In business as in life, the only thing that’s certain is uncertainty. Scenario analysis is a powerful process for navigating the uncertainty of the future by analyzing the potential business impacts of future events and considering alternative possible outcomes. Companies can use scenario analysis to explore a broad range of possible future situations, from economic slowdowns and natural disasters to expanding a product line or opening new offices.

What Is Scenario Analysis?

Scenario analysis is a technique that provides a rational and structured way to analyze the future. Businesses can use it to examine different potential impacts of negative and positive events, such as:

  • What are the possible impacts on the business of an economic slowdown?
  • What happens to revenue and profitability if the cost of various raw materials rises?
  • What revenues might be generated by a new product line?
  • How would the business be impacted by the unexpected market entry of new competitors?

Scenario analysis doesn’t attempt to predict a single outcome from any of these events. Instead, it examines a spectrum of different potential situations and outcomes, typically ranging from a best-case to worst-case scenario. Businesses can then conduct scenario planning to better prepare for these events and their potential impacts.

Scenario analysis is not new. It was pioneered by the US military during the mid-1900s, and Shell Oil started using it during the 1970s to analyze and respond to fluctuations in global oil supplies. It’s now widely used by businesses, thanks in part to financial modeling tools that eliminate much of the manual effort and make the process much faster. It may be even more important for small businesses than for larger ones, since smaller companies may be more heavily impacted by a single event. Scenario analysis is employed by financial services companies to analyze risks and make investment decisions, and it can even be used to analyze household finances.

Key Takeaways

  • Scenario analysis helps businesses plan for the future by analyzing the business impact of potential events and strategic decisions.
  • Scenario analysis is valuable for businesses of any size and can be used to analyze a wide variety of situations, from the impact of economic slowdowns and disasters, to new product launches.
  • Modern software tools allow finance teams to leverage financial intelligence and built-in features to rapidly model multiple scenarios to deal with change and give them confidence in decision making.

Scenario Analysis Explained

Scenario analysis is a practical method for navigating uncertainty and enhancing decision-making across an organization. It supports corporate governance by giving company leaders the ability to evaluate different courses of action for a range of potential future conditions. This helps them think long-term and choose the best path forward by laying out the financial impacts of both possible risks and opportunities.

From a risk management perspective, scenario analysis plays a key role in identifying vulnerabilities in current strategies and operations. It also supports preparedness, providing leaders with the information needed to proactively create targeted contingency plans should the scenarios occur. Further, scenario analysis demonstrates a commitment to comprehensive, forward-looking strategy and risk awareness—priorities for many company boards and investors. For the financial planning team, scenario analysis enriches forecasting and budgeting processes by considering multiple potential outcomes. This yields more thoughtful and flexible financial plans.

Beyond these practical applications, scenario analysis fosters organizational agility. It encourages teams to explore various possibilities, challenges assumptions, and promotes more objective thinking. This improves decision quality and helps build a culture that more readily identifies opportunities for innovation.

Why Businesses Need Scenario Analysis

Changes that impact the business environment can happen unexpectedly and suddenly—as demonstrated in magnified ways by the global pandemic in 2020. Scenario analysis allows organizations to analyze and quantify potential business impacts of such events, so they can plan accordingly. It can also be used to assess the benefit and risks of different business decisions, such as the potential impact on revenue and profitability of building new facilities. It helps businesses avoid diving blindly into a risky investment or project.

How Scenario Analysis Works

A scenario analysis considers a potential event and the business scenarios that may result—the potential future states or, as they’re sometimes called, alternative worlds. Generally, a range of scenarios are considered, from best to worst. For each scenario, the company makes assumptions about its effect on different factors that are important to the business, such as interest rates or the cost of raw materials. These assumptions are then used as input variables to model the impact of each scenario on the business.

Scenario analysis may consider many different factors. Analysis of the potential financial impact of constructing a new facility might consider labor, rent, utilities, taxes, and other costs, for example.

Let’s take the imaginary example of Kooky Cooks Inc., a maker of innovative kitchen equipment. The company comes up with an idea for a new appliance that not only cooks food but also cleans itself afterwards. However, it will take at least a year to get the product to market and financial analysts are predicting worsening economic conditions over that period.

The company could use scenario analysis to examine the potential impacts of economic conditions on the revenues and profits generated by the new product. Economic conditions may affect a variety of factors, from customer demand to the cost of raw materials. The company could consider a range of scenarios, each generating a different set of assumptions.

In one scenario, sales might fall by 20% because customer demand declines due to the economic conditions, while the cost of raw materials rises because some suppliers go out of business and there’s less competition among the remaining providers. However, rent on manufacturing facilities could fall by 10% and the company might be able to borrow money at a lower interest rate to fund manufacturing start-up costs. Scenario analysis could consider the impact of all these factors.

Types of Scenarios

One key benefit of effective scenario analysis is that it drives decision-makers to consider a range of potential situations, each with its own set of assumptions. This can help prevent businesses from becoming fixated on a single, overoptimistic view of the future and developing business plans that assume ideal conditions and outcomes. In addition to the common best- and worst-case framework, there are several distinct types of scenarios that organizations can explore, each serving a different purpose:

  • Normative scenarios are built around the most likely or expected outcomes, grounded in current trends and known variables. These help businesses align their plans with what seems most probable so they can allocate their resources appropriately. Normative scenarios can be thought of as a broader, more exploratory kind of forecast.
  • Extreme or edge case scenarios examine unlikely but potentially high-impact events. Also known as “black swan” scenarios, these are not expected to occur, but exploring them helps organizations test their resilience and better prepare for the unexpected.

Scenario analysis can also be categorized by whether the focus is on internal or external factors:

  • Internal scenarios concentrate on elements within the company’s control, such as operational improvements, staffing changes, or product development initiatives.
  • External scenarios address outside factors, such as shifts in consumer behavior, regulatory changes, competitive actions, or macroeconomic conditions.

Scenarios can differ based on time horizon:

  • Short-term scenarios tend to look ahead one or two years. They are useful for tactical decisions and immediate risk management.
  • Long-term scenarios often span five to 10 years or more. They are geared toward big-picture changes, such as new technologies or demographic shifts.

It’s a good idea to incorporate a mix of these scenario types to improve the quality of strategic thinking, since the goal of scenario analysis isn’t to predict the future with certainty but to prepare for a range of possibilities For example, a common application of scenario planning—a new product launch—would likely combine short-term scenarios for the initial launch, with long-term scenarios for market adoption, scalability, and profitability.

Cases in Scenario Analysis

A scenario analysis generally considers at least three types of scenarios:

  • Base-case scenario: A baseline scenario based on current, commonly accepted assumptions.
  • Worst-case scenario: The most negative set of assumptions.
  • Best-case scenario: The ideal projected scenario to achieve goals and objectives.

For example, in Kooky Cooks’ best-case scenario, revenues might actually rise because people stay at home and do more cooking instead of eating out. In the worst-case scenario, demand falls while all costs rise. In the base case, current trends continue into the future. Each of these scenarios has a different impact on revenue and profit.

Examining a range of scenarios provides the company with a range of possible outcomes for planning purposes. For example, the best-case scenario might result in a net profit margin of 20%, while the worst-case scenario results in a margin of 5%. The company uses the range of 5%-20% to guide its decisions about investing in the manufacture of new products.

A company may also assign probabilities to each scenario, based on its assessment of the likelihood that it will occur. This can help to guide the company’s subsequent planning and decisions about how to allocate resources.

Multiple scenario analysis: Scenario analysis doesn’t have to be restricted to just three possible cases. A company may consider many different scenarios, each using a different set of assumptions. The trade-off is that more scenarios require more effort to analyze them.

Components of Scenario Analysis

Effective scenario analysis relies on four clearly defined components—key drivers, scenario case, time horizon, and scenario scope—that work together to clarify assumptions, set boundaries, and tailor analysis to specific business needs. Without them, the process is at risk of becoming vague, impractical thought exercises. The components also facilitate consistent comparisons across scenarios, making it easier to identify patterns and stress-test decisions.

  • Key drivers are the internal and external variables that most significantly influence outcomes. Examples include factors like production capacity and marketing spend or market demand and interest rates. The key drivers form the foundation of the scenario analysis, so it is vital to properly identify them. They are the inputs that get adjusted in different scenarios.

  • A scenario case provides the specific assumptions and conditions used for each analysis. Each case should be internally consistent, meaning the assumptions align with each other and are plausible. They should also be directly relevant to the decision at hand, excluding elements that are not core to the issue. Finally, the scenario case should be plausible.

    Here is an example of a scenario case that contains all three of these characteristics: In response to new government incentives for renewable energy, a solar panel manufacturer sees a 25% increase in residential demand, triggering a decision to expand production capacity while navigating increased competition and supply chain pressures.

  • Time horizon defines how far into the future the scenario extends. The selected horizon should match the strategic context. For instance, a pharmaceutical company might use a 10-year outlook for research and development, while a retailer might use a one-year horizon for inventory planning.
  • Scenario scope sets the boundaries of what the analysis will cover, including the range of factors and the level of detail in the analysis. It should be broad enough to capture meaningful variables but focused enough to remain manageable. For example, a fast-food chain’s scenario scope would include factors like dietary trends and food prices by product category but might scope out office supply costs.

Benefits of Scenario Analysis

Key benefits of scenario analysis include:

  • It helps companies manage risks more proactively by assessing the impact of potential future events and situations.
  • It can help businesses make better decisions by investigating the risks and benefits of different options.
  • The methodical approach to analyzing the future may enable companies to spot opportunities or risks that might otherwise be overlooked.
  • It can make communication with stakeholders more productive by using well-defined future scenarios. It also increases the likelihood of gaining support for strategic decisions.
  • It improves resource allocation by helping organizations prioritize investments and efforts based on potential future impacts.

Challenges of Scenario Analysis

  • Scenario analysis can be a time-consuming process that requires specific skills and expertise, although modeling tools can help.
  • It can be difficult to envision all possible scenarios, make realistic assumptions, and assign probabilities to them.
  • It can be hard to translate the insights gained from scenario analysis into concrete strategic decisions and actions.

Scenario Analysis vs. Sensitivity Analysis

Scenario analysis is sometimes confused with sensitivity analysis. But there’s a key difference. Scenario analysis makes assumptions about multiple variables and factors for possible future scenarios and looks at how each would affect the business. Sensitivity analysis, in contrast, examines the effect of changing a single input variable while keeping all the other variables constant. For example, a company might examine how a change in the lending interest rate could affect the company’s profitability or cash flow.

6 Steps to Perform a Scenario Analysis

Taking a methodical approach to scenario analysis can help a company stay focused on the most important scenarios, consider the most relevant factors, and get the most benefit from the process. Here are six key steps:

  1. Define the issue: This includes mapping out the decisions you need to make.
  2. Gather data and identify key factors, trends and uncertainties that may affect the plan: This may include external factors such as market shifts, political changes, competitive threats, and trends in customer behavior. It may also include internal factors such as the company’s key strengths and development capabilities.
  3. Develop a scenario planning template: This is generally a financial model (see below) that enables the company to plug in various assumptions and examine the impact on key metrics such as revenue or net income.
  4. Develop scenarios: Develop base-, worst-, and best-case scenarios, plus others if desired. To get the broadest view of potential scenarios and assumptions it’s important to involve people with relevant knowledge across the organization. This can also help avoid unconscious bias and potential blind spots.
  5. Evaluate the scenarios: Analyze the potential impact of each scenario.
  6. Plan accordingly: Use the scenarios you have developed in your planning, weighing the most likely risks and rewards.

Example Scenario Analysis

The following example shows how a hypothetical small business might follow these six steps to perform a scenario analysis when deciding whether to launch a new product. Consider a small local bakery, “Nicole’s Kitchen,” that is contemplating the addition of a new gluten-free product line.

Step 1: Define the issue and decisions

Nicole’s Kitchen is interested in introducing a line of gluten-free products. The main decisions are whether to launch this new line and how much to invest in it.

Step 2: Gather data and identify key factors

Nicole’s Kitchen puts on its research cap and investigates:

  • Local demand for gluten-free products
  • Market prices for gluten-free products in the area
  • Cost of gluten-free ingredients
  • Required equipment investments
  • Potential impact on existing product sales
  • Competitors’ gluten-free offerings

Step 3: Develop a scenario planning template

Nicole’s Kitchen creates a simple spreadsheet to calculate:

  • Projected weekly sales volume of gluten-free products
  • Proposed sales prices for each new product
  • Projected revenue of gluten-free products
  • Costs (ingredients, equipment, additional staff training)
  • Overall impact on bakery profits

Step 4: Develop scenarios

Nicole’s Kitchen creates three scenarios:

  • Base case: 50 gluten-free items sold per day at $4 each. Gluten-free products account for 15% of sales within 6 months.
  • Best case: 80 gluten-free items sold per day at $4.50 each. Gluten-free products account for 25% of sales within 6 months.
  • Worst case: 20 gluten-free items sold per day at $3.50 each. Gluten-free products account for only 5% of sales within 6 months.

Step 5: Evaluate the scenarios

Nicole’s Kitchen assesses the scenarios:

  • Base case: Profit increase of 10% after 1 year
  • Best case: Profit increase of 20% after 1 year
  • Worst case: Profit decrease of 5% after 1 year due to unsold inventory and equipment costs

Step 6: Plan accordingly

Based on the analysis, Nicole’s Kitchen decides to:

  • Launch a small line of gluten-free products.
  • Start with minimal equipment investment.
  • Monitor sales closely for the first 3 months.
  • Plan to expand the line if sales meet or exceed the base case.
  • Prepare a marketing plan to promote the new gluten-free options.

What Is Scenario Modeling?

Scenario analysis generally captures a range of possible outcomes that will help cultivate agility, support business continuity, and promote growth. In times of uncertainty, scenario modeling helps businesses build models that allow them to assess the impact of their business plans on revenue, expenses, and cash flow.

Originally, the calculations were performed manually. Now, companies can use a variety of tools, from spreadsheets to sophisticated modeling software that is integrated with financial and operational source systems.

Scenario Analysis and Financial Modeling

Scenario analysis imagines a range of scenarios, each with its own assumptions. Once the company describes each scenario and the associated assumptions, it can perform the analysis by entering those assumptions into a financial model. The model turns the assumptions into quantifiable impacts, such as a 10% increase in revenue. The value of the analysis depends on the accuracy of the model and the data on which it is built. Realistic assumptions and an in-depth knowledge of the company’s business are key to creating an accurate model.

Using Financial Modeling Tools for Scenario Analysis

Scenario analysis has traditionally been an extremely labor-intensive process, involving manually gathering data from disparate sources inside and outside the company and entering the data into spreadsheet-based financial models. Even the simple example of Nicole’s Kitchen demonstrates how this approach isn’t scalable for developing multiple scenarios or in more complex use cases.

NetSuite ERP has a built-in scenario planning and modeling module that makes scenario analysis much faster and easier for companies of all sizes. It can generate scenarios based on any number of variables and at differing levels of detail, such as product, location, or customer. Drawing upon the unified database, it pulls in the appropriate financial and operational data, increasing data integrity by eliminating the need to transfer data manually. It automatically performs complex calculations and makes it easy to run as many different versions as needed by swapping out assumptions. NetSuite makes it feasible to conduct scenario analysis on a regular basis and apply it to more situations, including smaller day-to-day operational decisions and issues.

Scenario analysis is a vital tool for decision-making, offering a structured, actionable framework for navigating uncertainty and change. By modeling a range of possible future conditions, both positive and negative, companies can better anticipate risks and seize opportunities. Whether assessing a new product launch, responding to market shifts, or engaging in contingency planning, scenario analysis boosts agility and helps organizations become more proactive. The most effective scenario planning follows a set process that incorporates all key components and is supported by modeling software.

Scenario Analysis FAQs

What is the difference between scenario analysis and forecasting?

Forecasting is the development of a single outcome that is most likely to occur based on historical data and current trends. Scenario analysis explores multiple outcomes, including the best, worst, and likely cases. Forecasting tends to focus on an upcoming time period, such as the next quarter or fiscal year, while scenario analysis takes a short-term or long-term perspective.

Is scenario analysis qualitative or quantitative?

Effective scenario analysis incorporates both qualitative and quantitative factors. Expert judgment and narratives about market trends, technology changes, and consumer behavior all play an important role in developing meaningful scenarios. Quantitative aspects include calculating the financial outcome of each scenario and assigning probabilities, often drawing upon statistical models.

What is the purpose of scenario testing?

Scenario testing is a risk management technique that focuses on the potential impacts of an envisioned scenario on a company’s financial results, operations, or processes. It is commonly used for contingency planning to help a business be prepared for potential outcomes. Stress testing is a form of scenario testing that is also a compliance requirement in some financial service sectors.
