oftware is the main driver of added-value in many of the systems that surround us. While its complexity is increasing, so is the diversity of systems driven by software. To meet the challenges emerging from this combination, it is necessary to mobilize increasingly large and heterogeneous multidisciplinary teams, comprising software experts, as well as experts from various domains related to the systems driven by software. Hence, the quality of communication about software between stakeholders of different domains and with different personalities is becoming a key issue for successfully engineering software-intensive systems. The goal of this study, thus, is to investigate the effect of the representation of software design models on the communication of design decisions between stakeholders with diverse personality traits. As a result, this study finds that graphical representations of software design models are better than textual representations in enhancing the communication and increasing the productivity of stakeholders with diverse personalities.
