This article is an introductory contribution to our Special Issue Reconsidering the Chaîne Opératoire: Towards a Multifaceted Approach to the Archaeology of Techniques . The chaîne opératoire is a central and fundamental concept for archaeological studies that has been fully appropriated and repurposed by several generations of researchers. In this paper, we would like to present some of the points discussed and illustrated by the various articles in this special issue. The aim is to highlight theoretical and practical considerations in various fields, with a diachronic focus. From the biographical approach to the study of artefacts to the challenges of interdisciplinarity through cognitive and sensory approaches, the theoretical discussion is rich and innovative, acknowledging that the chaîne opératoire can be used as a tool for deciphering the complex network of artefacts, environments, and societies of the past and present.
