Core Competency

In The Everything Store, core competency names the build-vs-outsource decision Amazon faced over distribution. Bezos and Jeff Wilke asked “a fundamental question that seems surprising today: Should Amazon even be in the business of storing and distributing its products?” — framed explicitly as “Was distribution a commodity or was it a core competency? If it’s a commodity, why invest in it?” Their answer ran counter to the asset-light instinct: third-party equipment and software “simply wasn’t designed for the task at hand,” so rather than exit distribution, Amazon rewrote all the software code and reinvested in it, turning fulfillment into a built, owned capability rather than an outsourced commodity.

The concept also marks the limit of competency-based reasoning. When Bezos decreed Amazon would build its own e-reader, the move was “well outside of Amazon’s core competency—its litany of obvious skills,” drawing “a chorus of vehement objections” — the Kindle bet deliberately pushed past the boundary. Kyle’s notes pin the idea to Jim Collins’s Good to Great counsel, delivered at an Amazon board offsite: “You’ve got to decide what you’re great at.”

Context: “Core competency” is a strategy term popularized by C.K. Prahalad and Gary Hamel (HBR, 1990) for the distinctive capabilities a firm should build around rather than outsource — exactly the build-vs-buy frame Bezos applied to Amazon’s logistics.
