Inaccurate data entry. As an example, consider a typical relational database management system, where
update queries are used to change records, tables and reports. If the contents of the query are incorrect,
errors might be produced within all of the data manipulated by the query. Although extreme, significant
problems might be caused by adding or removing even a single character to a query.
- Attempts to carry out tasks beyond the ability of the employee. In smaller computer-based information
systems, a common cause of accidental damage involves users attempting to install new hardware items or
software applications. In the case of software applications, existing data may be lost when the program is
installed or the program may fail to operate as expected.
- Failure to comply with procedures for the use of organisational information systems. Where organisational
procedures are unclear or fail to anticipate potential problems, users may often ignore established methods,
act on their own initiative or perform tasks incorrectly.
- Failure to carry out backup procedures or verify data backups. In addition to carrying out regular backups
of important business data, it is also necessary to verify that any backup copies made are accurate and free
from errors.
