Function points are proven to be effective and efficient units of measure for both agile/iterative and waterfall software deliveries. However, inconsistencies come to light when comparing function points counted in agile/iterative development with those counted in waterfall or combination development . These inconsistencies can create confusion for cost, productivity, and schedule evaluations that span multiple software delivery methods. This paper, recently published on IFPUG's Beyond MetricViews by QSM Consultant Carol Dekkers, seeks to marry International Function Point Users Group (IFPUG) definitions with equivalent concepts in agile/iterative processes in order to create a basis for consistent comparison.
