"Service Design" is a field that leverages methodologies from the field of design for the benefit of process and systemic projects in the public or business sector and in characterizing the interface points with them. If in the past, a product of a design project was essentially physical, then in the service design the products include action plans, formulation and characterization of processes, access to information, design characterization of communication language and interface points - in physical space, digital and related materials. The development of the field came as a result of the growing recognition of the contribution of design to the construction of significant processes in complex spaces and systems, out of an in-depth understanding of the set of variables, needs and partners in the project. Today, large-scale projects in health systems, municipal services, banking, academia, and the business sector are led by designers, in favor of building quality services that generate value for users. The course is conducted in the form of a concentrated seminar, during which students become acquainted with the research methods and work steps used in the field and perform a complete process at the end of which a programmatic proposal, system components, characterization of the design language are presented. This year the course dealt with the subject of nutrition and physical activity among children and adolescents in routine and times of crisis (Corona limitations, social distance, lockdown, and quarantine).
