quality, security and confidentiality of client documents and
data are key items in the DEB's mission statement. The following
procedures are in place to ensure full compliance. |
The
DEB considers quality and data accuracy as a major objective.
We aim to provide our clients the highest level of accuracy.
We do this by maintaining stringent checks on client data at
all times during the keying process. These checks form part
of a company-wide standard operating procedure, which is always
followed. In the area of quality control, in addition to key
and verify, we have specific edits and validation tables that
are customized by our experienced programmers for each job.
These validation routines are algorithms that examine and compare
results against predetermined standards. We have three basic
types of validation routines:
' |
| Table
look-ups |
 |
|
In
a table look up one or more fields are validated against a database.
If there is an exact match the statistical odds are good that
the data is correct.
'
|
| Data/range
checks |
|
|
With
data/range checks the field or character information is compared
with a model to see that it conforms to a specific type, such
as a specific alphanumeric sequence or date, such as an invoice
date. A validation routine might also check to see that a number
is within a specific range or contains a certain number of digits.

validation is when a column of numbers totals correctly. If
there is a match on the total, then the probability is extremely
high that all the numbers are correct. All data fields are systematically
analysed to ensure data validity and integrity. |

the variables that the quality control system check are: |
