Perform Quantitative Risk Analysis

Introduction

• Quantitative Risk Analysis numerically evaluates the potential impact of risks on project objectives, such as cost, time, and scope.
• Builds upon qualitative analysis, where risks are ranked by priority.
• Focuses on high-priority risks, providing precise numerical values to guide response planning.

---

Purpose

• To determine the monetary or temporal effect of individual risks on the project.
• To update the Risk Register with quantitative data, aiding in informed decision-making.

Key Concepts

Qualitative vs. Quantitative Analysis

• Qualitative Analysis:
  • High-level assessment of risk probability and impact (e.g., "high probability, high impact").
• Quantitative Analysis:
  • Numerical evaluation of risks, assigning specific costs, delays, or other measurable impacts.

When to Use Quantitative Analysis

• For high-priority risks identified in the qualitative phase.
• When detailed, precise data is available, often requiring industry expertise or specialized tools.

Tools and Techniques

1. Representation of Uncertainty:

   • Probability Distribution:
     • Assesses the likelihood of risk events.
     • Example: The more frequently you perform an activity, the greater the chance of related risks.
   • Triangular and Beta Distributions:
     • Compare best-case, worst-case, and most likely scenarios to analyze uncertainty.

2. Sensitivity Analysis:

   • Identifies how much different risks affect project objectives.
   • Tornado Chart:
     • Visualizes the influence of risks on various aspects of the project.
     • Example: Rising HR costs may impact development significantly more than other risks.

3. Decision Tree Analysis:

   • Evaluates decisions under uncertainty by calculating Expected Monetary Value (EMV):
     • Formula: $$EMV = \text{Risk Impact} \times \text{Probability}$$
     • Example:
       • Risk Impact: $400,000.
       • Probability: 25% → EMV = $100,000.
     • Helps determine the best course of action considering potential risk costs.

4. Simulation (e.g., Monte Carlo Analysis):

   • Uses random sampling to predict project outcomes under various risk scenarios.
   • Useful for projects with complex interdependencies.

Outputs

1. Risk Register Updates:

   • Quantitative details added to the risks identified earlier:
     • Cost impact.
     • Time delays.
     • Probability of occurrence.
   • Example:

     Risk ID	Description	Probability	Impact	EMV
     R1	Material Delay	30%	$50K	$15K
     R2	Regulatory Change	20%	$80K	$16K

2. Project Document Updates:

   • Include updated risk assessments in the Risk Report and related project plans.

Critical Considerations

1. Complexity:
   • Quantitative analysis often requires specialized tools, expertise, and data.
2. Focus on High-Priority Risks:
   • Not all risks need quantitative analysis; prioritize those with significant potential impact.
3. Accuracy of Data:
   • Ensure data quality for reliable results; poor data can skew the analysis.

---

Common Challenges

1. Lack of Expertise:
   • Industry-specific knowledge is often required for accurate assessments.
2. Data Availability:
   • Limited historical data can make numerical evaluations less reliable.
3. Cost vs. Benefit:
   • Quantitative analysis can be resource-intensive, so focus efforts where the benefit outweighs the cost.

Conclusion

• Perform Quantitative Risk Analysis provides precise insights into how risks affect the project, enabling better response planning.
• By assigning numerical values to risks, project managers can prioritize resources effectively and develop informed strategies.
• This process is vital for complex projects but requires expertise, accurate data, and a focus on high-priority risks for maximum value.
