What is agentic AI?

Agentic AI describes systems that pursue a goal across multiple steps, choosing their own actions and using tools along the way, rather than answering a single prompt. The governance question changes with it: instead of reviewing one output, you are deciding in advance which actions an agent may take unsupervised and where a human must approve.

Why it matters for a UK business

It is the difference between a tool that answers when asked and one that acts on its own initiative. That is useful for work that varies each time, and risky for work where a wrong step is expensive and nobody was watching.

What it looks like in practice

An agent is given a goal and a set of tools, and works out the steps itself. It might read the inbox, draft replies, update the CRM and book the follow-up without being told each step. The value is in the autonomy. So is the risk.

What to do about it

Draw the boundary before building anything: what it may do unattended, what needs a person before it proceeds, what it must never touch. The boundary is the design decision. The rest is configuration.
