The article has a "feel good" touch about it:) Its nice... But what is different? Water-fall: Requirements->Design->Code->Test->Ship Spiral model: R1->D1->C1->T1->S1 Get Feedback R2->D2->C2->T2->S2 Get Feedback ... and so on... So whats so different in Extreme?

  There is something called "Spiral Delta Model"
  This is waterfall folded in the middle and spiralled (Iterated).
  
  RS: Requirements Spec
  FS: Functional Spec
  D: Design
  C: Coding
  UT(P): Unit Test (Plan)
  IT(P): Integration Test (Plan)
  ST(P): System Test (Plan)
  AT (P): Acceptance Test (Plan)
  
  Waterfall:
  RS->FS->D->C->UT->IT->ST->AT
  
  Convert that to a Delta shape with iterations
  
  (RS,ATP)->(FS,STP)->(D,STP)->(C,UTP)->UT->IT->ST->AT
  
  This is a tight Delta Spiral. And after a few
  cycles, we hopefully hit the bulls eye!:)
  
  As we know, different models are appropriate for
  different stuations. So what are the salient differences of Extreme Prog and when is is appropriate?
  
  The article makes good reading but leave hugh and dry
