The batik fashion industry in Indonesia faces challenges in adapting to the concept of sustainability, encompassing environmental, economic, and social dimensions. This issue has become increasingly critical due to consumer pressure and government regulations demanding environmentally friendly and socially responsible business practices. However, efforts to develop products in this industry often encounter a gap between sustainable innovation and efficient product management processes. Although the Stage-Gate model has been widely adopted in various industries to enhance process efficiency in product development, there remains limited research specifically integrating sustainability aspects into the Stage-Gate model within the batik fashion industry. Based on a systematic literature review (SLR), this study aims to demonstrate how a sustainable Stage-Gate model can be effectively implemented in developing batik fashion products by addressing environmental, economic, and social sustainability (Triple Bottom Line - TBL). The Triple Bottom Line (TBL) model can be categorized into three primary approaches that reflect the evolutionary stages of sustainability implementation: 1) Stage-Gate Traditional Product Development Process (SGTPDP), 2) Stage-Gate New Product Development Process (SGNPDP), and 3) Stage-Gate Sustainable Product Development Process (SGSPDP). The findings indicate that by adapting the Stage-Gate model to include sustainability elements at every stage of product development, the batik fashion industry can become more responsive to market demands and regulatory requirements while maintaining competitiveness and environmental preservation. This study contributes to the industry by showing that a sustainable Stage-Gate model not only enhances innovation processes but also supports the overall sustainability of the batik fashion industry. © 2025 Academic Conferences Limited.
