Telenor What is Architecture ? How to use Architecture

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 Motivations Two major motivations for explicit architecture Complexity
Change and Complexity 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, ... 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

15 The challenges How do you keep track of business requirements?
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 KOF Ritel/T Marius S212 Telsis/AB S100 Telsis/LK Sentaks Telsis/AS Saturn Sirius/R Sirius/P FHS Numsys Sermas Sardin TBS KOFA KOF/link Customer Master Kundefront Mobil Privat Databrønn (IDUN) KURT SAM Mais Mia Kupp CCAS TIPP TIPS INTRA INRA INSA MOS Dosat Klage Avtale Trane Tino Brev DB Ritel/F Katalog Ritel/I OPS Masys Symcom Nr.tildel NUFS Trast Accar Inmarsat Far Lafdata Telenettet SSBC Anatref Adresse vask Aladin Alfnet Bank utbet giro Ybas Best-N Bonus reg Tref CMVN Sim Data torg Datex Drops Debo/ oobs S12/ necos Diman EBBA Bras Most SAP Telma EDI FDS Fiber Kabel lengde Habit IN-stat Infosys Kundax Utenl. avreg.

16 ... 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”
