"Once the product's task is known, design the interface first; then implement to the interface design"

This quote by Jef Raskin recommends that when designing a product, the interface must be the primary step at the same time. This implies that the interface should be designed before the product is carried out. The interface is the user's point of contact with the product, so it is necessary to develop it in a way that is user-friendly and easy to utilize. By creating the interface initially, the item can be customized to the user's needs and preferences. This will guarantee that the product is as easy to use as possible. Additionally, developing the interface initially will assist to guarantee that the item is executed correctly and efficiently. By designing the user interface initially, the item can be tailored to the user's requirements and choices, and the implementation process can be structured. This quote emphasizes the significance of designing the user interface initially in order to develop a successful item.
