On the effectiveness of dynamic modeling in UML: Results from an external replication

This paper describes the results of an external replication of an experiment for assessing whether the use of dynamic modeling influences the comprehension of software requirements. The results of the original experiment conducted in Italy did not confirm that there was a significant difference in the comprehension of software requirements when dynamic modeling is used. The goal of the replication was therefore to verify these findings with a group of more experienced students at the Universidad Politeacutecnica de Valencia (UPV) in Spain. The results shows that the use of dynamic modeling does significantly improve the comprehension of software requirements, thus providing evidence that dynamic modeling facilitates the interpretation and comprehension of requirements.
