What Makes UCD Different

User-centred design (UCD) was introduced in A2.1.1; here we look at where it came from and how its process runs.
The term was coined in the 1980s by cognitive scientist Donald Norman, whose book The Design of Everyday Things argued that good design builds users' needs and capabilities in from start to finish, rather than adding features for their own sake.
Unlike traditional design, where a product is developed in isolation and meets its users only at launch, UCD consults users at several points and re-tests the design until it genuinely meets their needs.
UCD builds in only the functions users actually need, since unwanted features raise cost and complexity, which is why a wide-audience interface like an ATM stays standardised.

The Five Stages of the UCD Process

UCD is usually described as five stages, shown here through a team developing a new reusable water bottle:
Research
1. Define the problem and the criteria the design must meet, observing and interviewing students to see how they carry, use, and clean their bottles.
