Peter Morville, the author of
Information Architecture for the World Wide Web and
Ambient Findability is also known to have created the
User Experience Honeycomb diagram. Even though his honeycomb is over two years old, it's still used by Peter at presentations:

I always thought that his diagram had a strong appeal, but also that it was lacking something. To my surprise, I found the diagram became much better after re-structuring it. It is kind of ironic that the work of one of the greatest information architects in the world wasn't structured ideally from the beginning. But then again, I might be completely wrong. Anyways, I put the facets in a different order and removed the honeycombs:

Why the new order? Simple, now the facets are in order of experience. The rationale for the order is the following:
Findability: It's first, to quote the inspiration of this post "you can't use what you can't find"
Accessibility: Maybe a new quote, "you can't use what you can't access"
Desirabiliy: You see the interface before you use it.
Usability: You have to be able to use something to do something with it
Credibility: You have to trust something before actually commiting to solving a task with the service
Usefulness: Usefulness is last, because a user forms an opinion about usefulness when he leaves, hopefully after completing his task.
Value: value is the result of the user experience and not a facet of it.
It is my humble opinion that the honeycomb is more descriptive as a process than as a honeycomb. Although, the insight would never have came had it not been for the
original.
