Why we picked it
The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

- Talk about their life, not your idea.
- Ask about specifics in the past, not opinions about the future.
- 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

To say no to the right requests you need feedback you can trust, and this shows how to get it by watching customers rather than just taking their asks. It reinforces that observing the struggle tells you more than the feature name they hand you. Practical field technique for separating a stated want from a real need.

This is the practical how-to for actually running the weekly cadence, covering the part most founders get stuck on: recruiting people and making sense of what they said. Torres favors story based interviews where you ask about a specific recent instance rather than generalities. Use it as your operating manual for keeping a steady interview stream alive.

A transcript of a real switch interview so you can hear what a great customer conversation actually sounds like. Reading it shows how a skilled interviewer follows the timeline of a purchase and keeps digging without leading. Much more useful than abstract advice when you are learning to run these yourself.
From
Jobs to be Done Radio
- See a real interview unfold instead of reading rules about one
- Notice how the interviewer follows the timeline of the decision
- Small 'why did you do that' probes uncover the real motivation

Ash Maurya, author of Running Lean, argues you can always find how a customer solves a job today, and that existing workaround is your evidence. The piece gives you the switching forces (push, pull, inertia, friction) to read whether the pain is urgent enough that someone would actually change and pay. It is a concrete, interview ready way to separate a real painkiller from a vitamin.

- Every job already has an existing alternative (even a spreadsheet or a manual hack); if you cannot find one, the problem may not be real.
- How hard the current workaround is, and what would make someone abandon it, tells you the true urgency and willingness to pay.
- Pull the problem out of the customer's actual recent story rather than asking them to predict future behavior.

Hall's book gives you the research discipline behind good interviewing: how to avoid leading a witness, how to write a discussion guide, and how to separate what you observed from what you interpreted. It's aimed at product teams generally, so it's broader than customer development books, but the interviewing chapters translate directly to founder conversations. It's a fast read and cuts the fluff other research books carry.
From
A Book Apart / Erika Hall
by Erika Hall
~120 pages
- Write your questions down in advance, improvising under pressure tends to lead the witness.
- Separate your notes into said, did, and your interpretation, don't blend them.
- A clear purpose statement and informed consent make people more honest, not less.

The book that coined get out of the building and launched the customer development movement. Blank's core claim is that a startup searches for a business model rather than executes one, so your early job is to test hypotheses against real customers before you scale anything. It is heavier than The Mom Test, but it gives you the full framework for validating a market before you build for it.

- Startups search for a business model, they do not just execute a plan
- Test your riskiest assumptions with real customers before committing to build
- Customer discovery and validation come before you spend on customer creation
