterprise Modelling at BT

BT client programmes can involve hundreds of thousands of users, from a multitude of locations, concurrently requiring access to critical business services, from a single converged solution.  Clearly, a well documented architecture of the solution is a step in the right direction, but to be successful the enterprise architecture approach must also include some advanced analytical techniques.  In this case study we will show how BT is applying the advanced techniques of Impact, Scenario and Trade-off analysis (based on TOGAF) and a metrics-based architecture method (based on ABACUS) to engineer an optimal solution for conflicting metrics such as performance, reliability, cost and agility.
