Once you have your goals, you need to choose the appropriate metrics to track and evaluate them. Metrics are quantitative or qualitative indicators that measure the progress and outcomes of your retention program. For instance, turnover rate, which is the percentage of employees who leave the organization within a given period, and retention rate, which is the percentage of employees who stay with the organization within a given period, are two common metrics for retention. Additionally, you should consider metrics such as tenure (the average length of service of your employees), engagement (the degree of commitment, involvement, and enthusiasm of your employees), satisfaction (the level of happiness and fulfillment of your employees), performance (the quality and quantity of work output of your employees), and loyalty (the degree of attachment and identification of your employees with the organization). You should select the metrics that are most relevant and meaningful for your goals and industry, as well as define how you will collect, analyze, and report the data for each metric.
