The Nucleus Research ROI Blackbook is a download of the ROI benchmark data contained in the Nucleus analyst database as of the date of publication. The data has been collected directly from customers during ROI case studies, customer interviews, and competitive situations. Benchmark ranges are reviewed by the analyst team on a regular basis and continuously updated as new data becomes available. Existing data points are aged and minimized in importance over time. Our analysts use this data as a starting point for developing a business case as well as validating estimates derived from customer experiences and surveys.
