Employing Data Tables

Using data tables to create scenario analysis models in Excel is an easy and efficient way to summarize and visualize data. Data tables can help analyze large datasets, quickly highlight potential outcomes, and allow users to compare multiple scenarios.

Definition & Process

A data table is a grid that examines the sensitivity of the calculated results to a number of influencing variables. When evaluating multiple assumptions, the user can input these assumptions into the data table, which will then recalculate different outcomes based on those assumptions. Excel’s data table feature is used to create a data table based on a given set of assumptions and to analyze its outcomes.

Output Snapshots

The output snapshot from a data table is a summary of results, typically displayed as a table or graph. This snapshot can be instantly adjusted with a simple drag and drop for quick and easy comparison. The output graph or table will help visualize the outcome so that users can identify key trends and draw conclusions from the data.


Data tables are very useful when building scenario analysis models in Excel. By comparing multiple scenarios, users can get a better understanding of how assumptions can impact the outcome. Additionally, data tables can calculate multiple scenarios much faster than manual input and provide a simple snapshot of the results. In short, data tables are a great way to quickly analyze and compare a range of assumptions.

Utilizing Matrices

Matrix calculations are an effective way of modeling uncertainty while analyzing multiple scenarios. Through intuitive inputs and straightforward calculations, matrices enable users to identify the best possible outcome. The process of building a scenario analysis model with matrices can be broken down into three core steps: definition, process, and output snapshots.

Definition & Process

When creating a matrix for a scenario analysis model, first define the elements that will be inputs and outputs. The key elements are the variables, outcomes, and potential decisions. The goal is to determine the best decision based on the given variables. With the elements understood, you can begin creating the mathematical formulas to assign values to each cell of the matrix. These formulas can range from simple arithmetic operations to more complex mathematical equations. For two-dimensional matrices, the process is repeated for each row and column to eventually complete the matrix.

Output Snapshots

The results of a matrix can be displayed in a number of ways. A graphical representation of the matrix may be useful to quickly identify where the maximum and minimum values are located. Other output formats include a pivot grid, tabular report, and pivot chart. Depending on your needs, any combination of these output formats can be utilized.


Using matrices to model scenarios is an effective and efficient way to produce results in a timely manner. The ability to arrange data into a two-dimensional matrix simplifies data organization and makes it easy to compare multiple scenarios. Matrices are also versatile and can be used in a variety of industries, from finance and marketing to engineering and production. By analyzing the data in matrices, business decisions can be made quickly and accurately.

Implementing Decision Trees

A decision tree is an efficient, graphical representation of the options and possible outcomes of a decision-making process. It is an approach to analyzing complex decision-making scenarios in which decisions are taken one after another and the outcomes of each one affect the next one. Decision trees are easily constructed from a flow chart of the process and can be implemented in Excel.

Definition & Process

In Excel, decision trees are created using worksheet formulas. Data related to the decision choices is entered into the worksheet and formulas are used to analyze the data. Charting functions can then display the information in a tree format that illustrates the possible outcomes. There are various sub-factors involved in the decision tree, such as possible decisions or alternative branches, probability of outcomes and expected value of outcomes.

Output Snapshots

Excel decision trees offer various features to visualize the outcomes of a decision. Snapshots may be taken of different stages of the decision tree, along with any strategic decisions taken at that stage. These snapshots can give a detailed overview of the process, allowing for alternative scenarios to be explored.


  • Decision trees help identify scenarios in which decisions are most sensitive to changes in cost or risk.
  • Decision trees easily display the options and potential outcomes in a concise manner.
  • Excel provides an easy-to-use graphical interface for decision tree analysis.
  • Decision trees help identify the most cost-effective course of action.
  • The snapshots feature helps to audit decision-making during the process.
