This document discusses two views of discourse structure - as a product and as a process. It describes how discourse can be analyzed by looking at its hierarchical rank structure with different levels like lessons, transactions, exchanges, moves and acts. It also examines turn-taking in conversations and how speakers negotiate turns through mechanisms like pauses and intonation which can vary between cultures. Finally, it characterizes conversation as a mutually constructed process where participants feel their way forward together through established patterns and repair.
