What are annotated detail sketches?Show answer
The main tool of development is the annotated sketch. The designer draws parts of the idea in detail (the joints, the compartments, the mechanism) and writes notes explaining each decision: why this size, this material, this method. Annotation turns a picture into a worked-out design and forces the designer to think through problems on paper, where they are cheap to fix. Good development sketches explore alternatives and show reasoning.
What are modelling to develop in three dimensions?Show answer
Flat sketches hide problems that appear in three dimensions. Modelling, with card, foam, clay or simple prototypes, lets the designer test size, proportion, fit and function physically. A slot that looks fine on paper may be too small for a real phone; a model reveals it. Modelling at the development stage catches such problems before time is spent on a final prototype.
