When new leadership arrives, a long-serving executive's value lies in their deep institutional knowledge and cross-functional relationships. They can act as a crucial bridge, helping synthesize diverse perspectives to guide the new team's vision and ensure a smoother transition.

In a turnaround, a leader's most critical first step is restructuring their direct reports. McLaren's CEO replaced every key leader—CFO, HR, commercial, etc.—to create a unified group that could then drive cultural change down through their own departments.

When an executive leaves, the CEO should step in to run their department directly. This provides invaluable operational context for hiring a replacement and empowers the CEO to make necessary but difficult changes (org structure, personnel) that a new hire would hesitate to implement.

Effective leadership transitions must be planned years in advance. The successor should gradually assume managerial duties, making the final handover a natural, expected event for employees and LPs. Rushed plans fail, especially if the departing leader isn't truly ready to retire.

Strategic decisions, especially painful ones like layoffs or shuttering a project, require removing personal emotion. A CEO's primary responsibility is to the company's strategic health and its investors, even when it conflicts with attachments.

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.

Instead of abrupt changes, Sequoia employs a gradual, multi-year transition process for its leadership stewards. Past leaders like Michael Moritz and Doug Leone remained involved for years after handing over the reins, ensuring stability and continuity for the firm and its LPs.

Successor CEOs cannot replicate the founder's all-encompassing "working memory" of the company and its products. Recognizing this is key. The role must shift from knowing everything to building a cohesive team and focusing on the few strategic decisions only the CEO can make.

After buying back Beautycounter's assets, Renfrew realized she couldn't continue operations with the existing overhead. The brutal but necessary first step was to let go of most employees without severance to conserve scarce capital, close the old chapter, and enable a genuine restart.
