Quick questions on Ideation and sketching: O-Level Design Studies

Brainstorming is rapidly producing as many ideas as possible, alone or in a group, without criticising them. The rules are quantity over quality at first, no judgement, and building on others' ideas. It is a fast way to fill the page with possibilities, including the strange ones that sometimes lead somewhere good.

A mind map starts from a central word or problem and branches outward to related ideas, then to sub-ideas. The branching structure sparks connections you might not reach in a list and opens multiple directions at once, making it useful for exploring a theme broadly before sketching.

Thumbnails are small, quick, rough sketches, often many to a page, used to capture and compare ideas fast. They are deliberately small and unpolished so the designer focuses on the idea, not the drawing, and can explore dozens of variations in minutes. Thumbnails are the visual equivalent of brainstorming.

A sketch alone shows what an idea looks like; annotation explains how and why it works. Good annotation notes the reasoning behind choices (why this shape, colour or feature), how the idea functions or is used, the materials, and its strengths and weaknesses. In Design Studies, annotation is where marks live, because it makes the designer's thinking visible to the assessor.
