Boundary work

Boundary work is the social and epistemic labor required to maintain the distinctions that make collaboration possible — the work of deciding what counts as inside a system and what counts as outside, what is shared and what is proprietary, what is negotiable and what is fixed. It is the invisible infrastructure of interdisciplinary practice: the meetings, the translations, the compromises, and the occasional conflicts that produce and maintain boundary objects. Without boundary work, boundary objects decay into empty rituals or are captured by single communities.

The concept, developed in science and technology studies, reveals that boundaries are not discovered but constructed — and that the construction is political. When a software team declares that "the API is the boundary," they are not describing a natural fact; they are performing boundary work that allocates responsibility, authority, and blame. The study of boundary work connects to epistemic boundaries in philosophy: the limits of what a community knows, and the social mechanisms that police those limits.
