The Department of Education describes performing a risk assessment as the foundation for developing all other security documents needed for certifying and accrediting systems and applications.(Source) The plan of action and milestones is a key organizational document and is subject to reporting requirements established by the Office of Management and Budget. Organizations develop plans of action and milestones with an organization-wide perspective, prioritizing risk response actions and ensuring consistency with the goals and objectives of the organization. Plan of action and milestones updates are based on findings from control assessments and continuous monitoring activities. There can be multiple plans of action and milestones corresponding to the information system level, mission/business process level, and organizational/governance level. While plans of action and milestones are required for federal organizations, other types of organizations can help reduce risk by documenting and tracking planned remediations. (Source)
