This article provides an overview of a research program developed over the
past 20 years to explore relations between everyday practices and technolog
y design and use. The studies highlighted reflect three interrelated lilies
of inquiry: (a) critical analyses of technical discourses and practices, (
b) ethnographies of work and technologies-in-use, and (c) design interventi
ons. Starting from the premise that technologies carl be assessed only in t
heir relations to the sires of their production and use, the authors recons
truct technologies as social practice. A central problem for the design of
artifacts then becomes their relation to the environments of their intended
use. Through ethnographies of the social world, the analyses focus on just
how social/material specificities are assembled together to comprise our e
veryday experience.
