Background: Requirements prioritization and its technique is still an important research topic. However, industry adoption of its techniques is still lack of research and has many challenges. As well, this topic involves the technology transfer.

Objectives: The objective of this study is to find what challenges for practitioner to adopt requirement prioritization techniques in practice.

Methods: We use a literature review and twice interview-based surveys. The literature review studies requirement prioritization techniques in literature. The 1st interview studies the status of practitioner’s used techniques and 2nd interview studies the practitioner’s idea towards recommended techniques in literature as well as adoption challenges. The data of interview is mainly analyzed by thematic analysis.

Results: The literature review presents the procedure of 49 requirement prioritization techniques in literatures. The 1st time interview presents the technique procedures and other conditions of 11 practitioners. With above 2 results, we find the technique recommended to these 11 interviewees and then conduct the 2nd time interview to discover more interviewees’ ideas and the challenges of technique adoption, which are also compared with related works.

Conclusions: Overall, there are many challenges for practitioner to adopt the requirement prioritization technique. As an independent subject, the practitioner’s adoption of prioritization technique still needs to be studied further: 1. Studying this subject needs to involve the scope of technology transfer; 2. Some challenges in requirement prioritization can also hamper the practitioner’s technique adoption and should be alleviated separately.
