Actor Network Theory (ANT)

ANT is often accredited as the work of Michel Callon, Bruno Latour, and John Law (Callon 1986, 1999; Latour 1987, 1988, 1999; Law 1999; Sidle & Warzynski 2003; Sismondo 2004; Tatnall & Burgess 2004; Tatnall & Lepa 2003). ANT deals with (Bardini 1997):

“… progressive constitution of a network in which both human and non-human actors assume identities according to prevailing strategies of interaction. Actors’ identities and qualities are defined during negotiations between representatives of human and non-human actors. The most important of these negotiations is ‘translation‘, a multi faced interaction in which actors:

Construct common definitions and meanings

Define representatives

Co-opt each other in the pursuit of individual and collective objectives.”

The translation process consist of four stages (Callon 1986):

  1. Problematisation. Key actors attempt to define the problem and roles of other actors to fit the proposed solution, which was made by the key actors.
  2. Interresment. Processes that attempt to impose the identities and roles defined in problematisation on other actors.
  3. Enrolment. A process where one set of actors (key actors) imposes their will on others. The other actors will be persuaded to follow the identities and roles defined by the key actors. This will then lead to the establishment of a stable network of alliances.
  4. Mobilisation. This is where the proposed solutions gain wider acceptance. The network would grow larger with the involvement of other parties that were not involved previously. This growth is due to the influence of actors.

When using ANT to investigate IT adoption, a researcher would focus on issues such as network formation, human and non-human actors, alliance, and network build up (Sismondo 2004; Tatnall & Burgess 2004). Stronger alliances would be likely to influence the decision to adopt or reject IT. In conclusion, ANT recognises that adoption of innovation is initiated by individuals who build a network of individuals (in the form of an organisation) and nonhumans (machine, tools, etc.) to adopt innovations. ANT is different from DOI in several ways:

  • It breaks the communication into stages (of translation).
  • It considers the details of “resistance” (anti-program).
  • It treats non-humans as actors.
  • It explains success and failure with the same model.

ANT was originally developed to explain the diffusion of science into society (for example the idea of pasteurisation in Latour 1988). It is similar to Rogers’s DOI. The difference is that Rogers’s DOI viewed the diffusion as merely a communication process, while ANT viewed diffusion of innovation as involving a political game where an actor (who wants to spread the innovation) builds a network that will use the innovation.

The use of ANT in explaining the adoption of innovation is still in its early stage. Some examples are the works of McMaster (McMaster 2001; McMaster, Vidgen & Wastell 1997) and Tatnall (Tatnall & Burgess 2004; Tatnall & Lepa 2003). In those studies, the process of translation was believed to be richer and deeper in that it acknowledged the intertwining and inseparability of technical and social issues. Ciborra has also used ANT to study the management of IT infrastructure and knowledge management (Ciborra & Hanseth 1998a, 1998b; Ciborra & Patriotta 1998; Hanseth, Ciborra & Braa 2001). Development of knowledge management and management of IT infrastructure are considered to be political processes, where different stakeholders try to win power and spread their “ideology”.

ANT is an example of a theory to explain how different stakeholders in an organisation try to spread their ideas to the other stakeholders and influence them to accept the ideas. From the ANT perspective, an actor would build a network of power to overcome other networks of power so he or she could win and impose their ideas. At the end, the actors would use the network to achieve their own goals. In the context of adoption of innovation, the ANT perspective could be used to show how different actors spread their ideas (innovation) to be adopted by others through the development of a network. When their ideas (innovation) are accepted by the other stakeholders (the development of a network), the actor could use the network to achieve his or her own goals.

  1. Your clear stages of translation are very interesting. I had a lot of trouble in defining “translation” in Latours work, especially when I had to make the distinction with another frequently used term “transformation”. Ultimately I think that the biggest problem is Latours metaphysics. Because, the most common used meaning of “translation” in Latours work is: translation is the connection of different actants by using all kinds of tactics (cfr Sciencen in Action, pp. 108-120) to conquer certain goals and interests of other actants. “Transformation” is a process of change in which “change” is every variation in relations.
    But, according to Latours metaphysics every actant is a network and its essence is equal to all its relations. So every change in relations makes a new actant. Therefore, every translation is also a transformation that results in a new actant.
    Therefore it seems to me that translation is a specific form of transformation, in which only goals and interests are considered? While transformation is a general noise in every movement, every association, every event (cfr. Reassembling the Social, p. 173). Did you interpret Latours work in a similar way?
    Kind regards,
