While the process of acquiring businesses is exciting, managing a large portfolio of acquired companies shifts the CEO's job dramatically. The role becomes less about the 'chase' of deals and growth, and more about managing personnel issues, retaining key talent from acquired firms, and solving interpersonal conflicts—a draining reality of scale.

The era of stable, long-term planning is over. In a volatile environment, plans become obsolete quickly. The new leadership model is to ensure everyone deeply understands the company's direction and vision, empowering them to constantly adapt their tactics to reach the goal, rather than rigidly follow an outdated plan.

A CEO who stays too long creates an organization optimized to respond only to them, causing other skills and response mechanisms to weaken. Leadership changes are healthy because they force a company to develop a more balanced and resilient set of capabilities, breaking the imperial CEO model.

For startups experiencing hypergrowth, the ideal HR leader has experience not just in growth, but in chaotic, high-stress environments. These individuals, often veterans of companies like early Uber, have the resilience and scar tissue necessary to navigate the inevitable cultural and organizational challenges.

To avoid repeating its prior chaotic CEO succession, Disney orchestrated a highly public and well-managed 'bake-off' between internal candidates. This telegraphed process, overseen by an external chairman famed for succession planning, stabilized the company and provides a model for other large corporations.

To avoid repeating the Bob Chapek succession "fiasco," Disney's board deliberately structured the process to retain the runner-up. By creating a new President and Chief Creative Officer role, they ensured the finalist had a strong partner and prevented a disruptive executive exit.

Harvey CEO Winston Weinberg experiences a four-month cycle of accumulating pressure from unsolved problems. He argues the only release is a fundamental reinvention: making a new leadership hire, restructuring the company, or cutting a failing initiative. This cycle is necessary to unlock the next stage of scale.

With increasing uncertainty from geopolitics, inflation, and AI, a leader's past experience is less predictive of success. Hiring should prioritize mindset, attitude, and the ability to manage change over a specific experiential playbook, which may now be obsolete.

Companies typically promote CEOs from within. An external hire implies a crisis or a failure of succession planning. Therefore, an incoming external CEO has a mandate for significant change. Playing it safe with incremental adjustments squanders the opportunity and fails to address underlying issues.
