an information infrastructure is defined by ole hanseth (2002) as "a shared, evolving, open, standardized, and heterogeneous installed base"
the notion of information infrastructures, introduced in the 1990s and refined during the following decade, has proven quite fruitful to the
the concept of information infrastructure (ii) was introduced in the early 1990s, first as a political initiative (gore, 1993 & bangemann, 1994), later as a more specific concept in is research. for the is research community, an important inspiration was hughes′ (1983) accounts of large technical systems, analyzed as socio-technical power structures (bygstad, 2008).
information infrastructure, as a theory, has been used to frame a number of extensive case studies (star and ruhleder 1996; ciborra 2000; hanseth and ciborra 2007), and in particular to develop an alternative approach to is design: "infrastructures should rather be built by establishing working local solutions supporting local practices which subsequently are linked together rather than by defining universal standards and subsequently implementing them" (ciborra and hanseth 1998). it has later been developed into a full design theory, focusing on the growth of an installed base (hanseth and lyytinen 2008).
information infrastructures include the internet, health systems and corporate systems.
