The Capstone Project necessitates the application of the Iterative Design Process in its most comprehensive and sophisticated form. You will fluidly navigate between the core phases of the design cycle β Investigating, Planning, Creating, and Evaluating β constantly refining your work based on continuous feedback, emerging insights, and your evolving understanding of the design challenge.
Detailed Explanation
The iterative design process is a cyclical method that involves several phases: Investigating, Planning, Creating, and Evaluating. Instead of following a linear path, you will revisit these phases multiple times to refine your design. For example, after receiving feedback on your initial prototype, you might go back to the planning phase to adjust your specifications or go back to investigating to gather more user insights. This ongoing loop helps ensure your design becomes more effective and aligned with user needs as you progress.
Examples & Analogies
Think of the iterative design process like making a recipe. The first time you bake a cake, you might follow the recipe exactly, but if it doesnβt taste quite right, you will tweak the ingredients or baking time based on feedback. With each attempt, you refine the process until you get the perfect cake!
