Question 1

What is the Build-Measure-Learn loop?

Accepted Answer

A continuous feedback cycle from Lean Startup where a team builds a minimal version of an idea, measures how customers respond, and learns whether to persevere or pivot.

Question 2

Who created the Build-Measure-Learn loop?

Accepted Answer

Eric Ries introduced it in his 2011 book "The Lean Startup," drawing on lean manufacturing and Steve Blank's Customer Development framework.

Question 3

What are the three stages of the loop?

Accepted Answer

Build (create a minimal experiment), Measure (collect real customer data), and Learn (decide whether to persevere with or pivot from the idea).

Question 4

Why do you plan the loop backwards?

Accepted Answer

Because you should start from what you need to learn, then decide what to measure, then figure out what to build, which keeps the experiment focused and honest.

Question 5

What is "validated learning"?

Accepted Answer

Ries's term for knowledge about customers backed by real evidence. It's the true output of the loop, more important than the feature itself.

Question 6

How does the loop relate to an MVP?

Accepted Answer

The Build stage often produces a Minimum Viable Product, the smallest thing capable of testing a specific hypothesis with real customers.

Question 7

What does it mean to "pivot"?

Accepted Answer

To change direction based on what a loop revealed, rather than persevering with an assumption the evidence didn't support.

Question 8

How is the loop different from just shipping features?

Accepted Answer

Shipping features focuses on output; the loop focuses on learning. A loop that ships something but teaches nothing has failed, even if the feature works.

Question 9

What's the most common mistake with the loop?

Accepted Answer

Building too much before measuring, or planning the loop forwards and only afterward looking for a metric to justify what was built.

Question 10

Can Agile teams use the Build-Measure-Learn loop?

Accepted Answer

Yes. Agile sprints can house one or more trips through the loop, using each sprint to complete an experiment rather than just deliver features.
