What are the main principles of source document design?

Question

What will be an ideal response?

Answer 1

Principles of source document design include the following:
• Provide enough space, both vertically and horizontally, for users to enter the data.
• Indicate data entry positions clearly using blank lines or boxes and descriptive captions.
• Use a heading zone that contains the company name or logo and the title and number of the form.
• Use a control zone that contains codes, identification information, numbers, and dates that are used for storing completed forms.
• Use an instruction zone that contains instructions for completing the form.
• Use a body zone that contains captions and areas for entering variable data. If totals are included on the form, place them in a totals zone.
• Use an authorization zone if any signatures or approvals are required.
• Provide an information flow from left to right and top to bottom, to match the way users read documents naturally.
