The chapter sets out the organisation of the guide. It comprises the relations between the initial UX approaches description, the UX practitioner source material and the UX guide notes. First, the UX guide notes link to the initial UX approaches description. Second, the UX guide notes link to the practitioner UX approaches contributions. Last, the UX guide notes link the UX approaches description and the UX practitioner source material by identifying descriptors in the latter absent from the former. The practitioner contributions are ordered by level of detail—from less to more. They are—Cummaford, Blyth, Sinclair and Timmer.
