What Is a Risk Assessment?
A risk assessment is a structured method for identifying what could go wrong, estimating the likelihood and impact of each risk, and deciding which risks require mitigation. Organizations use risk assessments to make informed decisions about resource allocation, insurance, compliance, and strategic planning. Risk assessments are required by many regulatory frameworks including ISO 27001, NIST, SOC 2, and OSHA.
The Risk Assessment Process
Risk assessment follows five steps: (1) Identify risks by brainstorming, reviewing historical incidents, and analyzing processes. (2) Analyze each risk by estimating its likelihood (probability of occurring) and impact (severity of consequences). (3) Evaluate risks by plotting them on a risk matrix to determine priority. (4) Treat risks through mitigation, transfer (insurance), acceptance, or avoidance. (5) Monitor and review risks on an ongoing basis as conditions change.
Risk Assessment Matrix
A risk matrix plots likelihood on one axis and impact on the other, creating a grid that categorizes risks as Low, Medium, High, or Critical. A risk with high likelihood and high impact is Critical and requires immediate mitigation. A risk with low likelihood and low impact can be accepted and monitored. Most organizations use a 5x5 matrix with scores from 1 to 25, where the risk score equals likelihood multiplied by impact.
Types of Risk Assessments
Qualitative risk assessments use descriptive scales (Low/Medium/High) and are faster to complete. Quantitative risk assessments assign dollar values to potential losses and calculate expected monetary value. IT risk assessments focus on cybersecurity threats, data breaches, and system failures. Compliance risk assessments evaluate regulatory exposure. Project risk assessments identify threats to scope, schedule, and budget. Most organizations start with qualitative assessments and add quantitative analysis for high-priority risks.

Frequently Asked Questions
How often should risk assessments be performed?
Risk assessments should be performed at least annually for organizational risks, at the start of every project for project risks, and immediately after significant changes such as new systems, regulatory updates, or security incidents. High-risk industries like healthcare and finance may require quarterly reviews. Continuous monitoring supplements periodic formal assessments.
What is the difference between risk assessment and risk management?
Risk assessment is one step within the broader risk management process. Risk assessment identifies and evaluates risks. Risk management includes assessment plus the ongoing activities of mitigating, monitoring, and communicating about risks. Think of assessment as the diagnosis and management as the full treatment plan including follow-up care.
Who is responsible for risk assessment in an organization?
Risk assessment responsibility varies by type. IT security risk assessments are owned by the CISO or IT security team. Financial risk assessments are owned by the CFO or finance team. Project risk assessments are owned by the project manager. Enterprise risk management is typically overseen by a Chief Risk Officer or the executive leadership team. All employees should participate in identifying risks in their areas.
