32. Shadowing: Following a user through their entire day to understand context.
33. Requirements Workshop: A structured, intense session (often 1-3 days) to drive consensus quickly.
34. Storyboarding: Visually illustrating the sequence of user interactions (like a comic strip).
35. Prototyping (Low-Fidelity): Paper sketches or wireframes to validate concepts cheaply.
36. Prototyping (High-Fidelity): Clickable, interactive mockups for usability testing.
37. Reverse Prototyping: Starting with an existing system and removing features to find the core need.
38. Document Analysis: Mining requirements from legacy manuals, contracts, or regulations.
39. Interface Analysis: Understanding the touchpoints between this system and external systems.
