The definition of a HR business partner is an experienced human resource professional who works directly with an organization's senior leadership to develop and direct an HR agenda that closely supports organizational goals. Rather than working primarily as part of the internal human resources department, the HR business partner works closely with senior leadership, perhaps sitting on the board of directors or collaborating regularly with the C-suite. Placing a human resources professional in close contact with executive leadership makes HR a part of the organizational strategy. The business partner model for human resources is becoming more and more popular among business organizations.
