Sensitivity Analysis : Business Analysis Explained

Sensitivity Analysis is a crucial tool in the realm of Business Analysis. It is a method used to predict the outcome of a decision given a certain range of variables. By adjusting the values of these variables within a certain boundary, analysts can understand how changes in one or more input variables impact the output of a particular function or system.

This technique is widely used in various fields such as finance, economics, engineering, physics, and many more. In the context of business analysis, sensitivity analysis is often used to forecast the impact of changes in sales, costs, and other financial variables on the profitability of a project or investment.

Understanding Sensitivity Analysis

Sensitivity Analysis is a systematic way of checking the robustness of a business decision. It allows analysts to assess the risk involved in a decision by considering the potential variability of outcomes. This is achieved by adjusting the values of certain variables and observing the impact on the overall outcome.

It is a powerful tool that can help businesses make informed decisions by understanding the potential risks and rewards associated with different scenarios. It can also help identify the most critical variables that can significantly impact the outcome of a decision.

Types of Sensitivity Analysis

There are several types of sensitivity analysis, each with its own unique approach and application. The most common types include One-way, Two-way, and Scenario-based sensitivity analysis.

One-way sensitivity analysis involves changing one variable at a time while keeping all other variables constant. This allows analysts to understand the impact of each variable on the outcome independently. Two-way sensitivity analysis, on the other hand, involves changing two variables simultaneously. This can help identify any interactions between variables that might impact the outcome. Scenario-based sensitivity analysis involves changing multiple variables simultaneously based on a particular scenario. This is often used to understand the impact of a specific event or condition on the outcome.

Application of Sensitivity Analysis in Business Analysis

Sensitivity Analysis is widely used in business analysis to help make informed decisions. It can be used to assess the viability of a new project, evaluate the potential return on investment, or even to forecast the impact of changes in market conditions on business performance.

For example, a company considering a new project might use sensitivity analysis to understand the impact of changes in sales volume, production cost, and other variables on the project’s profitability. By adjusting these variables within a certain range, the company can understand the potential risks and rewards associated with the project and make an informed decision.

Conducting Sensitivity Analysis

Conducting a sensitivity analysis involves several steps. The first step is to identify the variables that will be included in the analysis. These variables should be those that are believed to have a significant impact on the outcome of the decision or project.

Once the variables have been identified, the next step is to determine the range of values that each variable can take. This range should be realistic and based on historical data or expert judgment. The outcome of the decision or project is then calculated for each combination of variable values. This process is repeated multiple times to generate a range of possible outcomes.

Interpreting the Results of Sensitivity Analysis

The results of a sensitivity analysis can provide valuable insights into the risks and opportunities associated with a decision or project. By examining the range of possible outcomes, analysts can identify the variables that have the most significant impact on the outcome. This can help in prioritizing efforts and resources towards managing these critical variables.

Furthermore, the results can also highlight the scenarios that could result in undesirable outcomes. This can help in developing strategies to mitigate these risks. Therefore, sensitivity analysis not only helps in making informed decisions but also in managing the risks associated with those decisions.

Limitations of Sensitivity Analysis

While sensitivity analysis is a powerful tool, it is not without its limitations. One of the main limitations is that it assumes that the variables are independent of each other. However, in reality, this is rarely the case. Variables often interact with each other in complex ways, and these interactions can significantly impact the outcome.

Another limitation is that sensitivity analysis only provides a range of possible outcomes. It does not provide any information about the likelihood of these outcomes. Therefore, while it can help identify potential risks and opportunities, it cannot provide a definitive answer about the future.


Sensitivity Analysis is a valuable tool in the field of Business Analysis. It provides a systematic way of assessing the impact of changes in variables on the outcome of a decision or project. By understanding the potential risks and rewards associated with different scenarios, businesses can make informed decisions and manage their risks effectively.

However, like any tool, it is not without its limitations. Therefore, it should be used in conjunction with other tools and techniques to ensure a comprehensive analysis. Despite these limitations, sensitivity analysis remains a crucial part of the decision-making process in many businesses and industries.
