What is Total Economic Impact™?

The Forrester Consulting Total Economic Impact study helps companies demonstrate, justify, and realize the tangible value of their products and solutions to various stakeholders and prospective customers. The TEI framework provides a rigorous, structured approach to measuring and communicating the financial impact of technology investments. TEI studies also examine the potential risks and flexibility that a technology investment might offer.

There are several key components of the Total Economic Impact studies commissioned by NETSCOUT. These include:


These are the positive outcomes, both financial and non-financial, of the implementation of the solutions in the study, which are part of the Visibility Without Borders platform. This shows the increases in revenue, cost savings, and operational efficiencies of the Visibility Without Borders platform.


This shows the future value that the Visibility Without Borders platform may provide an organization. This can include the ability to capitalize on new opportunities in the future.


These include the expenses incurred during the purchase, implementation, and running of the solution, including upfront, operational, maintenance, training, and other expenses.


These are potential challenges or negative outcomes that may reduce the overall benefits a solution provides. This can include under-delivery on promised benefits, implementation difficulties, and unanticipated costs.

A TEI study aims to provide a comprehensive view of the total economic impact a technology solution provides by blending and quantifying these components. This assists organizations in making informed decisions when vetting possible solutions while also allowing vendors to showcase the value proposition of their solutions.
