In this paper, we explore Claudio Ciborra's ideas about the technological object. We do so by contrasting these ideas with analysis by Law and Singleton (2005) who advocate a "methodological radicalism" that moves beyond epistemological uncertainties about the technological object to ontological concerns. Law and Singleton's analysis is comprised of a series of stages that includes fluid objects, which change relatively gently and fire objects, which have more radical discontinuities. This approach is applied to empirical work studying the engagement practices of a large, sophisticated information infrastructure research project, the Digital Business Ecosystem (DBE). At the start of the DBE engagement process, the DBE was an "invisible technology" in the sense that it did not yet exist. Whilst this circumstance is typical at the beginning of innovative technology projects it nonetheless made the process of engagement particularly challenging, presenting the researchers concerned with questions concerning "what" it was that participants should engage with. Drawing on the theoretical insights presented by Law and Singleton the ambiguity of the DBE as an object is brought to the foreground. According to their analysis the DBE appears to have the ontological characteristics of both the fluid and the fire object. In order to address this dilemma we draw upon Ciborra's thinking, particularly around the information infrastructure and Gestell, as a means of reconciling how technologies like the DBE can be both fluid and fire objects. The paper ends with a discussion of the implications of this work on Claudio Ciborra's legacy for the study of information and communications technologies.
