Someone must hold final operational responsibility for the entire organization. The chief executive officer, or CEO, is that person. The CEO reports to the board of directors, sets overall strategy, leads the senior management team, and represents the company to external stakeholders. In smaller firms the CEO may also handle day-to-day decisions; in larger ones the role is more focused on direction and culture.

Selection of a CEO is one of the board’s most consequential decisions. The right leader can align the organization and drive performance; the wrong one can destroy value quickly. Compensation, succession planning, and evaluation of the CEO are ongoing board responsibilities. Public-company CEOs face additional scrutiny from investors, analysts, and the media.

The title carries both authority and accountability. Successes are often attributed to the CEO; failures likewise. Effective CEOs balance confidence with openness to challenge, long-term vision with short-term results, and internal leadership with external representation. The role remains one of the most visible and demanding in organizational life.
