This approach helps to capture both the complexity of multiple variable changes and the depth of each variable’s impact. It supports a more informed, comprehensive view of potential risks and opportunities, reinforcing the decision-making process. You might find that a 1% increase in interest rates leads to a 5% decrease in the portfolio value, making the portfolio highly sensitive to interest rate changes. This insight could be critical for future investment decisions, as it helps identify where potential risks and opportunities lie. All business decisions are based on a set of assumptions that always come with a certain level of risk.
- One key difference between both approaches is that sensitivity analysis is a process of testing individual drivers in a budget or forecast to find the levers that have the most effect on a business.
- You might find that a 1% increase in interest rates leads to a 5% decrease in the portfolio value, making the portfolio highly sensitive to interest rate changes.
- The events that occurred in 2020 and 2021 due to the global COVID-19 pandemic lend themselves as a great example, although this particular event would be quite difficult to predict.
Your model is changing much more frequently than it used to, which means you may have to make sensitivity analysis a regular activity alongside scenario planning. Sensitivity analysis gives you in-depth insight into which drivers you should build scenarios around. This makes your scenario analysis exercises more targeted, saving you from rebuilding models for different scenarios that won’t necessarily help you with business decision-making.
What Is Scenario Analysis?
Hence, it would make sense to account for overall future scenarios and then use expected values for each variable. On the other hand, scenario analysis might be more appropriate if you are trying to analyze how many units of a product must be sold before the business will break even. It is not enough to look at each variable in isolation as each of them will be related to another.
Sensitivity analysis is the method where we determine how much each variable affects the output by changing it incrementally and examining the results. The best-case scenario – This could assume strong market growth leading to higher than average sales, along with successful cost optimization efforts reducing operational costs. The base-case scenario – You might base this on conservative estimates of market trends and projected sales, alongside the current operational cost structure. Sensitivity analysis is a powerful tool used to understand how changes in one specific variable can impact a given outcome. By solely varying the economic conditions from thriving to recessionary, while keeping other factors constant, the owner measures how sensitive the revenue is to economic fluctuations. You’d build the baseline model and then create two duplicates — one that increases headcount and holds attainment steady and one that increases attainment assumptions while holding headcount steady.
On the other hand, scenario analysis entails making several premises about different independent variables and then examining how the outcome changes. In the example above, the inventor would examine how other factors (other than price) would affect the sales of his revolutionary mobile case composite material. On the other hand, scenario analysis assesses the effect of changing all the input variables at the same time.
The primary difference between sensitivity analysis and scenario analysis is the desired outcome. With scenario analysis, you’re not a damn thing to predict a single outcome from any event. Rather, you’re looking at a spectrum of potential situations and outcomes generally ranging from a best-case to worst-case scenario. Those who do have the time and resources, especially businesses which have many potential factors that can influence output, would benefit greatly by conducting sensitivity analysis.
We and our partners process data to provide:
If the cost of raw materials doesn’t rise too much, they may not actually see a dramatic change in the number of units sold. However, if the cost of raw materials dramatically increases, they may see a dramatic decrease in the number of units sold simply because they have to adjust the pricing to profit margins in line. In one situation, sales may fall by 30% because customer demand declines as a result of economic conditions.
How to use scenario analysis for supply chain disruption

Regardless, preparing for more such events in the form of a second or third wave will allow some of these companies to continue operations, such as pivoting to e-commerce stores or food deliveries for retail businesses. As you can imagine, fluctuations in the stock market impact many aspects of the performance of a what advantage does scenario analysis have over sensitivity analysis business. As a result, considering hypothetical situations regarding the market is an important task for companies that want to grow. For example, if you wanted to know the effect of a future event on your investment, you would have to input the expected values for that parameter in such an event. Below is the sensitivity analysis table model template provided by WSO to test out an example of these types of changes.
The analysis can help stakeholders identify and work to avoid high-risk situations or implement a business strategy that may increase revenue. Sensitivity analysis can be better understood by exploring financial models that show how you can change a variable to see how it affects another variable in an investment portfolio under different scenarios. With the increasing complexity of models and their variables, we need to be able to make inferences about what is going on based on limited data. For example, you might want to know the probability of an event happening given a certain parameter or variable or the effects of changing a parameter. For this example, let’s assume you’re the head of a finance team, and your company is considering a significant investment like opening a new factory.
