In our presentation, we will talk about the transformational journey that Santander Bank Polska went through from the first design experiments carried out by a group of enthusiasts to the cross-cutting standardisation of the product development process. We will show how to effectively implement service design on the scale of such a large organisation and why a dedicated framework plays an important role. We also explain how to effectively communicate the value of design in a business-focused environment and why you don't need many designers at all to make Service Design work well in your organisation.
