Abstract: “Requirements elicitation is the most important phase during requirements engineering process in which requirements are extracted from the stakeholders. One of the vital requirements elicitation activities is requirements prioritization. Requirements prioritization is the process of selecting most significant requirements out of identified requirements. Many requirements prioritization schemes are available in literature, but none of them is considered as a standard technique. The main cause is the parameters that each technique uses. The purpose of this study is to summarize the existing techniques based on the parameters/aspects used in them. Moreover this research study is providing a big picture of prioritization models which is helpful for the researchers working in this area.”
