September 10, 2019 Form
Provide examples of the sorts of answers you are looking for, and where appropriate, provide guidance notes as near as possible to the question they relate to (i.e. in the actual form).
Provide examples and guidance and notes at the point of need. Have you ever got half-way through a form and suddenly come to a question that asks you about something you do not understand or have no idea about where to find the answer?
In paper forms the specific sub-questions cannot be hidden from the user when they are not relevant to them - but in interactive forms this is relatively easy to do. Use progressive revealing as much as possible in your form design to shield your users from questions they do not need to see.
Make the form sections visually distinct by setting the section name in bigger and bolder type, and consider including a contents list on the first page or screen to help people navigate their way through the form.
Provide checklists. As users complete your form, you may well be asking them to provide supporting information or attach supplementary documents where required. Providing a checklist, often at the beginning or end of a form, helps remind users about all the things they should remember to attach, and any further steps they need to go through.
Use appropriate response mechanisms. Paper forms have the disadvantage that users can miss, or simply disregard, an instruction. For example, only tick/check one box from a list of 15 or 20 options.
