Name the Job Before You Trust It: Understanding AI Layers and Its Applications in HR

You can download the document here

AI is already shaping how organizations recruit, analyze workforce trends and support employee development. But do we always understand what these tools are actually doing?

Our L3A AI in HR Working Group explores a simple, practical framework to help HR professionals distinguish between three AI capabilities:

Diagnostic AI — Why did this happen?

Predictive AI — What might happen next?

Generative AI — Can you produce this for me?

Why does this distinction matter?

Because the role of an AI tool determines the value it can deliver, the risks it may introduce and the level of human oversight it requires.

The key question is not simply whether we use AI, but whether we understand it well enough to use it responsibly.
