Human-centred design

Human-centred design is an approach that grounds design decisions in the needs, tasks and environments of the people who will use the result, and validates against them rather than against opinion.

It is defined as a standard, not just a philosophy. DIN EN ISO 9241-210 sets out principles and required activities: understand the context of use, specify the requirements, produce design solutions, and evaluate against the requirements, iterating until they are met.

Human-centred or user-centred

The terms are used almost interchangeably. Where a distinction is drawn, human-centred is the broader one, taking in people affected by the system who never use it directly: a patient whose treatment depends on a clinician’s interface, a member of the public near an automated vehicle. User-centred stays with the operator.

ISO 9241-210 replaced the earlier 13407 standard and uses “human-centred” deliberately for that reason.

Why the standard matters commercially

In regulated, industrial and public-sector procurement, a process that can be named and audited is worth more than one that cannot. Citing ISO 9241 turns “we did user research” into a defined set of activities with defined outputs, which is a different conversation with a client’s quality department.

In practice

The part teams most often skip is the first: context of use. Requirements written without it describe a product for an imagined user in an imagined environment, and every later activity inherits that error.
