Amazon CEO Andy Jassy is doubling down on the company’s famous (and sometimes infamous) Leadership Principles by making them a formal part of employee performance reviews. Managers will now explicitly assess whether workers embody traits like "Customer Obsession" or "Invent and Simplify"—something that was previously more of an unspoken expectation. It’s a clear signal that Amazon wants to keep its hard-charging cultural identity intact, even as the company evolves post-Bezos.

Editor’s Note: Amazon’s leadership principles aren’t just motivational posters—they’re the backbone of how the company operates. By baking them into reviews, Jassy is making sure employees don’t just nod along but actually walk the talk. For workers, it could mean more pressure to align with Amazon’s famously intense ethos. For the company, it’s a way to maintain its DNA while scaling up. Love it or hate it, this is Amazon staying very Amazon.
