Product design involves several main stages including research, concept development, design, and production. The design process starts with doodling sketches to develop the initial product concept, followed by thinking sketches to refine the idea. Technical sketches are then created using views and sections to communicate how the product will work. Presentation sketches further refine the design visually. Emotive sketches provide a final emotional rendering of the product for clients.
