Abstract

Business-to-Business (B-to-B) software development companies develop services to satisfy their customers' requirements. Developers should prioritize customer satisfaction because customers greatly influence agile software development. However, satisfying current customer's requirements may not fulfill actual users or future customers' requirements because customers' 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' 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 theseissues, we propose Data-Driven Persona Retrospective (DDR) to help developers plan future releases.DDR, which includes the Persona Significance Index (PerSI) to reflect developers' commitments to end users' personas, helps developers identify a gap between developers' 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.
