We recommend using Compendium software for this type of mapping, as it allows you to extend, reuse and share IBIS maps far more easily than with hand-drawn maps or indented text IBIS (itIBIS) structures. Compendium was initially developed in Verizon research labs as a next generation version of the QuestMap product. QuestMap was the first commercially available software that supported the IBIS (Issue-Based Information System) methodology, as used in Dialogue Mapping. Learning Compendium requires a bit of time investment, but we believe it is the best software currently available to do this kind of mapping. Visual Understanding Environment. Mind Mapping.
