Abstract Product development is a critical part of all business operations. In fashion apparel, product development is a complicated process. In recent years, with the advance of technologies and the growing public awareness of environmental protection, product development processes (PDPs) in supply chains, including fashion supply chains, need to be environmentally sustainable. In this paper, we first identify the commonly seen supply chain structures in the fashion industry. Then, by examining the product development process in practice and in the literature, we identify the essential steps in fashion PDPs, which include planning, product design, manufacturing, and product launching. We further classify the product development process into three types, namely the traditional product development process (TPDP), new product development process (NPDP), and sustainable product development process (SPDP). Furthermore, we analyze the key factors of achieving sustainable fashion based on the triple bottom line (TBL) framework regarding the PDP. We establish a sustainable product development process (SPDP) matrix, which can guide the fashion supply chain members to operate in a sustainable manner during the SPDP. Finally, we reveal open research issues and propose a future research agenda.

时尚界的可持续产品开发流程：供应链结构和分类

摘要 产品开发是所有业务运营的关键部分。在时尚服饰中，产品开发是一个复杂的过程。近年来，随着技术的进步和公众环保意识的增强，包括时尚供应链在内的供应链中的产品开发过程（PDP）需要具有环境可持续性。在本文中，我们首先确定了时尚行业中常见的供应链结构。然后，通过检查实践和文献中的产品开发过程，我们确定了时尚 PDP 的基本步骤，包括规划、产品设计、制造和产品发布。我们将产品开发过程进一步分为三类，即传统产品开发过程（TPDP）、新产品开发流程（NPDP）和可持续产品开发流程（SPDP）。此外，我们基于有关 PDP 的三重底线 (TBL) 框架分析了实现可持续时尚的关键因素。我们建立了可持续产品开发流程（SPDP）矩阵，可以在SPDP期间指导时尚供应链成员以可持续的方式运作。最后，我们揭示了开放的研究问题并提出了未来的研究议程。
