Form is used to collect or present information into or outside from the system. Form can be used to get input or to present output, but normally, it has been used to collect input from users. System input has been identified during the system requirement process. A form is a business document contains predefined data and may include certain parts that need to be filled in by user. The form should be designed to meet the purposed of the form. Designing a form, is known as user-focused activity since the development of forms should be based on user's requirements and needs. And that's why the use of prototyping approach is the most appropriate. Figure 10-1 shows the form and input design that should be conducted during this phase.
