This study focuses on the role of small technology solution providers (TSPs) in supporting digital transformation and sustainability in the manufacturing sector. It explores the challenges and opportunities of developing and adopting tailor-made technology solutions for sustainable production and the role of TSPs in the design, development, and implementation of such solutions in value constellations. It also identifies key stakeholders and summarizes the attributes of a collaboration strategy, proposing a conceptual framework and model for a collaborative process. The findings emphasize the need for long-term collaborative relationships between manufacturing companies and TSPs to successfully adopt digital transformation. Furthermore, this study includes sustainability as an outcome in the proposed collaborative process for developing tailor-made technology solutions for sustainable production. Further, collaboration can help overcome digital transformation and sustainability challenges, with TSPs playing a crucial role in supporting the twin transition. The results can guide both TSPs and manufacturing companies in their efforts to achieve sustainable and competitive production operations through digital transformation.
