Engineering leadership involves four distinct skills: Technical, Operations, Product, and Strategy. Since no single person excels at all four, organizations should build complementary leadership teams, pairing a visionary CTO with a process-driven VP of Engineering.

To become a more effective leader with a holistic business view, deliberately seek experience across various interconnected functions like operations, marketing, and sales. This strategy prevents the narrow perspective that often limits specialized leaders, even if it requires taking lateral or junior roles to learn.

The most effective operators, dubbed 'dolphins,' can fluidly move between altitudes: operating strategically at 10,000 feet with founders, managing at 5,000 feet, and executing tactically in the weeds at 1,000 feet. This ability to oscillate is a key trait to hire for, especially in advisory or early-stage leadership roles.

To be truly successful, a product leader cannot just focus on features and users. They must operate as the head of their product's business, with a deep understanding of P&Ls, revenue drivers, and capital allocation. Without this business acumen, they risk fundamentally undercutting their product's potential impact and success.

Effective long-term leadership isn't static; it's an 'accordion' that flexes between deep involvement and granting autonomy. This adaptive approach is key for different company seasons, knowing when to lean into details and when to empower the team to make 'foot fault' mistakes and learn.

The best leaders don't just stay high-level. They retain the ability to dive deep into technical details to solve critical problems. As shown by Apple's SVP of Software, this hands-on capability builds respect and leads to better outcomes, challenging the 'empower and get out of the way' mantra.

Effective leaders must also be effective managers. Management is the tactical subset of leadership. For example, a manager tracks KPIs like conversion rates, but a leader investigates the 'why' behind an individual's poor metrics, diagnosing and coaching on specific skill or knowledge gaps. You must fluidly do both.

The most valuable professionals are neither pure visionaries nor pure executioners; they are "step builders." This means they can understand a high-level strategic vision and then map out the granular, sequential steps required to achieve it. This skill is critical for turning ambitious goals into reality.

To truly understand a business, leaders should spend time in a non-scientific, operational role like IT. This 'back of house' experience provides an invaluable perspective on how an organization functions, what other teams value, and the real-world impact of change, creating a more empathetic and effective leader.
