This paper proposes the iStar-p model aiming to provide a visual requirements modelling language with prioritization information. This model extends i*, a goal-oriented modeling language, by including essential prioritization information, such as prioritization technique, prioritization criteria, the involved stakeholders in the prioritization and their weight, as well as the requirements priority. Early evaluation of the proposal indicates that not only it is easy to be applied and useful, but it also increases the transparency of the prioritization process, by explicitly expressing the factors used to calculate priorities.
