How does RAG work?
One idea. Two skills.AI-generated illustration

You’ve saved the link. Now what?

Too much to follow.

The concepts don’t connect yet.

It makes sense—until it’s your turn to explain.

Three parts. One learning journey.

We curate original sources, build the foundations, and give you a place to practise.

All connected to the same idea.

Here’s what learning actually looks like.

Try a small part of lesson one: does faster drafting mean a faster job?

WHY THE ORIGINAL

The same person. A more useful answer.

Meet Mina, a product manager planning a support assistant.

BEFORE · the first planning meeting
“We’ll train it on our docs so it knows the latest policy.”

The goal is clear. The mechanism and the check are missing.

AFTER PRACTICE · a new design review
“I’d lean toward retrieval: our docs change weekly. The trade-off is a slower reply. I’d want to rule out outdated sources.”

I’d lean toward …

02
Make the trade-off explicit

BEYOND THE LESSON

Leave with something you can use.

Three situations. Three complete examples of what to practise.

01 / A NOTE TO YOUR TEAM

Explain what matters.

A teammate shares an impressive AI demo. You add the question the team needs to ask.

EXAMPLE OUTPUT
The demo looks promising. Before we adopt it, I’d test it on our own tickets.
Practise evidence and evaluation
02 / A PILOT PROPOSAL

Turn an idea into a next step.

Your team wants a support agent. You define the first boundary.

EXAMPLE OUTPUT
Let’s start with drafting. A person approves each reply before it reaches the customer.
Practise agents and boundaries
03 / A DESIGN REVIEW

Make a recommendation you can defend.

A stakeholder asks why you chose RAG. You explain the trade-off and the test.

EXAMPLE OUTPUT
Our policy changes weekly. I’d use retrieval—and check for missing or outdated sources.
Practise retrieval and trade-offs

Would the choice change with a different source label?

When an AI assistant shortlists options for work, check whether its choice follows your requirements or a familiar name.
