A closer look

General Magic taught Fadell that great tech fails without a clear customer. The team built a device too early, before the market or networks were ready.

At Apple, the iPod came together fast. Fadell explains how they used existing parts, worked with partners and focused on a simple experience.

Nest started when he couldn't find a good thermostat for his house. He built a team that cared about design and energy savings, and the product changed a dull category.

He also writes about being a manager for the first time. He admits mistakes and shares advice on giving feedback and running meetings.

Business lessons from the book

Storytelling: why it matters.
Prototyping: build to learn.
Customer journey: every touch point.
Hiring: build great teams.

Who should read it

Product founders, hardware builders and new managers.

Tips from readers, plus one of ours

Skip to the chapters you need. Readers say it works best as a handbook you dip into for careers, building products, or running a team.
Notice the line between data and opinion decisions. Kyle Evans's Product Thinking review highlights Fadell's point that some choices can't wait for data, like the iPhone dropping a physical keyboard.
Design the whole customer journey. The same review retells how Nest found half of install time went to finding tools, so they put a screwdriver in the box.
Product managers often single out the chapter on what a great PM does as one of the best on the subject.
Agree or disagree: some readers say his advice only works at Apple scale. We disagree. The Nest screwdriver and pre-charged iPod stories are small decisions any team can copy.
Our unusual tip: pick a product you use every day and write out every step from first seeing it to using it for a month. Mark the one step that annoyed you most, then look for the same step in your own work, which is the kind of whole-journey check Fadell describes in the Nest stories.
