The design process involved all stakeholders (policymakers, local employers, civil society, service providers, users) in all stages of the process. Because specific groups have specific needs, each group was involved in appropriate ways. For example, interviews were conducted with underprivileged people, and ideas were tested with them separately rather than together with other target groups in co-design workshops. A separate focus group was organised with the support of an association working with and for mothers living in precarious situations. A diversity of profiles (considering gender, age, self-sufficiency, employment status, household structure, and so on) were included, ensuring that the needs of diverse groups were translated into research topics.
