Are Featutres the right things on which to focus?

A series of four Blog posts over the past few days have put forth the idea that projects should focus on outcome more so than features.

• Franks Sommer's Blog entry
  Valuing Outcomes Over Features on November 3 summarizes the other blog discussions.
  In that discussion he mentions the others.
• Dan North's entry Outcomes over Features - the fifth agile value
• Ditch the feature shopping list. Think customer journeys
  introduces the concept of customer journeys
• Martin Fowler's Feature Devotion

This concept is also apparently contained in the book What Customers Want. Definitely an area I will want to investigate further.
