5 ways to make sure that users abandon your forms:
- Ask for information the user doesn't have at their finger tips
- Ask for a lot of information, but don't tell why you need it
- Force users to input data according to how the system wants it
- Provide cryptic error messages that tell users to correct their mistakes, but give no information about what they did wrong
- Split forms up into many segments, but don't give any indication of where users are in the process

I you follow these rules, be sure to overstaff your call center. You're going to need the extra help.
