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.

  • 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)
