The marketing department at a large financial services company chooses five high-performing staff members every year to receive a performance award, which includes a monetary reward and recognition at an end-of-year meeting. Employees are chosen by managers in the marketing department. Each manager nominates two direct reports, and then all managers meet as a group to discuss nominees until a consensus is reached. The names of the winners are given to HR for final approval. The marketing department is preparing to begin this year's nomination process. There have been repeat winners in each of the last three years. A marketing employee files a complaint with the HR director about favoritism in the award process. Additionally, the employee points out that newer employees rarely win the award, which lowers their morale. New employees tend not to win because they spend a couple of years training and shadowing experienced employees before receiving tasks to perform independently.

How should the HR director minimize the perception of favoritism in the selection process?
