Definition of risk management
Risk management is the process of identifying, quantifying, and managing the risks that an organisation faces. As the outcomes of business activities are uncertain, they are said to have some element of risk. These risks include strategic failures, operational failures, financial failures, market disruptions, environmental disasters, and regulatory violations.
While it is impossible that companies remove all risk from the organisation, it is important that they properly understand and manage the risks that they are willing to accept in the context of the overall corporate strategy. The management of the company is primarily responsible for risk management, but the board of directors, internal auditor, external auditor, and general counsel also play critical roles.
As factories can be dangerous places to work, it is important that companies implement appropriate risk management processes. For example, a company can reduce the likelihood of an accident by limiting work schedules (to reduce employee fatigue), locating equipment in areas that are less vulnerable to damage, performing regular maintenance on equipment, performing regular environmental reviews and establishing communication protocols between line workers, supervisors and management.
