To establish a Circular Supply Chain (CSC), companies must instigate transformative changes at the supply chain level, engaging various stakeholders both within and beyond their organizational boundaries through collaborative and open innovation efforts. However, existing literature lacks both successful examples of companies implementing circular economy principles and practical guidance on the strategies firms should employ to effectively coordinate resources and capabilities for Sustainability-Oriented Innovation (SOI) within CSC. To address these gaps, this study conducts a longitudinal field study with embedded cases, focusing on the sustainable fashion company, that for confidentiality reasons will be referred to as Alpha, as the main unit of analysis. The investigation delves into the Resource Orchestration (RO) mechanisms employed to successfully develop various SOI initiatives (sub-units of analysis). The study provides valuable insights into strategies and practices conducive to achieving triple bottom line outcomes and introduces a RO Perspective framework for SOI within a CSC. Ultimately, the findings underscore the significance of tailoring Resource Orchestration mechanisms to different SOI initiatives. This research contributes to the accumulation of knowledge at the intersection of Circular Economy, SOI, and RO Perspective and offers practical implications for companies seeking to orchestrate their networks to achieve a CSC.
