For the Dialogue Session format, we present "Failures on Display," an exploration and reflection on the main mistakes made in the planning, design, and realization process of an exhibition. Over the past ten years, the Institute of Design (IDe) within the Department Environment, Construction, and Design (DACD) at SUPSI has curated, designed, and executed numerous scientific exhibition spaces and museum displays. Throughout these years, we have gathered a wealth of experience, not only celebrating successes but embracing the errors made by students and professionals as opportunities for learning, growth, and improvement. The strategy we have developed incorporates the use of cards to analyze and reflect on these errors. Each card represents a specific mistake or challenge on wich we can discuss and learn from. Mistakes in material and technology selection, communication and interaction errors, as well as logistical, planning, and scheduling errors, are just some of the many obstacles encountered during the realization of many projects. The problematic aspects related to exhibition realization will be addressed through this format, striking the right balance between pragmatic considerations and scientific rigor. "Failures on Display" reminds us that the process of designing and creating an exhibition is a journey filled with challenges and opportunities for growth, but also with pitfalls. However, every mistake made can be an opportunity to learn and improve our skills. Through an open and honest perspective, we embrace mistakes as an integral, useful, and even creative part of our design process.
