The principle mainly includes the following aspects:

Employee status reset: Amazon's performance clearing means that the performance status of all employees will be reset, whether they are good or poor performers. This means that every employee will start from scratch and start a new round of performance appraisal.

Appraisal standard changes: Amazon adjusts performance appraisal standards every year based on employee feedback and changes in market demand. Before each performance clearing, the company will evaluate the existing performance standards to determine whether adjustments are needed. If there are adjustments, employees will face new challenges in the new year.

Bonus issuance: At Amazon, performance appraisal is directly related to rewards. By achieving or exceeding performance targets, employees have the opportunity to receive additional rewards or promotion opportunities. Therefore, before the start of a new performance appraisal cycle, the company will settle the performance appraisal results of the previous year and issue corresponding bonuses to employees.

Work goal adjustment: After the performance clearing, employees may face new work goals or tasks, which may include redefining job roles or adjusting job responsibilities. These changes are designed to ensure that employees can better adapt to the company's current and future business needs.

To sum up, the principle of Amazon's service provider performance clearance involves resetting employee status, changing assessment standards, issuing bonuses, and adjusting work goals. These measures together constitute part of Amazon's performance management, which is designed to motivate employees to continuously improve and improve work efficiency.
