A/B Testing

Full Title or Meme

A stratagem for comparing two User Experience options by running both in parallel and comparing results.

Context

The difficulty in determining the impact of changes on the User Experience at a Web Site has lead to a range of techniques, the easiest to implement being the simple expedient of just enabling any proposed, and pretested User Experience as a live version of an already deployed Web Site, or other rendering of a User Experience. Under the assumption that pre-testing has shown no problems, the best approach is to introduce it to a small of Users and ask for feedback from the user or just to monitor their reactions to the site. The larger the change, the more likely to take a while before the user response can be fairly evaluated.
