The UK Government has published an alpha release of its digital design principles with examples of how they have been used so far.
1. Start with needs
2. Do less
3. Design with data
4. Do the hard work to make it simple
5. Iterate. Then iterate again.
6. Build for inclusion
7. Understand context
8. Build digital services, not websites
9. Be consistent, not uniform
10. Make things open: it makes things better
