|Abstract:||Existing output measurement metrics for cost estimation and development productivity need to be re-examined to determine their performance in computer aided software engineering (CASE) development environments. This paper critiques and empirically evaluates four approaches to the measurement of outputs. Two of the metrics, raw function counts and function points, are based on the function point analysis methodology pioneered by Albrecht and Gaffney at IBM (ALBR83). The second two, object counts and object points, are based on a new approach -- object points analysis -- that is introduced here for the first time. The latter metrics are specialized for output measurement in object-based CASE environments that include a centralized object repository. Estimation results for nineteen large-scale CASE projects show that the new metrics have the potential to yield as accurate, yet easier to obtain estimates than function points-based measures.|
