Rams argues that the appearance of a product is closely connected to how well it works. A device that is visually confused, overloaded or poorly organised can make its purpose harder to understand and its operation less intuitive. In this sense, aesthetic order is not separate from function; it helps communicate how a product should be used.

He also suggests that visual harmony has an emotional role. A product that feels coherent and understandable can support a more positive relationship between the user and the object. This does not mean that appearance should take priority over practical performance. Rather, Rams presents usability, clarity and aesthetic quality as parts of the same design task.

The quotation reflects a broader view of design in which form should support function while also shaping how people experience and relate to everyday products.
