This document outlines an 11-step process for quantifying the return on investment (ROI) of library technology projects. The process involves: 1) conducting an environmental scan of potential projects; 2) outlining program assumptions and objectives; 3) identifying impact points of current and new processes; 4) establishing a conversion standard; 5) collecting data on impact points; 6) estimating changes and project savings; 7) identifying project costs; 8) considering qualitative benefits; 9) calculating ROI; 10) writing a report; and 11) following up after implementation. The goal is to reduce risk, allocate resources effectively, and validate technology investment claims using both quantitative and qualitative metrics.
