Developers should prioritize customer satisfaction because customers greatly influence agile software development. However, satisfying current customer\u2019s requirements may not fulfill actual users or future customers\u2019 requirements because customers\u2019 requirements are not always derived from actual users. To reconcile these differences, developers should identify conflicts in their strategic plan. This plan should consider current commitments to end users and their intentions as well as employ a data-driven approach to adapt to rapid market changes. A persona models an end user representation in human-centered design. Although previous works have applied personas to software development and proposed data-driven software engineering frameworks with gap analysis between the effectiveness of commitments and expectations, the significance of developers\u2019 commitment and quantitative decision-making are not considered. Developers often do not achieve their business goal due to conflicts. Hence, the target of commitments should be validated. To address these issues, we propose Data-Driven Persona Retrospective (DDR) to help developers plan future releases. DDR, which includes the Persona Significance Index (PerSI) to reflect developers\u2019 commitments to end users\u2019 personas, helps developers identify a gap between developers\u2019 commitments to personas and expectations. In addition, DDR identifies release situations with conflicts based on PerSI. Specifically, we define four release cases, which include different situations and issues, and provide a method to determine the release case based on PerSI. Then we validate the release cases and their determinations through a case study involving a Japanese cloud application and discuss the effectiveness of DDR.<\/jats:p>","DOI":"10.1142\/s0218194021500029","type":"journal-article","created":{"date-parts":[[2021,2,7]],"date-time":"2021-02-07T02:29:54Z","timestamp":1612664994000},"page":"117-146","source":"Crossref","is-referenced-by-count":3,"title":["Data-Driven Persona Retrospective Based on Persona Significance Index in B-to-B Software Development"],"prefix":"10.1142","volume":"31","author":[{"given":"Yasuhiro","family":"Watanabe","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Waseda University, 3-4-1 Okubo, Shinjuku-ku, Tokyo, 1698555 Japan"}]},{"given":"Hironori","family":"Washizaki","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Waseda University, 3-4-1 Okubo, Shinjuku-ku, Tokyo, 1698555 Japan"}]},{"given":"Yoshiaki","family":"Fukazawa","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Waseda University, 3-4-1 Okubo, Shinjuku-ku, Tokyo, 1698555 Japan"}]},{"given":"Kiyoshi","family":"Honda","sequence":"additional","affiliation":[{"name":"Osaka Institute of Technology, 1-79-1 Kitayama, Hirakata City, Osaka, 5730196 Japan"}]},{"given":"Masahiro","family":"Taga","sequence":"additional","affiliation":[{"name":"e-Seikatsu Co., Ltd., 5-2-32 Minamiazabu, Minato-ku, Tokyo, 1060047 Japan"}]},{"given":"Akira","family":"Matsuzaki","sequence":"additional","affiliation":[{"name":"e-Seikatsu Co., Ltd., 5-2-32 Minamiazabu, Minato-ku, Tokyo, 1060047 Japan"}]},{"given":"Takayoshi","family":"Suzuki","sequence":"additional","affiliation":[{"name":"e-Seikatsu Co., Ltd., 5-2-32 Minamiazabu, Minato-ku, Tokyo, 1060047 Japan"}]}],"member":"219","published-online":{"date-parts":[[2021,2,4]]},"reference":[{"key":"S0218194021500029BIB001","doi-asserted-by":"crossref","first-page":"89","DOI":"10.1145\/3183399.3183410","volume-title":"Proc. 40th Int.
