Summary	The infrastructure studies method, developed by Susan Leigh Star, Geoffrey Bowker, and Karen Ruhleder, studies the normally invisible relational systems—standards, classifications, pipes, protocols, and installed bases—on which modern life silently depends. Its signature move is 'infrastructural inversion': deliberately foregrounding the background, treating the taken-for-granted substrate as the object of analysis, and reading its standards, classifications, and breakdowns to understand how it shapes work, knowledge, and lives.	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.
