Write as the CEO/Leader of a company and use this question as a guide to your writing. "How can a leader use HRM as a function that will contribute to goals of the organization?"
When you are thinking of a leader of a company in achieving its goals, a good way to approach this (not the only way) is to think of some corporate objectives a company might have, then think about the relationship the CEO would have with the HR department and what kinds of things he or she might have HR do or help the CEO do.
