Frequently asked questions
- A Forrester Total Economic Impact™ (TEI) study is an independent analysis that quantifies the financial impact of a technology investment. It evaluates costs, benefits, risk reduction, and business value using customer interviews and financial modeling.
- Forrester calculates ROI by comparing the total benefits achieved, such as cost savings, efficiency gains, and reduced risk, against the total investment required, based on a modeled “composite organization” built from real customer data.
- A composite organization represents aggregated insights from multiple customers. It reflects common outcomes and scenarios, allowing Forrester to model realistic financial impact across industries without revealing individual company data.
- TEI ROI figures show the potential financial return over time based on modeled assumptions. Use them as a directional benchmark to understand possible savings, productivity gains, and risk reduction for your organization.
