The IR plan (Incident Response Plan) is used in the event of an incident or emergency to respond to and manage the situation. It outlines the procedures and responsibilities for responding to incidents such as natural disasters, cyber attacks, fires, or other emergencies. The IR plan is used to ensure a coordinated and effective response to minimize the impact of an incident and ensure the safety of individuals and the protection of assets. The IR plan is essential for organizations, especially in industries such as engineering and critical infrastructure, to prepare for and respond to unexpected events.
