Final answer:
The proper implementation of internal control in business includes the segregation of duties, proper documentation, and regular monitoring of operations.
Step-by-step explanation:
One business rule that illustrates a proper implementation of internal control is the segregation of duties. This means that different individuals should be responsible for different aspects of a process to prevent any single person from having too much control or the ability to commit fraud without detection. For example, in a financial setting, one person may be responsible for recording transactions while another person is responsible for approving them.
Another business rule that ensures effective internal control is the requirement for proper documentation. This means that all activities and transactions should be clearly documented and recorded in order to provide evidence of the steps taken and decisions made. Proper documentation helps in identifying any irregularities or discrepancies.
A third business rule that promotes internal control is the regular monitoring of operations. This involves reviewing and assessing processes and controls on a periodic basis to ensure that they are functioning as intended and continue to be effective. Regular monitoring allows for the identification of any weaknesses or areas that require improvement.
