International standards for HCI and usability
Did you know that there's a whole set of ISO standards that address usability? Yep, there is...

Standards related to usability can be categorised as primarily concerned with:
- the use of the product (effectiveness, efficiency and satisfaction in a particular context of use)
- the user interface and interaction
- the process used to develop the product
- the capability of an organisation to apply user centred design

The user-centered-design certification that's being talked about is based on these standards.
