13:6 Minimize User Data Entry

Relative Importance:

Relative Importance rating of 4 out of 5

Strength of Evidence:

Strength of Evidence rating of 3 out of 5

Document Type: Guideline


Topic:

Controls and Widgets


Guideline:

Do not require users to enter the same information more than once.


Comments:

Requiring re-entry of data imposes an additional task on users, and increases the possibility of entry errors. When entries made by users on one page are required on another page, the computer should retrieve the original entries, rather than requiring re-entry of the same information. In general, require users to make as few entries as possible.

Poor Example:

This example is poor because if the person is self-employed they will possibly have to retype the same information for home and work.

Good Example:

Clicking this button will prompt the server to copy information from the 'Billing Address' column to the 'Shipping Address' column, thus eliminating the need for users to re-input the data (if it is the same).
