What exactly is the "Chaîne Opératoire"?

Question

Why is this of any significant to Archaeologists or Anthropologists?

Answer 1

chaine operatoire: ordered chain of actions, gestures, and processes in a production sequence (e.g. of a stone tool or a pot) which led to the transformation of a given material towards the finished product. The concept, introduced by Andre Leroi-Gourhan, is significant in allowing the archaeologist to infer back from the finished artifact to the procedures, the intentionality in the production sequence, and ultimately to the conceptual template of the maker.
