Amazon vs. Netflix: A Leader's Take on Culture
In a recent interview, leader Cristina Sancho, who moved from Amazon to Netflix, discussed the critical cultural differences between the two tech giants. She highlights that at Netflix, candor is expected but must be paired with empathy, and emphasizes the importance of knowing when to move on from a project or role that is no longer high-leverage.
At Netflix, the principle of "context, not control" governs engineering leadership. Managers are expected to provide their teams with the necessary strategic context—goals, constraints, and alignment with company objectives—and then trust their highly-skilled engineers to execute without micromanagement. This approach fosters a culture of autonomy and ownership, where individual contributors are empowered to make significant decisions. In contrast, Amazon's engineering culture is built on a foundation of data-driven rigor and specific leadership principles. Concepts like "two-pizza teams" ensure small, agile groups with single-threaded ownership over their services, from ideation to operation. This structure is designed to minimize communication overhead and maximize focus and speed. A key differentiator is the approach to disagreement. At Amazon, the "Have Backbone; Disagree and Commit" principle is a core tenet. This means leaders are expected to challenge decisions they disagree with, using data to support their arguments, but once a decision is made, they must commit fully to its execution. Misapplication of this can lead to a culture where it's perceived as "my way or the highway," as noted by Cristina Sancho. Netflix's performance management is known for its "Keeper Test," where managers regularly assess if they would fight to keep an employee. This fosters a high-talent-density environment, viewing the company as a professional sports team rather than a family, where tough personnel decisions are made to ensure the best player is in every position. Formal performance reviews are eschewed in favor of continuous, candid 360-degree feedback. Decision-making at Netflix is decentralized, with an emphasis on each employee acting as an "informed captain." Individuals are responsible for gathering the necessary context to make the best decision for the company, and are then held accountable for the outcomes. This contrasts with a more hierarchical, approval-based system, empowering employees to take calculated risks. At Amazon, engineering managers are evaluated on their ability to "Hire and Develop the Best" and "Deliver Results," with a strong emphasis on operational metrics. The culture is one where what can't be measured often doesn't exist, and a significant part of a manager's role involves deep-diving into data to find the root cause of issues. Ultimately, Netflix's model is designed for innovation and flexibility, attracting senior engineers who thrive on autonomy and responsibility. Amazon's structure is geared for scalable, efficient execution, with clear mechanisms for problem-solving and a culture that values deep technical expertise and operational excellence.
