5 5 Telenor What is Architecture ? How to use Architecture

6 6 What is architecture ? Efficient code ? Well structured code ? Using the right languages and/or tools ? Well formed and flexible data models ? Choosing the right suppliers of software ? To have a cost effective portfolio of systems ?

7 7 Motivations Change ctd. –Changes should have limited effects –Do not want to have unknown ripple effects –Should define the envelope of change –What is allowed to change without major consequences –Good, old SW engineering principles still apply! –Loose coupling –High cohesion –Flexibility as a competitive advantage –AT&T vs Sprint Complexity –SW systems become complex –The context becomes complex –Many usage scenarios –How to convey –Internal structure? –Applicability in different contexts? Change –Panta rei –Requirements, underlying platform, competitors, market,... Two major motivations for explicit architecture –Change and Complexity

12 12 Telenor What is Enterprise Architecture ? How to use Architecture

13 13 The Enterprise Architect’s Dilemma ©May 2007, “Role Overview: The Enterprise Architecture Professional In 2007”

14 14 Focus of Enterprise Architecture ©May 2007, “Role Overview: The Enterprise Architecture Professional In 2007”

15 15 The challenges 1.How do you keep track of business requirements? – proposals every quarter –Prioritize and avoid conflicts 2.How do you keep track of a very large and complex portfolio of IT-systems ? –Several hundred systems –Several thousand interfaces 3.How do you asses the impact of changes ? –More than 100 major IS/IT-projects each year –Most projects impact several systems and interfaces 4.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

16 16... and the answers are: 1.Go beyond the technical issues –“Understand” 2.You need to reduce the (apparent) complexity by defining building blocks and abstractions –”Simplify” 3.You need to build a tool that identifies where and how functionality and data is located –”Document” 4.You need to build a common language and communication tool –”Communicate”

17 17 Enterprise Architects in Telenor... Translate business requirements into solutions –In large projects spanning up to 50 different systems Develop a roadmap and different migration scenarios for the IS portfolio –In cooperation with strategy and top management Evaluate the impact of a transition to IP-based telephony on the support systems –From customer to network support systems –Both fixed and mobile Build a common information model for customer-centric systems –Next step: Convergence Evaluate all major projects before investment decision –Architecture and IT estimates –Appr. 100 projects per year
