XYZ Ltd. is a company that provides financial services to clients. The company has a policy of providing performance-based incentives to its employees, based on the amount of revenue they generate. However, the company's HR department has not updated the incentive structure for several years, and the incentives are now much lower than the industry standards. As a result, many of the top-performing employees are leaving the company to join competitors who offer higher incentives.
