Abstract
We carried out a controlled experiment and an external replication
to investigate whether the use of requirement diagrams of the
SysML (System Modeling Language) helps in the comprehensibility of
requirements. The original experiment was conducted at the University
of Basilicata in Italy with Bachelor students, while its replication was
executed at the University of Gothenburg in Sweden with Bachelor and
Master students. A total of 87 participants took part in the two experiments.
The achieved results indicated that the comprehension of requirements
is statistically higher when requirements speci cation documents
include requirement diagrams without any impact on the time to accomplish
comprehension tasks
