This document summarizes Lecture 3 of a design course. It is divided into three parts: creation, prototyping, and production. The creation section discusses techniques for generating ideas like brainstorming, selecting the best solution, and illustrating concepts as sketches. Students are then asked to complete an individual assignment by sharing sketches of at least two design ideas with five sketches each for instructor critique. The prototyping and production sections will cover transforming concepts into works and taking the design to audiences.
