Subjects

Wireframing and Prototyping

Covers the low/mid/high fidelity spectrum and what question each level is built to answer, why higher fidelity is a tradeoff rather than a quality ladder, the cost-of-change curve that justifies validating structure before polish, fidelity vs. interactivity as two separate axes, how to choose a fidelity/interactivity combination for a given situation, the prototyping tools landscape framed for interview judgment rather than tool trivia, the risk of designing directly in code or a high-fidelity tool, and how to run the classic whiteboard sketching exercise.

Personas, Journey Maps, and Jobs-to-be-Done

Covers proto-personas vs. research-based personas and the 'persona theater' trap, the Says/Thinks/Does/Feels empathy map, journey map structure with a worked e-commerce example, Jobs-to-be-Done and the Christensen/Moesta milkshake study with its functional/emotional/social dimensions, service blueprints and the frontstage/backstage/support-process distinction, and a decision framework for picking the right synthesis tool.
