Guidance on form question design

[anikbrazeau]

Context

Based on explorations in #4808

Potential opportunities

To enable the design of better forms for end users filling them out we might consider creating guidance or pointing to existing guidance / best practice around:

• Only asking what is necessary (question protocol)
• Asking one thing per page (see GDS standard)
• Writing good questions (deep dive into specific patterns if you must ask for X)
• Optimizing labels and hint text (what is most clear and useful)
• Labelling required fields (how to decide)
• Improving data validation
• Customizing error messages
