Delivering Happiness: A Path to Profits, Passion, and Purpose
Source: https://www.hachettebookgroup.com/titles/tony-hsieh/delivering-happiness/9780446563048/ ↗
Hsieh's account of building Zappos and the culture that made it distinctive — specific hiring practices, obsessive customer service, the explicit investment in employee happiness as a business strategy.
The book is part memoir and part manifesto, and both registers show; it is honest about failures as well as successes.
For product direction the value is the operational material: Zappos's mechanisms for producing culture were deliberate and specific, not incidental.
Hsieh died in 2020 and the book reads differently now; the later chapters on Holacracy (which Zappos eventually abandoned) are a useful cautionary tale in themselves.
Read as a primary source rather than a playbook.
