Heuristic Evaluation

a group of experts independently scrutinize the interface and evaluate each element of the interface against a list of commonly accepted standards/ usability principles--heuristics
- heuristic evaluation is used when there isnt any access to users.
- can be used to evaluate prototypes/ mockups in the early stages of product design lifecycle

- 3 to 5 experts will be able to detect more than 75% of the problems
- different experts will find different problems
- its inexpensive

- its crucial to recruit properly trained & qualified experts
- this technique is subjective and might raise false alarms


phases:
- prevaluation training : domain knowlegge inputs and scenarios can be given to the experts
- evaluation is done independently and findings are compared
- severity of every problem is assigned. problems are prioritised
- the evaluation report is discussed with the ui team members.

  1. Found a lot of useful info on your site about Product Design - thank you. Haven't finished reading it yet but have bookmarked it so I don't lose it. I've just started a Product Design blog myself if you'd like to stop by

  2. Do you have an Rss feed to subscribe to. If can ever get my aggregator to work I'll be set. It may be because I'm spending so much time reading about ##KEYWORD## . It's been an obsession for the last year now. Sorry, I'm thinking aloud and probably boring you with prototyping thoughts.

  3. Is this blog feed live? I'd like to subscribe to it using my aggregator. It's possible that my site rapid prototyping can get your feed automatically so I can keep up with our design and cnc posts here.

  4. Do you have an Rss feed to subscribe to? Im learning how to install an Rss reader and I'm learning. But it seems that I've been juggling the learning of design prototyping and development in general. I'll get it working though.
