In this paper we describe the design of a turn manager for deployment in artificial conversational agents, using the Harel statechart formalism. We show that the formalism's support for concurrent interrelated processes allows a modular design, producing three smaller statecharts responsible for the turn taking logic. The logic of the turn manager is inspired by a well-known turn management model for human-human conversation.
