Elicitation is a process during Requirements Engineering (RE) which intends to identify requirements and information about a system and its domain. It relies heavily on communications and interactions between engineers and stakeholders. One significant variable inuencing the effectiveness of such communication is Trust. While this very idea has been widely covered in manyfields of research, little attention has been paid in RE to the potential influence of trust on the elicitation effort, and therefore on the overall RE success. This paper intends to fill in this gap by providing a first empirical study on the impact of trust during requirements elicitation and by proposing a first definition of trust in the engineers and trust in the stakeholders during RE.
