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 ComplexityComplexitySW systems become complexThe context becomes complexMany usage scenariosHow to conveyInternal structure?Applicability in different contexts?ChangePanta reiRequirements, underlying platform, competitors, market, ...Change ctd.Changes should have limited effectsDo not want to have unknown ripple effectsShould define the envelope of changeWhat is allowed to change without major consequencesGood, old SW engineering principles still apply!Loose couplingHigh cohesionFlexibility as a competitive advantageAT&T vs Sprint
15 The challenges How do you keep track of business requirements? proposals every quarterPrioritize and avoid conflictsHow do you keep track of a very large and complex portfolio of IT-systems ?Several hundred systemsSeveral thousand interfacesHow do you asses the impact of changes ?More than 100 major IS/IT-projects each yearMost projects impact several systems and interfacesHow do you communicate ?The way we do business is deeply integrated into the IT-systems, and changes always impact our processes and opportunitiesIn a large organization knowledge is always spread among several units, no central unit can contain the sum of all relevant knowledgeKOFRitel/TMariusS212Telsis/ABS100Telsis/LKSentaksTelsis/ASSaturnSirius/RSirius/PFHSNumsysSermasSardinTBSKOFAKOF/linkCustomerMasterKundefrontMobilPrivatDatabrønn(IDUN)KURTSAMMaisMiaKuppCCASTIPPTIPSINTRAINRAINSAMOSDosatKlageAvtaleTraneTinoBrevDBRitel/FKatalogRitel/IOPSMasysSymcomNr.tildelNUFSTrastAccarInmarsatFarLafdataTelenettetSSBCAnatrefAdressevaskAladinAlfnetBankutbetgiroYbasBest-NBonusregTrefCMVNSimDatatorgDatexDropsDebo/oobsS12/necosDimanEBBABrasMostSAPTelmaEDIFDSFiberKabellengdeHabitIN-statInfosysKundaxUtenl.avreg.TelefonA B MReginaMbasStarekRuginettNiaplLokalkatalKOSKretaMar.radioLevaxNmasEsopObsregPlanPostdataProduktS656TelekstrafikkResaRutStarSalsaSambaSirius/ASkipsTmos/Smas
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”
