Bryar and Carr, both former Amazon executives, take a detailed informative firsthand look at the company's "unique principles and processes." The authors reveal founder the four core pillars established by founder Jeff Bezos to make up Amazon's culture: customer obsession, long-term thinking, eagerness to invent, and operational excellence. The authors then outline the 14 "Leadership Principles" crafted to achieve those four goals; these include frugality ("constraints breed resourcefulness"), earning trust (by "being vocally self-critical"), and focusing more on customers than competitors. This last point leads the authors to discuss Bezos's approach for programs such as the Kindle e-reader and e-book store and Prime Video: the company used a "Working Backwards" process that began with the desired customer experience and then designed products to achieve it. While the writing can be entertaining, the authors' personal anecdotes of working at the company get to be repetitive and--combined with their habit of referring to Bezos by his first name--often feel like they are used to highlight their access. Still, they deliver an information-packed guide to Amazon's success. Readers are sure to extract lessons applicable to organizations large and small. (Feb.)
