An overview of the co-design approach. Strengths and challenges of users’ involvement into design

Co-design is currently one of the most emergent approaches within design practices. Building on participatory\r\ndesign tradition and User-Centered approach, this approach affirmed in the literature's headlines as well as got\r\nadopted in a wide range of practices. Being described as capable to increase general processes’ effectiveness by ensuring\r\ncompatibility between users’ needs and products/services’ features scholars emphasize the advantages of replacing\r\ntraditional top-down design approaches with a co-design one. While highlighting the advantages the field literature also\r\nindicates several challenges stemming from the adoption of co-design, generally revolving around the need to root the\r\napproach into a theoretical framework. According to an analysis of some main contributions developed in the literature,\r\nthis paper aims to point out potential developments for the field, building on the analysis of the development of the\r\napproach throughout decades and analysing the challenges that practitioners and scholars are currently facing. A\r\nconstructivist approach built on cultural psychology theory is finally argued as a theoretical framework capable to\r\nprovide an advancement for the field.
