Demystifying Usability
2004

Abstract:

What you buy or 'buy into' influences how you think about something and how you represent that information in your mind is what cognitive scientists refer to as an 'internal representation'. Whether you buy usability services or not, at some point along the way I am sure you will or have encountered 'methodology madness', and maybe you don't even know it.
