Design methods are structured approaches used to solve problems and create effective solutions in various fields, including architecture, graphic design, and product development. These methods often involve research, brainstorming, prototyping, and testing to ensure that the final design meets user needs and expectations. Common design methods include user-centered design, which focuses on understanding the needs of the end-user, and iterative design, which emphasizes continuous improvement through repeated cycles of testing and feedback. By employing these methods, designers can create more functional, aesthetically pleasing, and user-friendly products and services.
