Co-design aims to create outcomes that are inclusive, accessible, and meaningful by embedding user insight, equity, and shared ownership from the outset. In this participatory approach, people who are affected by a project, service, or experience work collaboratively with designers, decision-makers, and other stakeholders to bring their diverse perspectives, lived experience, and professional expertise to jointly identify needs, generate ideas, and develop solutions. For example, co-design offers a collaborative approach where people with disability are actively involved in designing projects, services, or experiences that affect them, ensuring accessibility is built in from the beginning rather than added later.
