The framework of a good internal control system includes:
Control environment: A sound control environment is created by management through communication, attitude and example. This includes a focus on integrity, a commitment to investigating discrepancies, diligence in designing systems and assigning responsibilities.
Risk Assessment: This involves identifying the areas in which the greatest threat or risk of inaccuracies or loss exist. To be most efficient, the greatest risks should receive the greatest amount of effort and level of control. For example, dollar amount or the nature of the transaction (for instance, those that involve cash) might be an indication of the related risk.
Monitoring and Reviewing: The system of internal control should be periodically reviewed by management. By performing a periodic assessment, management assures that internal control activities have not become obsolete or lost due to turnover or other factors. They should also be enhanced to remain sufficient for the current state of risks.
Information and communication: The availability of information and a clear and evident plan for communicating responsibilities and expectations is paramount to a good internal control system.
Control activities: These are the activities that occur within an internal control system. These are fully described in the next section.
