The technologies of the experimental units 2 and 3 were selected considering that the industrial partner was already familiar and skilled with them. It is clear that there exist many other equivalently powerful alternatives for units 2 and 3. However, opting for an alternative would have required a training effort that could not be afforded by the partner because of budget constraints. In any case, apart from budget constraints and assuming the possibility to opt for an alternative, we can argue that, whatever (reasonably) long the training could last, it would be not easy to reach the same level of expertise, hence possibly compromising the validity of the experiment.

The experiment was conducted by two different development teams. The team involved in the experimental unit 1 was formed by two developers of the **CHOReVOLUTION** project. The other team, involved in the experimental units 2 and 3, was formed by the above two developers plus two other developers from a different project. The experimental tasks were distributed to the different developers. This helped to eliminate the potential bias of person-task links. All developers had equivalent professional skills and familiarity with the concerned technologies.

All developers had equivalent professional skills and familiarity with the concerned technologies. All of them started performing their tasks out of already specified choreographies for the SMT use cases. Thus, the choreography specification phase was not part of the experiment.

**-Hypothesis 1-** We found that the **CHOReVOLUTION** approach significantly decreased the time required to implement the STM use case.
