Sammanfattning	Sociotechnical systems analysis, developed by the historian of technology Thomas P. Hughes, studies large technological systems—electric power, telephony, transport—as a 'seamless web' in which physical artefacts, organisations, scientific knowledge, laws, and people are woven together. Drawing on his study of electrification in Networks of Power and his model of system evolution, the method locates the system's reverse salients, follows the work of system builders, and traces how a system acquires momentum and passes through characteristic phases of growth.	Actor-Network Theory analysis treats society and technology as a single woven fabric, mapping how heterogeneous human and non-human actors—engineers, scallops, documents, machines, regulators—are linked into networks through a process of translation. Rather than explaining technical outcomes by appeal to pre-given social categories, ANT follows the actors themselves and describes how durable arrangements are assembled, stabilised, and sometimes undone.
