Since 2015, the School of engineering and architecture at the University of Zaragoza (EINA), and the automotive and mobility cluster of Aragón (CAAR), a non-profit association, both in the city of Zaragoza, the capital of Aragon region in the north of Spain, have collaborated on various initiatives aimed at enhancing the qualifications of School students to facilitate their integration into the association industrial companies. One such initiative is the development of a learning factory, intended to bridge the educational and business communities in the region of Aragón. The objective of this project is to validate a learning factory design tailored to the engineering community by addressing stakeholder requirements and assessing the feasibility of a long-term sustainability model. Several design methodologies, including those proposed by Metternich, Tish, Enke, Ranz, Abele, Vera, Raunch, and Matt, were evaluated. The analysis encompassed diverse design strategies, from stakeholder-centered approaches to the application of methodologies such as axiomatic design, morphological analysis, and benchmarking. Additionally, the integration of existing educational laboratories into the production process was assessed to minimize the initial investment required to implement a learning factory. The study concludes with the validation of a collaborative public-private model that optimizes both public resources and private contributions, while simultaneously improving the soft skills training of engineering students.
