Internal Control Limitation
Limitations in the internal control system consist of lack of training or communication, collusion, lack of management support, human error, staff size, or cost benefit considerations. Lack of training or communications can consist of employees not being trained in internal controls or not understanding correct procedures (McIntosh). Collusion is where employees find ways to work around the internal control system. It can include two or more employees exchanging passwords and entering false transactions. Lack of management support constitutes the tone at the top. Without management support, employees are not properly supervised.
Human error comes from carelessness, distraction, misunderstanding, or mistakes in judgment (Rennels).

Sound policies and practices acts as an internal control that when enforced and monitored by management helps employees to be fair and honest in ways that the use of company assets are efficiently used. The policies and practices enable management to encourage ethical behavior at all levels of the organization. This also requires that employees are strongly trained and understand the policies and the consequences for not following them. Training should also be an ongoing issue so employees are trained and made aware as changes in policy and legal requirements come up.
Segregation of duties structures work assignments so one employee's work serves as a check on other employees. For example, authorization being required for certain items allows management to check on an employees work to ensure that policies are followed. If an employee has custody of cash and records transactions, transactions can be manipulated and cash stolen by the same…
