Benefits and problems of faceted classification

Benefits of faceted classification:

  1. Do not require complete knowledge of an individual items
  2. Do not require knowledge about relationships of items
  3. Classes are hospitable, can accomodate new entities easily
  4. Classes are flexible
  5. Classes are expressive
  6. Classes can be ad-hoc and free-form
  7. Clases allow many different aspects on and approaches to the items

Major problems of faceted classification:

  1. Choosing the right facets
  2. Lack of ability to express relationships between facets
  3. Lack of ability to visually express the scheme

The NEW user experience …

… goes beyond mere usability.

“We need to create an experience that motivates action.”

In practice: “Though the cardinal rule of usability is to make it simple, it’s possible to make a design too simple, thereby causing users to lose the feeling of effectiveness and engagement that stems from a more involved, complex interaction. So, if you want users to experience a sense of discovery or achievement, consider intentionally building in some interesting sources of challenge for them to overcome along the path.”
