Designing Internal Controls

Before designing an internal control plan, you should understand the basic types of internal controls and how they are intended to function. When deciding on the types of controls to implement, consider the unit's objectives and business goals and the associated risks and materiality. All controls require the appropriate training, communication, and oversight by unit management to ensure they are being implemented appropriately and operating consistently.

Frequency of Controls

Depending on the underlying processes or functions, associated risks, and desired control objectives, control activities may be designed to operate at varying frequencies: recurring, daily, weekly, monthly, quarterly, annually, or as-needed (ad hoc). You may need more frequent controls for higher risk processes or functions.

Primary Types of Control Activities

Depending on when they are intended to function, there are two basic types of internal control activities: preventative and detective. An optimal system of internal controls will have both.

Preventative Controls

Preventative controls protect the university by helping to identify and address problems before they happen.

Detective Controls

Detective controls are designed to find errors or fraud in transactions after they have occurred, as well as identify missing assets or invalid transactions. Properly designed and operating detective controls will also help determine if preventative controls are functioning properly.

An important detective control is reconciliation, which compares two sets of data to one another, and identifies/investigates differences.

Other detective control examples include:

When controls find errors or improper activities, unit management must take sufficient remedial actions, including root-cause analysis and error correction, and implement necessary corrective measures to prevent such issues from recurring.

Other Types of Controls

You should also consider including these important characteristics of internal controls when designing controls to implement in unit-level internal control plans:

Manual vs. Automated Controls

Depending on the control objective, available data and resources (e.g., software), and other factors, controls may be manual or automated.
