3. Risk Analysis Process
The risk analysis process typically involves several steps:
Step 1: Risk Identification
This involves brainstorming, consulting stakeholders, and reviewing historical data to identify risks. Tools and techniques include:
- Checklists: Common risk categories for reference.
- Interviews and Workshops: Involving key stakeholders.
- SWOT Analysis: Evaluating strengths, weaknesses, opportunities, and threats.
Step 2: Risk Assessment
Once risks are identified, they are analyzed based on:
- Likelihood (Probability): How likely is the risk to occur?
- Impact (Severity): What is the extent of damage if it occurs? A Risk Matrix is often used to categorize risks into low, medium, or high priority.
Step 3: Risk Prioritization
High-impact and high-probability risks are prioritized. Techniques such as:
- Pareto Analysis (80/20 Rule): Focus on the 20% of risks that cause 80% of problems.
- Failure Mode and Effects Analysis (FMEA): Evaluates potential failure points systematically.
Step 4: Risk Mitigation
Strategies to handle risks include:
- Avoidance: Altering plans to remove the risk.
- Reduction: Minimizing the likelihood or impact.
- Transference: Shifting responsibility to a third party (e.g., insurance or outsourcing).
- Acceptance: Acknowledging the risk and planning contingency measures.
Step 5: Monitoring and Review
Risk profiles may evolve over time, requiring regular monitoring. Continuous feedback loops and periodic reviews ensure dynamic risk management.
