The purpose of this study was to understand how radical organizational change impacts the effectiveness of national-level sport organizations from the perspectives of internal and external stakeholders. A single case study methodology of U SPORTS – the national governing body of university sport in Canada – was employed. Data sources included 32 semi-structured interviews with internal (n = 16) and external stakeholders (n = 16), as well as documentation (e.g., annual reports, financial statements). Results indicated the effectiveness of organizations can be impacted by radical change but can vary in the degree of impact, depending on the organizational effectiveness approach and stakeholder perspective used. Using both internal and external stakeholders contributes to our understanding of radical organizational change, as it demonstrates the outward impact of change on not only the focal sport organization but also its external stakeholders, which are critical for organizational survival.

这项研究的目的是从内部和外部利益相关者的角度了解激进的组织变革如何影响国家级体育组织的有效性。使用了加拿大体育部国家理事机构U SPORTS的一个个案研究方法。数据来源包括对内部（n = 16）和外部利益相关者（n= 16）以及文档（例如，年度报告，财务报表）。结果表明，组织的有效性可能会受到根本性变化的影响，但影响程度可能会有所不同，具体取决于组织有效性方法和所使用的利益相关者观点。同时使用内部和外部利益相关者有助于我们对组织的根本变革，因为它表明变革不仅对重点体育组织而且对组织生存至关重要的外部利益相关者具有外在影响。
