Individuals and organizations use various types of controls to make sure a process or system does not stray too far from standards, requirements, or accepted practices. While useful for protection of the organization, these controls can increase costs, reduce productivity, and stifle improvement. Typical forms of controls include a layered management structure, approval signatures, standardized forms, and reports. A regular review of all of the organization's control procedures by everyone working in the system can result in identifying opportunities to reduce controls on the system without putting the organization at risk.
