The Concept Of the Sensitivity Analysis : A sensitivity analysis determines how different values of an independent variable affect a particular dependent variable under a given set of assumptions. In other words, sensitivity analyses study how various sources of uncertainty in a mathematical model contribute to the model's overall uncertainty. This technique is used within specific boundaries that depend on one or more input variables.
Sensitivity analysis is used in the business world and in the field of economics. It is commonly used by financial analysts and economists, and is also known as a what-if analysis.

Main or Key Characteristics :
A sensitivity analysis determines how different values of an independent variable affect a particular dependent variable under a given set of assumptions.
This model is also referred to as a what-if or simulation analysis.
Sensitivity analysis can be used to help make predictions in the share prices of publicly-traded companies or how interest rates affect bond prices.
Sensitivity analysis allows for forecasting using historical, true data.

Working Process of Sensitivity Analysis :

Sensitivity analysis is a financial model that determines how target variables are affected based on changes in other variables known as input variables. This model is also referred to as what-if or simulation analysis. It is a way to predict the outcome of a decision given a certain range of variables. By creating a given set of variables, an analyst can determine how changes in one variable affect the outcome.

Both the target and input or independent and dependent variables are fully analyzed when sensitivity analysis is conducted. The person doing the analysis looks at how the variables move as well as how the target is affected by the input variable.

Sensitivity analysis can be used to help make predictions in the share prices of public companies. Some of the variables that affect stock prices include company earnings, the number of shares outstanding, the debt-to-equity ratios (D/E), and the number of competitors in the industry. The analysis can be refined about future stock prices by making different assumptions or adding different variables. This model can also be used to determine the effect that changes in interest rates have on bond prices. In this case, the interest rates are the independent variable, while bond prices are the dependent variable. Investors can also use sensitivity analysis to determine the effects different variables have on their investment returns.

Sensitivity analysis allows for forecasting using historical, true data. By studying all the variables and the possible outcomes, important decisions can be made about businesses, the economy, and about making investments.

Example of Sensitivity Analysis for better Understanding :

Jone M is a sales manager who wants to understand the impact of customer traffic on total sales. She determines that sales are a function of price and transaction volume.
The price of a widget is $1,000, and Jone M sold 100 last year for total sales of $100,000. Jone M also determines that a 10% increase in customer traffic increases transaction volume by 5%. This allows her to build a financial model and sensitivity analysis around this equation based on what-if statements. It can tell her what happens to sales if customer traffic increases by 10%, 50%, or 100%. Based on 100 transactions today, a 10%, 50%, or 100% increase in customer traffic equates to an increase in transactions by 5%, 25%, or 50% respectively. The sensitivity analysis demonstrates that sales are highly sensitive to changes in customer traffic.

Benefits of Sensitivity Analysis :

Conducting sensitivity analysis provides a number of benefits for decision-makers.
First, it acts as an in-depth study of all the variables. Because it's more in-depth, the predictions may be far more reliable.
Secondly, It allows decision-makers to identify where they can make improvements in the future.
Finally, it allows for the ability to make sound decisions about companies, the economy, or their investments.

Limitations of Sensitivity Analysis :

There are some disadvantages to using a model such as this.
The outcomes are all based on assumptions because the variables are all based on historical data. This means it isn't exactly accurate, so there may be room for error when applying the analysis to future predictions.
