Answer: the control principle of separation of duties is violated

Explanation: because

It is a security principle that allows for separation of duties with the primary objective of preventing fraud and error by having more than one person to complete a task

separation of duties is violated.

Explanation:

In accounting and auditing, separation of duties is essential because it doesn't allow one single employee to be able to complete a task involving funds or assets by himself/herself. At least two people are required to complete the task in order for each one to be able to control the other employee's work.

For example, one single employee cannot be responsible for determining what assets need to be purchased, at what price they will be purchased, which vendor will provide them and finally be responsible for paying the invoices.

When one individual has the authority to decide one thing, another employee must be able to control if that decision was logical and correct. E. g. one department requests materials, another department must determine which vendor will provide the materials and the cost, and finally, the finance department must pay for the materials and receive the invoice. This will happen only after the original department that made the request confirms that the materials were received.
