Research on software engineering at Forcolab under the supervision of Professor Shurui Zhou. Our goal is to gain a comprehensive understanding of the collaboration scenarios and challenges faced by SDEs and UXDs, as well as to propose a set of good practices to address the identified pain points. Our findings have broad applicability for collaboration in software development, extending beyond the partnership between SDEs and UXDs. The suggested best practices and interventions also act as a reference for future research, assisting in the development of dedicated collaboration tools for SDEs and UXDs.
