The chapter sets out the organisation of the guide. It comprises the relations between the initial UX case study description, the UX practitioner source material and the UX guide notes. First, the UX guide notes link to the initial UX case study description. Second, the UX guide notes link to the practitioner UX case study contributions. Last, the UX guide notes link the UX case study description and the UX practitioner source material by identifying descriptors in the latter absent from the former. The practitioner contributions are ordered by completeness—from less to more. Both case studies are by Sinclair.
