A form is usable when it builds an effective communication bridge between your clients and your data entry staff. A usable form is readable, concise, and contains appropriate pictures and graphic elements. The steps in creating a usable form are the following: (1) Create a prototype. (2) Examine the extremes. (3) Produce the forms. (4) Fine tune the forms.
