In Chapter 6, Dialog Mapping: Reflections on an Industrial Strength Case Study, Jeff Conklin describes how one of the most influential argumentation schemes dating back to the 1970s, Kunz and Rittel’s Issue-Based Information System (IBIS), has been developed into a facilitated CSAV technique called Dialog Mapping. Dialog Mapping (like van Gelder’s industrial case study) introduces the facilitator as a key player who adds value through expertise in argument mapping and group process. Conklin then presents what is probably the longest-term case study available of CSAV adoption in an organization, reflecting on the lessons that can be distilled from a company that has used the QuestMap tool continuously for the last decade to support synchronous and asynchronous work.
