This document discusses maximizing return on investment in people. It notes that return on investment is a backward-looking metric best used on an ongoing basis for continuous improvement. Measuring the "benefit" of people investments can include reducing time taken for operations and incremental services offered. Organizations typically invest in people through knowledge/training, salary, and infrastructure. If returns are not commensurate, the effectiveness of instruments used for investment should be evaluated, such as perceived value by employees, relevance of training, and structure of compensation plans. Effectiveness can be measured through feedback, engagement surveys, performance tracking, and process reviews.
