Risk Analysis – What You Need to Know

Once potential risks have been identified, they’re analyzed in two main ways: qualitative and quantitative. These terms can sound intimidating, but the difference is fairly straightforward.

Qualitative Analysis
Qualitative risk analysis is more subjective and focuses on prioritizing risks based on their likelihood and impact.

  • Estimate how likely each risk is to occur (e.g., Low, Medium, High, or a 1–10 scale)
  • Assess the potential impact if the risk does occur (again, Low, Medium, High, or 1–10)
  • Plot the results on a probability–impact matrix
  • Use this to highlight which risks need deeper analysis

Quantitative Analysis
Quantitative analysis takes a more data-driven approach and uses numbers to evaluate risk more precisely.

  • Relies on measurable, verifiable data to assign numerical values
  • Applies mathematical methods to estimate probability and impact
  • May use tools like simulations (e.g., Monte Carlo), decision trees, expert input, interviews, and cost/time estimates
  • Forecasts likely project outcomes in terms of cost and schedule
  • Produces a prioritized list of risks based on their overall effect
