The Social Life of Standards reveals how political and technical tools for organizing society are developed, subverted, contested, and reassembled by local communities interacting with standards created by others. The authors investigate biomedical, agricultural, and other cases to show how inconsistent implementation of standards in the real world runs up against the non-negotiable criteria presupposed by external forces. To solve these problems, they propose a new, reflexive process that involves local engagement at every stage in the production and application of standards.
