Citing extensive research, McKinsey's leader asserts that organizational speed is a critical performance driver. Faster companies consistently outperform more cautious, slower-moving competitors, suggesting that a bias for action is more valuable than avoiding all errors, despite corporate risk aversion.

Challenge the 'hire slow' mantra. Hiring is an intuitive guess, so act quickly. Once a person is in the organization, their performance is a known fact, not a guess. This clarity allows for faster decisions—both in removing underperformers and, crucially, in accelerating the promotion of superstars ahead of standard review cycles.

The founders resolve the tension between speed and quality by being "obsessive." They move fast by iterating constantly, but also relentlessly go back and refine existing work. Speed is about the pace of iteration and a commitment to delight, not about shipping once and moving on.

The greatest performers, from athletes to companies, are not just the most talented; they are the best at getting better faster. An obsession with root-cause analysis and a non-defensive commitment to improvement is the key to reaching otherwise unachievable levels of success.

The conventional wisdom that you must sacrifice one of quality, price, or speed is flawed. High-performance teams reject this trade-off, understanding that improving quality is the primary lever. Higher quality reduces rework and defects, which naturally leads to lower long-term costs and faster delivery, creating a virtuous cycle.

In a competitive market, prioritizing speed forces a team to be resourceful and figure out how to maintain quality under pressure. This mindset prevents the design team from becoming a bottleneck and keeps the company's momentum high.

Effective engineering leadership is like farming: growth isn't achieved by demanding it from the plants. Leaders should obsess over inputs—clear goals, sound strategy, team structure, and operational rigor—to create the conditions for great engineering to happen naturally.

Mid-level performers often say yes to urgent, low-value client requests (like personally delivering a part) to show good service. Top performers delegate or decline, understanding that a two-hour task costs thousands in opportunity cost, far outweighing a hundred-dollar courier fee. This requires valuing your time at a high hourly rate.

To prevent engineers from focusing internally on technical purity (e.g., unnecessary refactoring), leaders must consistently frame all work in terms of its value to the customer. Even tech debt should be justified by its external impact, such as improving security or enabling future features.
