The basic assumption of the dynamic capabilities framework is that today’s fast changing markets force firms to respond quickly and to be innovative. Agile, sense and respond, reconfiguration, modularizationEA and IT Infrastructure - 9 © Minder Chen, 1995-2011The 5 Dimensions of a Business Component•IBM Component Business ModelResource-Based ViewDaft (1983) says: "...firm resources include all assets, capabilities, organizational processes, firm attributes, information, knowledge, etc; controlled by a firm that enable the firm to conceive of and implement strategies that improve its efficiency and effectiveness.“EA and IT Infrastructure - 10 © Minder Chen, 1995-2011Heat MapEA and IT Infrastructure - 11 © Minder Chen, 1995-2011IT Infrastructure •“The hardware, software, and telecommunication/ networking systems or equipment together provide the underlying foundation to support the organization’s goals.”EA and IT Infrastructure - 12 © Minder Chen, 1995-2011IT Infrastructure•Cost allocation Source: CISR Working Paper #329EA and IT Infrastructure - 13 © Minder Chen, 1995-2011EA and IT Infrastructure - 14 © Minder Chen, 1995-2011Stages in IT Infrastructure EvolutionMainframe/Mini ComputersPersonal ComputerClient/Sever ComputingInternet computing/Web-based enterprise applicationsCloud Computing / Mobile computing 60~70s80s90sLate 90s~Mid 2000s~EA and IT Infrastructure - 15 © Minder Chen, 1995-2011Web-based IT Infrastructure HTTPTCP/IPWWWInternetRun dynamicbusiness logic components Software Applications DBMSBrowsersUserInterfaceDataProcessApp.EA and IT Infrastructure - 16 © Minder Chen, 1995-2011Mobile DeviceEA and IT Infrastructure - 17 © Minder Chen, 1995-2011Mobile ComputingSource: 2011/9/28EA and IT Infrastructure - 18 © Minder Chen, 1995-2011Technology drivers of infrastructure evolution•Moore’s law and micro-processing powerComputing power doubles every 18 months/2 yearsNanotechnology: May shrink size of transistors to width of several atomsContrary factors: Heat dissipation needs, power consumption concerns•Law of Mass Digital StorageThe amount of data being stored each year doubles•Metcalfe’s Law and network economicsValue or power of a network grows exponentially as a function of the number of network membersAs network members increase, more people want to use it (demand for network access increases)http://www.emc.com/collateral/demos/microsites/idc-digital-universe/iview.htmEA and IT Infrastructure - 19 © Minder Chen, 1995-2011Advancing Rates of Technology (Silicon, Storage, Telecom)Smaller & faster & cheaperEA and IT Infrastructure - 20 © Minder Chen, 1995-2011Data Volume 210 =1028EA and IT Infrastructure - 21 © Minder Chen, 1995-2011EA and IT Infrastructure - 22 © Minder Chen, 1995-2011The Internet of ThingsEA and IT Infrastructure - 23 © Minder Chen, 1995-2011EA and IT Infrastructure - 24 © Minder Chen, 1995-2011CPM: cost per thousand page impressions.http://en.wikipedia.org/wiki/Cost_per_impressionEA and IT Infrastructure - 25 © Minder Chen, 1995-2011Platform Continuum•Bring your own machines, connectivity, software, etc.•Complete control•Complete responsibility•Static capabilities•Upfront capital costs for the infrastructure•Renting machines, connectivity, software•Less control•Fewer responsibilities•Lower capital costs •More flexible•Pay for fixed capacity, even if idle•Shared, multi-tenant infrastructure•Virtualized & dynamic•Scalable & available•Abstracted from the infrastructure•Higher-level services•Pay as you goOn-PremisesServersHosted ServersCloud PlatformEA and IT
