A preventive system developed to increase the readiness of enterprises in crisis and emergency situations to avoid business discontinuity and to continue providing essential services to customers, suppliers, regulators, and other entities that need access to these services under any circumstances. These include day-to-day activities such as project management, backup, change control, and support services. Business continuity is not a plan that is implemented at the time of a disaster; it refers to those daily activities that ensure that services are maintained continuously.
