  • Customer stories are written on cards
  • Cards are put into 3 piles
    • Those without which the system will not function
    • Those that are less essential but provide significant business value
    • Those that would be nice to have
  • The programmer estimates how long each requirement would take to implement and then begin to sort the requirements into 3 piles (i.e. sort by risk)
    • Those that can be estimated precisely
    • Those that can be estimated reasonably well
    • Those that cannot be estimated at all
  • Requirements are not compared against each other but again which "bucket" they are in, thus it takes $n$ time to prioritize $n$ requirements

  • Each person gets a certain amount of points to "purchase ideas"
  • The requirement that has got the highest score (amount of points given by the participants) is the most important requirement
  • This method only works once in every project (as participants learn what others will value)
  • It takes $n$ time to prioritize $n$ requirements, but because a ratio scale is used, it takes more time per decision than PG
