Early FP Estimation and the Analytic Hierarchy Process
Luca Santillo · 2000
Several methods exist in order to estimate the size of a software project, in a phase when detailed Function Point counts cannot be performed. While the Derived Estimation (or Algorithmic Model) Methods result in more accurate, objective, and repeatable estimates, these need always to be calibrated through a set of historical (statistical) data; this also means that estimation for atypical cases or new software typologies cannot be provided because of this "calibration from the past".
