Risk analysis is a systematic process for identifying and evaluating potential events or conditions that could affect an organization's objectives. It aims to understand the nature of risk, estimate likelihood and consequence, and provide a basis for decision making and risk treatment.

The typical workflow includes risk identification, assessment of likelihood and impact, prioritization, selection of response options, and ongoing monitoring. Analyses can be qualitative, using categories such as low, medium, and high, or quantitative, employing numerical estimates, probabilistic models, and simulations. The choice depends on data availability, stakes, and context.

Common techniques include risk matrices, fault tree analysis, event tree analysis, Monte Carlo simulation, sensitivity analysis, and scenario planning. The outputs often include a risk register, heat maps, residual risk assessments, and alignment with risk appetite and tolerance. The results inform risk treatment plans and monitoring strategies.

Risk analysis is central to standards and frameworks such as ISO 31000, ISO 31010, and NIST SP 800-30, and is used within corporate governance and enterprise risk management frameworks like COSO ERM. It applies across sectors, including finance, information security, healthcare, engineering, and project management.

Key challenges include data quality and availability, uncertainty, interdependencies among risks, dynamic environments, and cognitive biases. When conducted rigorously, risk analysis supports better decision making, efficient resource allocation, improved resilience, and regulatory compliance.
