NL Design System — The Netherlands' Cross-Government Co-Design Relay for Accessible Public Services

The NL Design System (NLDS) is a Dutch government initiative, commissioned by the Ministry of the Interior and Kingdom Relations (BZK) and coordinated by ICTU, that runs as a 'relay model' in which designers and developers from national agencies and multiple municipalities — including Amsterdam, Utrecht, The Hague and Purmerend — jointly build and maintain shared, accessible UI components rather than each government body maintaining its own.

Give citizens and entrepreneurs building blocks that are 'properly tested with users from various target groups' before certifying them, explicitly including people with visual or other disabilities, rather than treating accessibility as a checklist item.

The system's early development phase (2018-2019) included interviews with more than 20 government professionals and multicriteria-analysis workshops to prioritise which components to build first, using the UK's GOV.UK Design System and the Dutch education agency DUO's system as starting references; components only reach production-ready 'Hall of Fame' status once accessibility requirements are verified in testing.

No updated, quantified adoption figures (such as the number of organisations or live sites using NLDS components) have been published since the 2019 progress report, even though the initiative is still referenced as active in government pages from 2024-2025.

An independent 2019 progress report by Gebruiker Centraal is candid about the model's key risk: without strong top-down organisational commitment, participating agencies can 'drop out at the first technical or organisational hurdle.' This is included as an honest, evidence-strength-limited case — a genuinely participatory, disability-inclusive design methodology whose long-term adoption and impact remain undocumented rather than proven.
