Verifying the Accuracy of Automation Tools for the Measurement of Software with COSMIC -- ISO 19761 Including an AUTOSAR-Based Example and a Case Study

Automating functional size measurement (FSM) is important for organizations needing to measure a large number of projects within a short timeframe, provided, of course, that the results automatically generated are accurate, particularly when such measurement is based on an international measurement standard. A literature review has shown that very little work has been conducted on verifying measurement results produced by FSM automation. This paper presents a verification protocol designed to provide evidence of the accuracy of an automated FSM tool using the COSMIC ISO 19761 measurement standard. Also included are: an example of its use for the verification of an AUTOSAR-based FSM automation prototype tool developed at ESTACA, and a case study on the application of the proposed verification protocol on another prototype tool developed at Renault S.A.
