Abstract

Having been improved, evolved and standardized by the Organization for Standardization (ISO), Functional Size Measurement (FSM) methods have become widely used. However, the measurers still face difficulties in measuring the software products which include unconventional components. We faced the challenge to observe if different interpretations or assumptions of the measurers cause significant differences in the measurement results. In this study, we present the results of a multiple case study we conducted in order to observe the impact of individual assumptions for well known FSM methods.
