La Minute Builder #8 — How do you know if your AI agent is truly successful?

In this edition of La Minute Builder, here are the 8 indicators I would track to measure the success of an AI agent.

Time saved

How many hours are actually saved?

Adoption rate

Are teams actually using it?

Usage frequency

Is it used every day, or only in demos?

Output quality

Are the responses reliable enough?

User satisfaction

Do users want to keep using it?

Productivity

Can teams focus on higher-value tasks?

Business impact

Does the agent generate revenue or reduce costs?

ROI

Does the value created exceed its cost?

IKEA & Billie (2021)

In 2021, when IKEA's AI agent Billie handled 47% of customer requests (transactional customer support), the company did not reduce headcount.

It retrained 8,500 advisors for remote interior design consulting — a channel that now generates €1.3 billion.

The trap? Measuring only what AI automates.

The most important KPI is the new value it unlocks.
