Idempotent Design: When Order Shouldn't Matter
The article discusses the concept of idempotent design, emphasizing that user interactions should not depend on the order of inputs. It contrasts this with systems that require a specific sequence, which can lead to user frustration. The author uses examples from fast-food drive-thrus to illustrate how design can either facilitate or hinder user experience based on how it handles input order.
