Tensions across the scales: planning infrastructure for the long-term

In designing information infrastructure participants are planning for the long-term. The notion of infrastructure evokes images beyond 'a proof of concept,' a 'prototype' or an isolated 'application'; it is intended to be a persistent, ubiquitous and reliable environment. However, in implementing such projects participants confront multiple difficulties such as securing sustained funding, supporting maintenance and integrating new technologies. Based on cross-case ethnographic analysis this paper traces nine tensions identified by participants as they endeavor to transition from short-term projects to long-term information infrastructure. We explore three core concerns framed by actors: motivating contribution; aligning end-goals; and designing for use. These concerns have unique implications for each scale of infrastructure: institutionalization; the organization of work; and enacting technology.
