Accenture CEO Julie Sweet advised new Salesforce CFO Amy Weaver to identify and master the single most important source of credibility for her new role—in this case, Wall Street. Instead of trying to learn everything at once, she focused on excelling in investor relations to quickly establish her authority.

Qualified's CMO, Mara Rivera, argues that a leader's success isn't about being an expert in everything. The key is to conquer imposter syndrome and build a team of A-players in domains like demand gen or ops, who can then teach and guide you.

A mentor at Celgene advised that the best path to becoming its CFO was to leave and first become a public company CFO elsewhere. Large companies often prefer external candidates with proven executive track records for top roles, a credential that is difficult to gain by climbing the internal ladder.

When leading a function outside your expertise (e.g., a comms leader managing BDRs), success depends on hiring a great functional leader. Your role becomes asking them to explain concepts simply until you understand, trusting their expertise, and advocating for their needs, rather than trying to become the expert yourself.

While preparing for her CFO role, Amy Weaver was told by her Investor Relations lead that while her technical answer was correct, she didn't "sound like a CFO." This highlights the crucial, often overlooked, need to adopt the communication style and vocabulary expected of a role to gain full credibility.

The leap from a hands-on marketing leader to a C-level executive is less about tactical skills and more about personal growth. It demands a shift from execution ('doing the work') to leadership ('inspiring people'), which requires self-awareness, authenticity, and dropping 'professional walls' to build genuine connections.

Transitioning from a top-performing rep requires a mindset shift from doing to enabling. A new leader's role is not to teach their specific 'Michael Jordan' method, but to align company and personal goals, then focus on removing obstacles for each team member's unique path to success.

Unlike a functional manager who can develop junior talent, a CEO lacks the domain expertise to coach their entire executive team (e.g., CFO, VP of HR). A CEO's time is better spent hiring world-class leaders who provide 'managerial leverage' by bringing new ideas and driving their function forward, rather than trying to fix people in roles they've never done.

Unlike a line manager who can train direct reports in a specific function, a CEO hires experts for roles they themselves cannot perform (e.g., CFO). A CEO's time spent trying to 'develop' an underperforming executive is a misallocation of their unique responsibilities, which are setting direction and making top-level decisions.
