Knowing the EVP of your product or service is crucial in assessing the financial impact on the company.  The ROI Calculator breaks the EVP calculations down into categories of Business Drivers.  By individually assessing the way in which each Business Driver impacts the EVP, the strong areas and the weak areas can be recognized.  Determining exactly what impacts the EVP leads to improvements that can maximize your company’s economic efficiency and make sure that you are investing your money, not spending it.
