Definition

Backfired IFPUG Function Point is an estimation of the IFPUG functional size of measure, estimation based on statistical data generated from the number of code lines of existing applications. Backfired IFPUG Function Points is computed by dividing the "Number of code lines" metric by a Gearing Factor, specific to each technology and which can be tuned.
