What-If Scenario Analysis
What-if scenario analysis is a data analysis technique that evaluates how different scenarios or conditions would affect project outcomes, enabling proactive planning for various possibilities.
Explanation
What-if scenario analysis involves evaluating the effects of different conditions or events on the project schedule, cost, or other objectives. The technique asks "what if X happens?" and models the impact to help project managers prepare for various possibilities. It is commonly used in schedule development, risk response planning, and resource optimization.
In schedule management, what-if scenario analysis might examine the impact of delayed resource availability, scope changes, or external dependency failures on the project timeline. The results help identify activities that are most sensitive to change and where schedule buffers or contingency plans may be needed.
This technique is closely related to simulation (such as Monte Carlo analysis) but can also be performed through simpler manual calculations or spreadsheet models. It supports risk management by helping the team understand the range of possible outcomes and develop appropriate response strategies.
Key Points
- •Evaluates the impact of different scenarios on project outcomes
- •Commonly used in schedule development and risk management
- •Helps identify schedule-sensitive activities and needed buffers
- •Can range from simple manual calculations to complex simulations
Exam Tip
What-if analysis asks about specific scenarios and their impacts, while Monte Carlo simulation runs many scenarios probabilistically. Both are used in schedule risk analysis.
