No, I have not suddenly started to question an approach which I have pioneered for more than three decades.
What I am doing is reflecting a discussion currently underway in the International Standards committee considering the revision of ISO 9241 part 11, which defines usability.
Don’t worry, we don’t intend to change the definition in any way that most people would notice. Standard-makers love arguing about fine detail, so there may be some tweaking of the wording in due course.
The core definition will remain the same but we’d welcome some input from Econsultancy’s members about how we describe the outcome of using user-centred design.
