Background: Though the academic has been studying the requirement prioritization methodology, the industry still encounters challenges of the requirement prioritization in real world. Most academic models only study requirement prioritization under some limited contexts. Unexpected factors induce the challenges when practicing a requirement prioritization method. Objectives: The objective of this study is to find what challenges to practice requirement prioritization methodologies commonly need to be improved or have been neglected. Methods: We used systematic mapping study and interview-based survey. The systematic mapping study conducts the overview and generalization on the present requirement prioritization techniques in the academic. The survey does the interview on the actual status of practicing requirement prioritization in real world. The data of both methods is qualitatively analyzed by thematic analysis. Results: Through the systematic mapping study on 17 articles, we found some characters common in the design of the academic requirement prioritization models, about the usual workflow step, advantage and limitation. Then through the survey with 14 interviewees, we studied what method the practitioner is most using and what challenge exists to practice the requirement prioritization in real world, mainly related to the workflow and limitation of these practical methods. Finally, based on the contrast of results above, we find what challenge for practitioners between the academic and practical methods worth to be improved or studied further. Besides, according to the acquired empirical insights, we proposed some potential future trends. Conclusions: This study elicited the challenges and insights to practice requirement prioritization methods, which brings the value to inspire the industry for designing and applying more productive requirement prioritization method. Besides, based on the empirical result, we proposed 2 new definition (Practicable Requirement Prioritization Engineering and Modularized Requirement Prioritization Model) and 1 potential situation (Requirement Prioritization of Compounded-Business Software) worth to be studied for the future trend.
