%X The visibility of domain-aware element is crucially important during the requirements elicitation and definition. Requirement analysts are not necessarily domain experts and domain knowledge; during analyst-customer interaction or interviews, domain elements are not easily visible and accessible to analyst. We executed a controlled experiment with post-graduate students from computer science department at Technical university of Madrid to observe the roots, and the factors that tend to be a hurdle for requirement analysts. The study task was to elicit a known problem domain from an audio file, such as messaging application using document analysis and consolidate the elicited information from the subjects: on the on hand, from draft report and the other hand from a questionnaire. We will present results, conclusions from the research and analysis of factors that influenced the visibility of elements in known problem domain. We will reproduce some graphical comparison result from previous research work in that domain. %T Do requirements analysts focus on domain model fragments during elicitation?
