The practical starting point
A short enquiry may need a way to reply and enough detail to understand the request. It may not need a birth date or a postal address. Review every field against the actual purpose instead of keeping it because an old template included it.
A workable next step
Write a one-sentence reason for collecting each value. Mark fields that are optional and explain that accurately in the interface. Check downstream dependencies before removing a field so the form still performs its authorised task. Reducing unnecessary collection is a practical design exercise, but a complete privacy assessment depends on the wider service and applicable obligations.
Keep in your notes
- Give each field a purpose.
- Explain optional fields.
- Review downstream dependencies.
