Reed Hastings argues board members lack daily context to add value with advice. Their true function is to be an "insurance layer," with their most crucial responsibility being the decision to replace the CEO if needed. They must learn the business not to advise, but to be prepared for that moment.

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.

A board member's role is to provide outside perspective to help a CEO think through a problem, not to make the decision. CEOs who ask 'what should we do?' risk abdicating responsibility to someone who lacks the deep operational context to make the right call. This can be destructive to a CEO's development.

Executives often interview by recounting past achievements, a "rear-view mirror" approach. To win a board seat, candidates must adopt a forward-looking governance mindset. This involves asking thought-provoking strategic questions about the future, demonstrating they can operate as a peer from day one.

If an interview feels easy because you are exclusively discussing your deep functional expertise, you are likely failing. Boards hire "T-shaped" directors who can connect specialized knowledge to broad strategic issues. You must resist going too deep and instead demonstrate wide-ranging strategic thinking.

At the VP or C-level, a leader's primary role shifts from managing their function to driving overall business success. Their focus becomes more external—customers, market, revenue—and their success is measured by their end-to-end impact on the company, not just their team's performance.

A common mistake for new leaders is prioritizing and defending their functional team. The correct approach is to view the executive leadership team as their "first team." This requires prioritizing the overall business, understanding cross-functional needs, and acting as a business leader first.

Harvey's COO doesn't own a single function like GTM. Instead, she tackles complex, cross-functional initiatives that the CEO would otherwise have to lead. She manages stakeholders and synthesizes options, effectively acting as a clone of the CEO for driving company-wide strategic projects and increasing his leverage.

The transition from manager to director requires a shift from managing tactical details to 'directing.' A director's value comes from high-level strategy, cross-departmental resource connection, and solving organizational problems, not from knowing more than their direct reports.
