Dialogue-based Design for Multi-Channel Interactions

Lightweight design processes and usable methodologies are increasingly being recognized as “must” requirements for effective design of complex interactive applications. In particular, these requirements imply different factors: • It must be easy to teach the design methodology and model to someone (a practitioner, especially): professionals do not have time and resources to invest for learning new methodologies; one of the success factors of “Entity Relationship” (probably the most successful design model, ever) stems from the fact that it was very easy to transmit its basic concept. • It must be possible to use the design model for brainstorming and for discussing ideas (among developers, with stakeholders, with possible users, etc.): it is of little use to have a design methodology (model) capable of representing only fully developed solutions. • It must require little time to write down design ideas: developers do not like to spend too much time in preliminary activities. • It must be possible to move, smoothly, from a general design, to more detailed design, without need for excessive reworking and without need for completeness; in other words, even an incomplete design document must be useful and understandable.
