SCENARIO ANALYSIS

Back to Glossary

Definition

Evaluating results under different sets of assumptions (best, base, worst).


Summary

Scenario analysis is a strategic planning and risk assessment technique where analysts evaluate how different potential future conditions might impact outcomes. Instead of relying on a single prediction, this method examines multiple 'what-if' situations by creating three key scenarios: best-case (optimistic assumptions), base-case (most likely assumptions), and worst-case (pessimistic assumptions). This approach helps decision-makers understand the range of possible outcomes and prepare for uncertainty, making it valuable for financial planning, investment decisions, project management, and strategic business planning.

Usage Context

Understanding scenario analysis is crucial when studying risk management, financial planning, strategic decision-making, project evaluation, and investment analysis. It's particularly important when learning about dealing with uncertainty in business environments and making robust decisions under varying conditions.

Common Confusions

  • Confusing scenario analysis with sensitivity analysis - scenario analysis changes multiple variables simultaneously while sensitivity analysis typically changes one variable at a time
  • Thinking scenarios must be equally likely - the base case is usually most probable
  • Believing you need exact probabilities for each scenario to make the analysis useful
  • Assuming the three scenarios (best/base/worst) cover all possible outcomes
