Test Driven Modeling: The Impact on Maintenance (Replication)

This experiment is a replication of our previous experiment investigating the impact of test cases on model maintenance (details can be found here). As no significant differences with respect to quality could be found in the previous experiment, we increased the complexity of the models to be adapted. In addition, we slightly simplified the instructions to avoid misunderstandings. The experiment was carried out using Cheetah Experimental Platform. All material used for this experiment can be found in the download links in the following section.


The experiment makes use of repeated measurement, hence 50% of the subjects received these assignments, the other 50% the other assignments. The assignments include a download link that directly lead to further instructions and used material.

To support subjects during the experiment and to avoid that constraints were misunderstood, subjects received this handout.
