AI agent or automation?
How to tell which one you need.
Work with clear rules goes to automation. Work that needs judgment goes to an agent. Cost, build time and approvals differ.

Automation runs a task with clear rules through the same steps every time. An AI agent reads work that needs judgment and prepares a draft or a recommendation.
Before you hand a task to AI, the first question is whether it is done by rule or by judgment. The answer sets the build time, the price and where a person needs to approve.
Two definitions.
Automation
It runs the same steps in the same order every time. The logic is simple: if this happens, do that. The result does not change unless the rule does.
Typical work: writing a tracking number to an order, sending orders to accounting, adding a form entry to the CRM. More on process automation.
AI agent
It reads the incoming work, interprets it and prepares a draft or a recommendation. The same task arrives with different wording each time.
Typical work: drafting a reply to a customer message, reviewing a return request, interpreting the weekly ad report. More on AI agents.

Three questions to decide.
Break the work into steps and ask these in order for each step.
Is the work done with the same steps every time?
If yes, automation is enough.
Does someone have to read and interpret text?
If yes, you need an agent.
Does the result touch customers, money or campaigns?
If yes, add a human approval step.
Two example workflows.
The first workflow needs no judgment; a rule is enough. In the second, one step needs interpretation and one step brings in a person.

The two together.
Most agents are built together with an automation that runs underneath. The automation collects and moves the data, the agent interprets it, and you make the final call. So the question is rarely which one. It is which one at which step. In the systems we build, the agent does not decide on its own: it prepares, you approve.
If you are unsure, break the work into steps and ask the three questions for each step. Steps with clear rules go to automation, steps that need judgment go to an agent, and the final say stays with you.
