August 20, 2019 Form
Make structure clear, and provide navigation to reinforce it. Your form will be divisible into sections so think about the broad groups of questions being asked. Whatever your groups of questions are, make sure they follow the right order and give the groups clear section names.
People from different cultures have different conventions for answering seemingly innocuous questions like this. Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters.
It is similarly annoying to them when it is a long free text box, making the customer question whether they are answering correctly and sufficiently. Providing response boxes that reflect the anticipated answer length and format reassures people that they are filling them in correctly.
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.
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).
