In some situations, information is recorded in a log or entered into a database more than one time, creating no added value. This is also called data redundancy. Changing the process to require only one entry can lead to improvement in productivity and quality (by reducing discrepancies). Recent technology developments (such as optical scanners) make it possible to enter data directly from sight or by voice. Once data is recorded, there should be no reason to reenter the same information at a later time.
