I lead the team behind the NDW Design System. Every week we update it so all systems stay current, and we add new components that are used in all our applications.
Together this keeps NDW's applications consistent and reliable.
All components of the NDW Design System, documented in one place.
The components in a realistic context, with a WCAG page the Design System team set up so Cardan, which performs the official testing, can check that the components meet the WCAG guidelines.
The interface is only one layer of the experience.
Great digital products don't become complex because of one bad screen. They become complex when the layers around the experience stop connecting. I work between those layers.
Strong digital products depend on the relationship between six layers.
Understand users, context, systems and the actual problem.
Connect users, stakeholders, product, design and technology.
Turn complex information and flows into clear experiences.
Create solutions, systems and patterns that work beyond one screen or one team.
