This paper presents a replication study that investigates the efficacy and likely adoption of a measurement procedure for sizing Web applications from conceptual models (OOmFPWeb). The goal of the replication was to provide evidence for the generalization of the results by repeating the experiment in a different environment, using different subjects. The results of the replica carried out in Austria have confirmed the results of the original experiment, which was carried out in Spain. OOmFPWeb is efficient when compared to current industry practices. It provides reproducible functional size measurements and is perceived as easy to use and useful by its users, who also expressed their intention to use OOmFPWeb in the future. The analysis further supports the validity and reliability of Moodypsilas method evaluation model for evaluating functional size measurement methods.
