Inspired: How to Create Tech Products Customers Love

by Marty Cagan

Key Ideas

  1. What a customer asks for is a symptom, not a prescription: a team that fills orders on time can spend an entire year treating the wrong illness.
  2. Everyone tests whether the screen is understandable; almost nobody tests whether anyone cares — and that's the question that cancels quarters.
  3. Being wrong isn't the problem. Finding out after you've paid for the finished software is.
  4. A useful prototype is the cheapest artifact capable of producing a real decision; if you can't throw it away, it stopped being a prototype.
  5. The org chart decides which product is possible: a team that can't cancel anything isn't empowered, it just has a nicer name.

The promise

There's a very modern way to fail: on schedule. The team closes every sprint, the charts stay green, the quarterly plan lands almost intact — and at the end of the year the business is sitting where it started. Nobody was lazy. The factory ran beautifully; what was wrong was what we fed into it.

That's the gap Marty Cagan's ideas attack, and the claim is uncomfortable precisely because it sounds so cheap. Two companies with equally capable people and comparable budgets end up in very different places because of one variable almost nobody audits: the mechanism by which they decide what to build. That's not an effort problem, it's an organizational design problem — good news, since you're already giving the effort. Here we explain the ideas we find most useful, test them against outside evidence, show where they break, and give you a way to try them this week.

The idea in one image

In much of the world you can walk into a pharmacy, say "give me the antibiotic that worked for my cousin," and walk out with it. Nobody asks what hurts or how long it's been hurting. The counter is beautifully efficient: fast, cheap, and you leave satisfied. Which is exactly what makes it dangerous — it treats your self-diagnosis as a diagnosis.
