Companies can measure the impact of their programs aimed at fulfilling employees' psychological needs by conducting regular surveys, analyzing employee feedback, tracking key performance indicators, and monitoring employee retention rates. To ensure continued success and sustainability in the long term, companies can implement strategies such as providing ongoing training and development opportunities, fostering a positive work culture, offering competitive benefits and compensation packages, promoting work-life balance, and actively seeking and incorporating employee input and suggestions into program improvements.
