October 2, 2019 Form
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 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.
Its even more infuriating if the question says something like. See our Guidance notes, page 6, paragraph 2. When filling in your forms people want the information they need there and then. Put yourself in the form users position and think about which questions they might have a problem with.
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.
Pre-fill where at all possible. If a person has already filled in a form for your organisation they will be frustrated if they have to fill in the same information again. It is difficult for organisations to get their systems to pre-fill known information but when pre-filling is achieved, customers really feel valued.
A light shade of a colour, like blue, across the whole background of a form relieves the eye from the harshness of a stark white background. And if the answer spaces people have to fill in are white, the tinted background both cues them in to where they write, and allows them to visually sense how much they have to fill in.
