The Challenger is a project of open innovation applied to learning where teams of students from different programmes at Barcelona School of Management in Spain work on the same business challenge. The project aims to move towards a new integral model of learning, based on resolving real life business challenges that really connect students with the world of work. Each year the challenge changes. Last year it involved working with fashion company Mango to find innovative publicity tools that allow them to reach different consumer sectors all around the world but with a sustainability focus. The winning team presented the idea of developing a series of new bags designed by young designers around the world with money going to good causes.
