Human-Centered Design Considered Harmful

Why do these devices work so well? The basic reason is that they were all developed with a deep understanding of the activities that were to be performed: call this Activity-Centered Design. Many were not even designed in the common sense of the term, rather, they evolved with time. Each new generation of builders slowly improved the product upon the previous generation, based on feedback from their own experiences as well as from their customers. Slow, evolutionary folk design. But even for those devices created by formal design teams, populated with people whose job title was “designer,” these designers used their own understanding of the activities to be performed to determine how the device would be operated. The users were supposed to understand the task and to understand the designers’ intentions.
