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.
Users will become frustrated if when you ask for an email address, for example, if the response box only allows for 20 characters. Its similarly annoying to them when its 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.
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.
