Good design is more than meets the eye. The visual part of a design – the look and feel – is only the tip of the iceberg. Beneath the surface lies the foundation of a successful design: a user centred design process. It is a development cycle which takes into consideration what users really need and makes adjustments by exploring, testing and tuning the design until these needs are satisfied. The result of this is a high level of usability: the design is effective, efficient, engaging and easy to learn. The process can be applied to all design practices that have the aim to provide a good user experience. This includes web design, interface design, product design, editorial design, urban design, wayfinding, service design and architecture.
