The situation

Week 15, Monday 8 February 2027. Lesson 3 rehearsed the six designs every reviewer expects. Gareth now hands over four that stretch a candidate: voice, research, moderation and recommendations.

Two are Joel's ideas: Tallis's 54,000 store staff, who have no desks, phoning the helpdesk, and suggested articles on the Ask home page. Two are classic prompts. Every number Gareth sets is illustrative; prices are course-guide/02's snapshot, checked 18 October 2026.
