1. Translate technical language
Explain terminology where it is needed. A short, accurate explanation next to a field is more useful than a distant glossary. Simplifying the language must not hide required disclosures or risks.
2. Name the next action
Buttons should describe what they actually do. Show progress through multi-step flows and allow corrections. Error messages should explain the problem and how to resolve it rather than relying on a red border.
3. Make numbers understandable
Charts and summaries can organise complex information. Use clear units, meaningful labels and text alternatives. A chart should support decisions without concealing important information.
4. Test real tasks
Observe whether people can complete important tasks without assistance. Ask about uncertainty rather than only overall satisfaction. Record drop-offs and misunderstandings, prioritise the main barriers and test the revised flow again.
5. Align requirements early
Involve product managers, engineers and the relevant subject-matter experts early. Clarity, data minimisation and required information belong in the same design process. Better interfaces can reduce friction; conversion effects still need to be measured separately.
