Risk Analysis

When to Use This Skill

Use this skill when:

• Risk Analysis tasks - Working on risk analysis using risk registers, probability/impact matrices, and mitigation planning. identifies, assesses, and manages project, business, and technical risks with structured response strategies
• Planning or design - Need guidance on Risk Analysis approaches
• Best practices - Want to follow established patterns and standards

Overview

Systematically identify, assess, and manage risks using risk registers, probability/impact matrices, and structured response planning. Supports project risks, business risks, technical risks, and opportunity management.

What is Risk Analysis?

Risk is an uncertain event or condition that, if it occurs, has a positive or negative effect on objectives. Risk analysis involves:

• Identification: What could happen?
• Assessment: How likely? How impactful?
• Response Planning: What will we do about it?
• Monitoring: Track and update risks

Risk vs Issue

Threats vs Opportunities

Risk Register

The central repository for all identified risks:

## Risk Register

| ID | Risk Description | Category | Probability | Impact | Score | Owner | Response | Status |
|----|-----------------|----------|-------------|--------|-------|-------|----------|--------|
| R-001 | [Description] | [Category] | H/M/L | H/M/L | [P×I] | [Name] | [Strategy] | Open |

Response Planning Template

## Risk Response Plan: R-001

**Risk:** [Description]
**Strategy:** [Avoid/Transfer/Mitigate/Accept]

### Prevention Actions
| Action | Owner | Due Date | Status |
|--------|-------|----------|--------|
| [Preventive measure] | [Name] | [Date] | [Status] |

### Contingency Plan
**Trigger:** [What indicates risk is occurring]
**Actions:**
1. [Contingency action 1]
2. [Contingency action 2]

### Residual Risk
**After mitigation:**
- Probability: [Reduced level]
- Impact: [Reduced level]
- New Score: [Residual score]

Workflow

Phase 1: Risk Identification

Step 1: Gather Inputs

Sources for risk identification:

• Project plans and schedules
• Stakeholder concerns
• Historical data from similar projects
• SWOT analysis (Threats)
• Technical assessments
• External environment analysis

Step 2: Brainstorm Risks

Techniques:

• Checklist review: Standard risk categories
• Expert interviews: Subject matter experts
• Assumption analysis: Test project assumptions
• Root cause analysis: Work backward from impacts
• SWOT: Threats and opportunities

Step 3: Document Risks

Risk statement format:

"There is a risk that [CONDITION/CAUSE] may result in [CONSEQUENCE/IMPACT]"

Example:
"There is a risk that key developer leaves may result in schedule delay and knowledge loss"

Phase 2: Risk Assessment

Step 1: Assess Probability

For each risk:

• What is the likelihood of occurrence?
• What evidence supports this assessment?
• Use defined scale (1-5)

Step 2: Assess Impact

For each risk:

• What would be the consequence?
• Consider multiple impact types (schedule, cost, quality)
• Use the highest impact dimension
• Use defined scale (1-5)

Step 3: Calculate and Prioritize

## Risk Assessment Summary

| ID | Risk | P | I | Score | Priority |
|----|------|---|---|-------|----------|
| R-001 | [Risk 1] | 4 | 5 | 20 | Critical |
| R-002 | [Risk 2] | 3 | 3 | 9 | Medium |
| R-003 | [Risk 3] | 2 | 2 | 4 | Low |

Phase 3: Response Planning

Step 1: Select Response Strategy

For each significant risk:

• Match strategy to risk characteristics
• Consider cost of response vs. risk exposure
• Assign risk owner

Step 2: Define Response Actions

• Specific, measurable actions
• Clear owners and due dates
• Contingency triggers defined

Step 3: Calculate Residual Risk

After planned mitigations:

• Re-assess probability and impact
• Calculate residual risk score
• Determine if acceptable

Phase 4: Monitoring

Step 1: Track Risk Status

Regular review cadence:

• Critical risks: Weekly
• High risks: Bi-weekly
• Medium risks: Monthly
• Low risks: Quarterly

Step 2: Update Register

• New risks identified
• Risk scores changed
• Responses executed
• Risks closed or occurred
