  7. Methodology Lifecycle Via Heap Map Source: IBM Component Business Model

  8. Component Business Model Dynamic capability is defined as “the firm’s ability to integrate, build, and reconfigure internal and external competences to address rapidly changing environments”. 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, modularization

  9. The 5 Dimensions of a Business Component Resource-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.“ IBM Component Business Model

  11. IT Infrastructure “The hardware, software, and telecommunication/ networking systems or equipment together provide the underlying foundation to support the organization’s goals.”

  13. Characteristics of Architecture Stages

  14. Stages in IT Infrastructure Evolution Mainframe/Mini Computers Personal Computer Client/Sever Computing Internet computing/ Web-based enterprise applications Cloud Computing / Mobile computing 60~70s 80s 90s Late 90s~ Mid 2000s~

  15. Mobile Device

  17. Web-based IT Infrastructure WWW HTTP Internet TCP/IP Software Applications User Interface Browsers DBMS App. Run dynamic business logic components Data Process

  18. Cookie http://en.wikipedia.org/wiki/HTTP_cookie Video: A Guide to Cookies, part of What Do They Know series. Cookie is stored on the client computer not on the Web server Cookies were introduced to provide a way to implement a "shopping cart" (or "shopping basket").

  19. Technology drivers of infrastructure evolution http://www.emc.com/collateral/demos/microsites/idc-digital-universe/iview.htm • 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)

  20. Advancing Rates of Technology (Silicon, Storage, Telecom) Smaller & faster & cheaper

  21. Data Volume 210 =1028

  22. The Internet of Things
