This technical report discusses the application of Prodoscore in measuring return on investment (ROI) and productivity within organizations. It outlines the increasing demand for efficiency due to economic pressures, particularly exacerbated by the COVID-19 pandemic. The report explains how organizations can leverage big data and cloud-based technology to quantify worker efficiency by passively collecting data on productive actions. It details a structured approach for measuring ROI, which includes identifying departments, comparison groups, and control variables, as well as establishing timeframes for measurement. The report also presents a sample logic model that illustrates how changes in Prodoscore can be correlated with business outcomes, using a coefficient of determination (R²) to predict revenue changes. Additionally, it provides metrics for calculating employee ROI and highlights the potential financial impacts of implementing Prodoscore, including annual revenue changes and cost savings from reduced absenteeism and turnover.
