Usability

• The effectiveness, efficiency, and satisfaction
  with which specified users achieve specified
  goals in particular environments.
• ISO 9241

User-Centered Design

• User Centered-Design (UCD) is a philosophy and
  a process. It is a philosophy that places the
  person (as opposed to the 'thing') at the center
  it is a process that focuses on cognitive factors
  (such as perception, memory, learning,
  problem-solving, etc.) as they come into play
  during peoples' interactions with things.
• - Society for Technical Communication

User Experience

• User experience encompasses all aspects of the
  end-user's interaction with the company, its
  services, and its products. The first requirement
  for an exemplary user experience is to meet the
  exact needs of the customer, without fuss or
  bother. Next comes simplicity and elegance that
  produce products that are a joy to own, a joy to
  use. True user experience goes far beyond giving
  customers what they say they want, or providing
  checklist features. In order to achieve
  high-quality user experience in a company's
  offerings there must be a seamless merging of the
  services of multiple disciplines, including
  engineering, marketing, graphical and industrial
  design, and interface design.
• - Nielsen Norman Group

• Why do we have so many unusable things when we
  know how to make them usable? I think it has to
  do with the fact that the usability advocates
  don't understand business.
