Determine which is the preferred design for the implementation of internal controls

Designing effective internal controls is the responsibility of management in almost every company. In some cases, there are deficiencies in the internal control environment of a company. Consider how discrepancies between the design and the implementation of internal controls may occur within any given company.
Compare the designs of your choice of two internal controls. Determine which is the preferred design for the implementation of internal controls and why it is more likely to detect accounting irregularities. Provide at least two reasons why the preferred design for internal controls is more effective than the other design. Provide a rational for your choice. Use references.
