Which of the following data entry controls provides the
GREATEST assurance that the data is entered correctly?
A. Using key verification
B. Segregating the data entry function from data entry
verification
C. Maintaining a log/record detailing the time, date,
employee's initials/user id and progress of various data
preparation and verification tasks
D. Adding check digits
Answer / guest
Answer: A
Key verification or one-to-one verification will yield the
highest degree of confidence that data entered is error
free. However, this could be impractical for large amounts
of data. The segregation of the data entry function from
data entry verification is an additional data entry control
but does not address accuracy. Maintaining a log/record
detailing the time, date, employee's initials/user ID and
progress of various data preparation and verification tasks,
provides an audit trail. A check digit is added to data to
ensure that original data have not been altered. If a check
digit is wrongly keyed, this would lead to accepting
incorrect data but would only apply to those data elements
having a check digit.
