This paper proposes a framework and tool for conducting laboratory experiments
with collaborative systems. The framework and tool seek to control a large
number of experimental conditions, while obtaining fine-grained log data about
the individual and collaborative activities. Furthermore, the proposed
framework and tool allow reusing voice communication and questionnaire modules.
The paper also reports a laboratory experiment where the framework and tool
were used to analyze the impact of collaboration support on teams performing
maintenance activities on a network infrastructure. The obtained results
highlight the capacity of the framework and tool to facilitate collaborative
systems evaluation.
