I'm working for my final project. In the analysis, i have to choose one model to be used as a reference implementation. So, which is more relevant to be implemented, Nielsen's Model of Usability or Eason's Model of Usability? and which is the most widely used?

Please, explain to me the reason. I need some reference too.

  • Does it really matter for your project which model you use? I don't think so. Your tasks is to choose one and analyze your implementation using it. – dnbrv Jun 22 '12 at 5:11

    @dnbrv of course. I need to know which models are most widely used so I can find out the advantages of the model is compared to other models. – Livin Jun 22 '12 at 5:24
  • you should link to the actual source if you're talking about it. If the source is huge and you need to pay for it, you should at least use the examples that grab your attention the most and comment on them :) – edgarator Jun 22 '12 at 7:45

    @JeroenEijkhof We're happy to help out with questions, and the comments here show that for around 10 hours this question was left open awaiting an update - just providing sources or a summary about the two models would probably suffice - but this is yet to happen so the question has been temporarily closed to new answers while the OP can source the references / summaries needed to improve the question. – JonW Jun 22 '12 at 15:55


Neilsen has been pretty active in the field over the last 20 years. (Mr ?) Eason seems to have written about this in 1988 - and then not been seen since.


The ISO definition is the most common 'model' of what usability is:
