This article reports on the use of "discourse maps" in conjunction with genre and discourse analysis to help teach communicative practices for contract negotiation. Using one map as a baseline to understand the intertextual process of negotiating a contract in communication with business clients and counterpart lawyers, other maps can zoom in and examine the discursive features of email genres, cover letters, and different versions of the contract under negotiation. The type of discourse maps developed in this study can be utilized for task-based writing materials and role-play activities that facilitate the authentic experience of negotiating a business deal.
