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. 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. When designing forms make sure the response mechanism is appropriate to each question.
Customise response boxes to reflect required answers and reduce completion errors. If asking for a persons date of birth, it makes sense to provide a box with the exact number of required digits and an example or guidance note to explain the format that the date should be entered in (DD/MM/YYYY). People from different cultures have different conventions for answering seemingly innocuous questions like this.
Form length does not directly correlate to complexity. 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.
