Hi! I have difficulty in understading "hold people accountable for them"

Thanks for your assistance.

I pasted the context below. Hope it might give you a hint.

Myth 6: It's important to lock in goals at the beginning of the year and hold people accountable for them.

The business environment has evolved. Markets can shift, new competitors can emerge, and priorities can change during the course of a year. Adaptability is a part of the performance management process. It's likely goals will change throughout the year. Adaptability is important in today’s business environment.
