Cognitive-driven requirements prioritization: A case study

Prioritizing software requirements includes negotiation among people involved in the process as well as an acceptance of the prioritization criteria. The analysis includes negotiation as an important issue, which becomes extremely difficult, as clients often do not know exactly what they need. To overcome this situation, aiming at improving stakeholder´s negotiation, we propose reducing the gap of misunderstanding between them by the use of cognitive science. In this paper, we introduce a case study showing that cognitive profiles may affect requirement prioritization. A controlled experiment shows that elicitation techniques should be carefully selected according to cognitive skills to improve prioritization results.
