September 11, 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).
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.
Also make sure that you make good use of features like running headers and footers on every page to remind people what the form is, where they are, and what page number they are on.
Many assume that making forms shorter makes them easier to complete. Though shorter forms might be cheaper to produce initially, if the reduction in content results in user confusion, the cost of resolving completion errors form fillers make as a consequence can significantly outweigh any initial savings. In general forms do need to be as short as possible, but never at the expense of clarity and usability.
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.
In this context interactive forms can be programmed so that the user can only tick/check one (known as a radio button as distinct from check-boxes), or presented with the options in a drop-down menu from which the user can only select one.
